Help, My Student has a Huge Score Discrepancy Between Tests and I Don’t Know Why?

Here’s a  familiar scenario to many SLPs. You’ve administered several standardized language tests to your student (e.g., CELF-5 & TILLS). You expected to see roughly similar scores across tests. Much to your surprise, you find that while your student attained somewhat average scores on one assessment, s/he had completely bombed the second assessment, and you have no idea why that happened.

So you go on social media and start crowdsourcing for information from a variety of SLPs located in a variety of states and countries in order to figure out what has happened and what you should do about this. Of course, the problem in such situations is that while some responses will be spot on, many will be utterly inappropriate. Luckily, the answer lies much closer than you think, in the actual technical manual of the administered tests.

So what is responsible for such as drastic discrepancy?  A few things actually. For starters, unless both tests were co-normed (used the same sample of test takers) be prepared to see disparate scores due to the ability levels of children in the normative groups of each test.  Another important factor involved in the score discrepancy is how accurately does the test differentiate disordered children from typical functioning ones.

Let’s compare two actual language tests to learn more. For the purpose of this exercise let us select The Clinical Evaluation of Language Fundamentals-5 (CELF-5) and the Test of Integrated Language and Literacy (TILLS).   The former is a very familiar entity to numerous SLPs, while the latter is just coming into its own, having been released in the market only several years ago.

Both tests share a number of similarities. Both were created to assess the language abilities of children and adolescents with suspected language disorders. Both assess aspects of language and literacy (albeit not to the same degree nor with the same level of thoroughness).  Both can be used for language disorder classification purposes, or can they?

Actually, my last statement is rather debatable.  A careful perusal of the CELF – 5 reveals that its normative sample of 3000 children included a whopping 23% of children with language-related disabilities. In fact, the folks from the Leaders Project did such an excellent and thorough job reviewing its psychometric properties rather than repeating that information, the readers can simply click here to review the limitations of the CELF – 5 straight on the Leaders Project website.  Furthermore, even the CELF – 5 developers themselves have stated that: “Based on CELF-5 sensitivity and specificity values, the optimal cut score to achieve the best balance is -1.33 (standard score of 80). Using a standard score of 80 as a cut score yields sensitivity and specificity values of .97.

In other words, obtaining a standard score of 80 on the CELF – 5 indicates that a child presents with a language disorder. Of course, as many SLPs already know, the eligibility criteria in the schools requires language scores far below that in order for the student to qualify to receive language therapy services.

In fact, the test’s authors are fully aware of that and acknowledge that in the same document. “Keep in mind that students who have language deficits may not obtain scores that qualify him or her for placement based on the program’s criteria for eligibility. You’ll need to plan how to address the student’s needs within the framework established by your program.”

But here is another issue – the CELF-5 sensitivity group included only a very small number of: “67 children ranging from 5;0 to 15;11”, whose only requirement was to score 1.5SDs < mean “on any standardized language test”.  As the Leaders Project reviewers point out: “This means that the 67 children in the sensitivity group could all have had severe disabilities. They might have multiple disabilities in addition to severe language disorders including severe intellectual disabilities or Autism Spectrum Disorder making it easy for a language disorder test to identify this group as having language disorders with extremely high accuracy. ” (pgs. 7-8)

Of course, this begs the question,  why would anyone continue to administer any test to students, if its administration A. Does not guarantee disorder identification B. Will not make the student eligible for language therapy despite demonstrated need?

The problem is that even though SLPs are mandated to use a variety of quantitative clinical observations and procedures in order to reliably qualify students for services, standardized tests still carry more value then they should.  Consequently,  it is important for SLPs to select the right test to make their job easier.

The TILLS is a far less known assessment than the CELF-5 yet in the few years it has been out on the market it really made its presence felt by being a solid assessment tool due to its valid and reliable psychometric properties. Again, the venerable Dr. Carol Westby had already done such an excellent job reviewing its psychometric properties that I will refer the readers to her review here, rather than repeating this information as it will not add anything new on this topic. The upshot of her review as follows: “The TILLS does not include children and adolescents with language/literacy impairments (LLIs) in the norming sample. Since the 1990s, nearly all language assessments have included children with LLIs in the norming sample. Doing so lowers overall scores, making it more difficult to use the assessment to identify students with LLIs. (pg. 11)”

Now, here many proponents of inclusion of children with language disorders in the normative sample will make a variation of the following claim: “You CANNOT diagnose a language impairment if children with language impairment were not included in the normative sample of that assessment!Here’s a major problem with such assertion. When a child is referred for a language assessment, we really have no way of knowing if this child has a language impairment until we actually finish testing them. We are in fact attempting to confirm or refute this fact, hopefully via the use of reliable and valid testing. However, if the normative sample includes many children with language and learning difficulties, this significantly affects the accuracy of our identification, since we are interested in comparing this child’s results to typically developing children and not the disordered ones, in order to learn if the child has a disorder in the first place.  As per Peña, Spaulding and Plante (2006), “the inclusion of children with disabilities may be at odds with the goal of classification, typically the primary function of the speech pathologist’s assessment. In fact, by including such children in the normative sample, we may be “shooting ourselves in the foot” in terms of testing for the purpose of identifying disorders.”(p. 248)

Then there’s a variation of this assertion, which I have seen in several Facebook groups: “Children with language disorders score at the low end of normal distribution“.  Once again such assertion is incorrect since Spaulding, Plante & Farinella (2006) have actually shown that on average, these kids will score at least 1.28 SDs below the mean, which is not the low average range of normal distribution by any means.  As per authors: “Specific data supporting the application of “low score” criteria for the identification of language impairment is not supported by the majority of current commercially available tests. However, alternate sources of data (sensitivity and specificity rates) that support accurate identification are available for a subset of the available tests.” (p. 61)

Now, let us get back to your child in question, who performed so differently on both of the administered tests. Given his clinically observed difficulties, you fully expected your testing to confirm it. But you are now more confused than before. Don’t be! Search the technical manual for information on the particular test’s sensitivity and specificity to look up the numbers.   Vance and Plante (1994) put forth the following criteria for accurate identification of a disorder (discriminant accuracy): “90% should be considered good discriminant accuracy; 80% to 89% should be considered fair. Below 80%, misidentifications occur at unacceptably high rates” and leading to “serious social consequences” of misidentified children. (p. 21)

Review the sensitivity and specificity of your test/s, take a look at the normative samples, see if anything unusual jumps out at you, which leads you to believe that the administered test may have some issues with assessing what it purports to assess. Then, after supplementing your standardized testing results with good quality clinical data (e.g., narrative samples, dynamic assessment tasks, etc.), consider creating a solidly referenced purchasing pitch to your administration to invest in more valid and reliable standardized tests.

Hope you find this information helpful in your quest to better serve the clients on your caseload.

Components of Qualitative Writing Assessments: What Exactly are We Trying to Measure?

Writing! The one assessment area that challenges many SLPs on daily basis! If one polls 10 SLPs on the topic of writing, one will get 10 completely different responses ranging from agreement and rejection to the diverse opinions regarding what should actually be assessed and how exactly it should be accomplished.

Consequently, today I wanted to focus on the basics involved in the assessment of adolescent writing. Why adolescents you may ask? Well, frankly because many SLPs (myself included) are far more likely to assess the writing abilities of adolescents rather than elementary-aged children.

Often, when the students are younger and their literacy abilities are weaker, the SLPs may not get to the assessment of writing abilities due to the students presenting with so many other deficits which require precedence intervention-wise. However, as the students get older and the academic requirements increase exponentially, SLPs may be more frequently asked to assess the students’ writing abilities because difficulties in this area significantly affect them in a variety of classes on a variety of subjects.

So what can we assess when it comes to writing? In the words of Helen Lester’s character ‘Pookins’: “Lots!”  There are various types of writing that can be assessed, the most common of which include: expository, persuasive, and fictional. Each of these can be used for assessment purposes in a variety of ways.

To illustrate, if we chose to analyze the student’s written production of fictional narratives then we may broadly choose to analyze the following aspects of the student’s writing: contextual conventions and writing composition.

The former looks at such writing aspects as the use of correct spelling, punctuation, and capitalization, paragraph formation, etc.

The latter looks at the nitty-gritty elements involved in plot development. These include effective use of literate vocabulary, plotline twists, character development,  use of dialogue, etc.

Perhaps we want to analyze the student’s persuasive writing abilities. After all, high school students are expected to utilize this type of writing frequently for essay writing purposes.  Actually, persuasive writing is a complex genre which is particularly difficult for students with language-learning difficulties who struggle to produce essays that are clear, logical, convincing, appropriately sequenced, and take into consideration opposing points of view. It is exactly for that reason that persuasive writing tasks are perfect for assessment purposes.

But what exactly are we looking for analysis wise? What should a typical 15 year old’s persuasive essays contain?

With respect to syntax, a typical student that age is expected to write complex sentences possessing nominal, adverbial, as well as relative clauses.

With the respect to semantics, effective persuasive essays require the use of literate vocabulary words of low frequency such as later developing connectors (e.g., first of all, next, for this reason, on the other hand, consequently, finally, in conclusion) as well as metalinguistic and metacognitive verbs (“metaverbs”) that refer to acts of speaking (e.g., assert, concede, predict, argue, imply) and thinking (e.g., hypothesize, remember, doubt, assume, infer).

With respect to pragmatics, as students  mature, their sensitivity to the perspectives of others improves, as a result, their persuasive essays increase in length (i.e., total number of words produced) and they are able to offer a greater number of different reasons to support their own opinions (Nippold, Ward-Lonergan, & Fanning, 2005).

Now let’s apply our knowledge by analyzing a writing sample of a 15-year-old with suspected literacy deficits. Below 10th-grade student was provided with a written prompt first described in the Nippold, et al, 2005 study, entitled: “The Circus Controversy”.   “People have different views on animals performing in circuses. For example, some people think it is a great idea because it provides lots of entertainment for the public. Also, it gives parents and children something to do together, and the people who train the animals can make some money. However, other people think having animals in circuses is a bad idea because the animals are often locked in small cages and are not fed well. They also believe it is cruel to force a dog, tiger, or elephant to perform certain tricks that might be dangerous. I am interested in learning what you think about this controversy, and whether or not you think circuses with trained animals should be allowed to perform for the public. I would like you to spend the next 20 minutes writing an essay. Tell me exactly what you think about the controversy. Give me lots of good reasons for your opinion. Please use your best writing style, with correct grammar and spelling. If you aren’t sure how to spell a word, just take a guess.”(Nippold, Ward-Lonergan, & Fanning, 2005)

He produced the following written sample during the allotted 20 minutes.

Analysis: This student was able to generate a short, 3-paragraph, composition containing an introduction and a body without a definitive conclusion. His persuasive essay was judged to be very immature for his grade level due to significant disorganization, limited ability to support his point of view as well as the presence of tangential information in the introduction of his composition, which was significantly compromised by many writing mechanics errors (punctuation, capitalization, as well as spelling) that further impacted the coherence and cohesiveness of his written output.

The student’s introduction began with an inventive dialogue, which was irrelevant to the body of his persuasive essay. He did have three important points relevant to the body of the essay: animal cruelty, danger to the animals, and potential for the animals to harm humans. However, he was unable to adequately develop those points into full paragraphs. The notable absence of proofreading and editing of the composition further contributed to its lack of clarity. The above coupled with a lack of a conclusion was not commensurate grade-level expectations.

Based on the above-written sample, the student’s persuasive composition content (thought formulation and elaboration) was judged to be significantly immature for his grade level and is commensurate with the abilities of a much younger student.  The student’s composition contained several emerging claims that suggested a vague position. However, though the student attempted to back up his opinion and support his position (animals should not be performing in circuses), ultimately he was unable to do so in a coherent and cohesive manner.

Now that we know what the student’s written difficulties look like, the following goals will be applicable with respect to his writing remediation:

Long-Term Goals:  Student will improve his written abilities for academic purposes.

  • Short-Term Goals
  1. Student will appropriately utilize parts of speech (e.g., adjectives, adverbs, prepositions, etc.)  in compound and complex sentences.
  2. Student will use a variety of sentence types for story composition purposes (e.g., declarative, interrogative, imperative, and exclamatory sentences).
  3. Student will correctly use past, present, and future verb tenses during writing tasks.
  4. Student will utilize appropriate punctuation at the sentence level (e.g., apostrophes, periods, commas, colons, quotation marks in dialogue, and apostrophes in singular possessives, etc.).
  5. Student will utilize appropriate capitalization at the sentence level (e.g., capitalize proper nouns, holidays, product names, titles with names, initials, geographic locations, historical periods, special events, etc.).
  6. Student will use prewriting techniques to generate writing ideas (e.g., list keywords, state key ideas, etc.).
  7. Student will determine the purpose of his writing and his intended audience in order to establish the tone of his writing as well as outline the main idea of his writing.
  8. Student will generate a draft in which information is organized in chronological order via use of temporal markers (e.g., “meanwhile,” “immediately”) as well as cohesive ties (e.g., ‘but’, ‘yet’, ‘so’, ‘nor’) and cause/effect transitions (e.g., “therefore,” “as a result”).
  9. Student will improve coherence and logical organization of his written output via the use of revision strategies (e.g., modify supporting details, use sentence variety, employ literary devices).
  10. Student will edit his draft for appropriate grammar, spelling, punctuation, and capitalization.

There you have it. A quick and easy qualitative writing assessment which can assist SLPs to determine the extent of the student’s writing difficulties as well as establish writing remediation targets for intervention purposes.

Using a different type of writing assessment with your students? Please share the details below so we can all benefit from each others knowledge of assessment strategies.

FREE Resources for Working with Russian Speaking Clients: Part III Introduction to “Dyslexia”

Image result for дислексияGiven the rising interest in recent years in the role of SLPs in the treatment of reading disorders, today I wanted to share with parents and professionals several reputable  FREE resources on the subject of “dyslexia” in Russian-speaking children.

Now if you already knew that there was a dearth of resources on the topic of treating Russian speaking children with language disorders then it will not come as a complete shock to you that very few legitimate sources exist on this subject.

Related imageFirst up is the Report on the Russian Language for the World Dyslexia Forum 2010 by Dr. Grigorenko, the coauthor of the Dyslexia Debate. This 25-page report contains important information including Reading/Writing Acquisition of Russian in the Context of Typical and Atypical Development as well as on the state of Individuals with Dyslexia in Russia.

Related imageNext up is this delightful presentation entitled: “If John were Ivan: Would he fail in reading? Dyslexia & dysgraphia in Russian“. It is a veritable treasure trove of useful information on the topics of:

  • The Russian language
  • Literacy in Russia (Russian Federation)
  • Dyslexia in Russia
    • Definition
    • Identification
    • Policy
  • Examples of good practice
    • Teaching reading/language arts
      • In regular schools
      • In specialized settings
    • Encouraging children to learn

Image result for orthographyNow let us move on to the “The Role of Phonology, Morphology, and Orthography in English and Russian Spelling” which discusses that “phonology and morphology contribute more for spelling of English words while orthography and morphology contribute more to the spelling of Russian words“. It also provides clinicians with access to the stimuli from the orthographic awareness and spelling tests in both English and Russian, listed in its appendices.

Finally, for parents and Russian speaking professionals, there’s an excellent article entitled, “Дислексия” in which Dr. Grigorenko comprehensively discusses the state of the field in Russian including information on its causes, rehabilitation, etc.

It’s All Due to …Language: How Subtle Symptoms Can Cause Serious Academic Deficits

Scenario: Len is a 7-2-year-old, 2nd-grade student who struggles with reading and writing in the classroom. He is very bright and has a high average IQ, yet when he is speaking he frequently can’t get his point across to others due to excessive linguistic reformulations and word-finding difficulties. The problem is that Len passed all the typical educational and language testing with flying colors, receiving average scores across the board on various tests including the Woodcock-Johnson Fourth Edition (WJ-IV) and the Clinical Evaluation of Language Fundamentals-5 (CELF-5). Stranger still is the fact that he aced Comprehensive Test of Phonological Processing, Second Edition (CTOPP-2), with flying colors, so he is not even eligible for a “dyslexia” diagnosis. Len is clearly struggling in the classroom with coherently expressing self, telling stories, understanding what he is reading, as well as putting his thoughts on paper. His parents have compiled impressively huge folders containing examples of his struggles. Yet because of his performance on the basic standardized assessment batteries, Len does not qualify for any functional assistance in the school setting, despite being virtually functionally illiterate in second grade.

The truth is that Len is quite a familiar figure to many SLPs, who at one time or another have encountered such a student and asked for guidance regarding the appropriate accommodations and services for him on various SLP-geared social media forums. But what makes Len such an enigma, one may inquire? Surely if the child had tangible deficits, wouldn’t standardized testing at least partially reveal them?

Well, it all depends really, on what type of testing was administered to Len in the first place. A few years ago I wrote a post entitled: “What Research Shows About the Functional Relevance of Standardized Language Tests“.  What researchers found is that there is a “lack of a correlation between frequency of test use and test accuracy, measured both in terms of sensitivity/specificity and mean difference scores” (Betz et al, 2012, 141). Furthermore, they also found that the most frequently used tests were the comprehensive assessments including the Clinical Evaluation of Language Fundamentals and the Preschool Language Scale as well as one-word vocabulary tests such as the Peabody Picture Vocabulary Test”. Most damaging finding was the fact that: “frequently SLPs did not follow up the comprehensive standardized testing with domain-specific assessments (critical thinking, social communication, etc.) but instead used the vocabulary testing as a second measure”.(Betz et al, 2012, 140)

In other words, many SLPs only use the tests at hand rather than the RIGHT tests aimed at identifying the student’s specific deficits. But the problem doesn’t actually stop there. Due to the variation in psychometric properties of various tests, many children with language impairment are overlooked by standardized tests by receiving scores within the average range or not receiving low enough scores to qualify for services.

Thus, “the clinical consequence is that a child who truly has a language impairment has a roughly equal chance of being correctly or incorrectly identified, depending on the test that he or she is given.” Furthermore, “even if a child is diagnosed accurately as language impaired at one point in time, future diagnoses may lead to the false perception that the child has recovered, depending on the test(s) that he or she has been given (Spaulding, Plante & Farinella, 2006, 69).”

There’s of course yet another factor affecting our hypothetical client and that is his relatively young age. This is especially evident with many educational and language testing for children in the 5-7 age group. Because the bar is set so low, concept-wise for these age-groups, many children with moderate language and literacy deficits can pass these tests with flying colors, only to be flagged by them literally two years later and be identified with deficits, far too late in the game.  Coupled with the fact that many SLPs do not utilize non-standardized measures to supplement their assessments, Len is in a pretty serious predicament.

But what if there was a do-over? What could we do differently for Len to rectify this situation? For starters, we need to pay careful attention to his deficits profile in order to choose appropriate tests to evaluate his areas of needs. The above can be accomplished via a number of ways. The SLP can interview Len’s teacher and his caregiver/s in order to obtain a summary of his pressing deficits. Depending on the extent of the reported deficits the SLP can also provide them with a referral checklist to mark off the most significant areas of need.

In Len’s case, we already have a pretty good idea regarding what’s going on. We know that he passed basic language and educational testing, so in the words of Dr. Geraldine Wallach, we need to keep “peeling the onion” via the administration of more sensitive tests to tap into Len’s reported areas of deficits which include: word-retrieval, narrative production, as well as reading and writing.

For that purpose, Len is a good candidate for the administration of the Test of Integrated Language and Literacy (TILLS), which was developed to identify language and literacy disorders, has good psychometric properties, and contains subtests for assessment of relevant skills such as reading fluency, reading comprehension, phonological awareness,  spelling, as well as writing  in school-age children.

Given Len’s reported history of narrative production deficits, Len is also a good candidate for the administration of the Social Language Development Test Elementary (SLDTE). Here’s why. Research indicates that narrative weaknesses significantly correlate with social communication deficits (Norbury, Gemmell & Paul, 2014). As such, it’s not just children with Autism Spectrum Disorders who present with impaired narrative abilities. Many children with developmental language impairment (DLD) (#devlangdis) can present with significant narrative deficits affecting their social and academic functioning, which means that their social communication abilities need to be tested to confirm/rule out presence of these difficulties.

However, standardized tests are not enough, since even the best-standardized tests have significant limitations. As such, several non-standardized assessments in the areas of narrative production, reading, and writing, may be recommended for Len to meaningfully supplement his testing.

Let’s begin with an informal narrative assessment which provides detailed information regarding microstructural and macrostructural aspects of storytelling as well as child’s thought processes and socio-emotional functioning. My nonstandardized narrative assessments are based on the book elicitation recommendations from the SALT website. For 2nd graders, I use the book by Helen Lester entitled Pookins Gets Her Way. I first read the story to the child, then cover up the words and ask the child to retell the story based on pictures. I read the story first because: “the model narrative presents the events, plot structure, and words that the narrator is to retell, which allows more reliable scoring than a generated story that can go in many directions” (Allen et al, 2012, p. 207).

As the child is retelling his story I digitally record him using the Voice Memos application on my iPhone, for a later transcription and thorough analysis.  During storytelling, I only use the prompts: ‘What else can you tell me?’ and ‘Can you tell me more?’ to elicit additional information. I try not to prompt the child excessively since I am interested in cataloging all of his narrative-based deficits. After I transcribe the sample, I analyze it and make sure that I include the transcription and a detailed write-up in the body of my report, so parents and professionals can see and understand the nature of the child’s errors/weaknesses.

Now we are ready to move on to a brief nonstandardized reading assessment. For this purpose, I often use the books from the Continental Press series entitled: Reading for Comprehension, which contains books for grades 1-8.  After I confirm with either the parent or the child’s teacher that the selected passage is reflective of the complexity of work presented in the classroom for his grade level, I ask the child to read the text.  As the child is reading, I calculate the correct number of words he reads per minute as well as what type of errors the child is exhibiting during reading.  Then I ask the child to state the main idea of the text, summarize its key points as well as define select text embedded vocabulary words and answer a few, verbally presented reading comprehension questions. After that, I provide the child with accompanying 5 multiple choice question worksheet and ask the child to complete it. I analyze my results in order to determine whether I have accurately captured the child’s reading profile.

Finally, if any additional information is needed, I administer a nonstandardized writing assessment, which I base on the Common Core State Standards for 2nd grade. For this task, I provide a student with a writing prompt common for second grade and give him a period of 15-20 minutes to generate a writing sample. I then analyze the writing sample with respect to contextual conventions (punctuation, capitalization, grammar, and syntax) as well as story composition (overall coherence and cohesion of the written sample).

The above relatively short assessment battery (2 standardized tests and 3 informal assessment tasks) which takes approximately 2-2.5 hours to administer, allows me to create a comprehensive profile of the child’s language and literacy strengths and needs. It also allows me to generate targeted goals in order to begin effective and meaningful remediation of the child’s deficits.

Children like Len will, unfortunately, remain unidentified unless they are administered more sensitive tasks to better understand their subtle pattern of deficits. Consequently, to ensure that they do not fall through the cracks of our educational system due to misguided overreliance on a limited number of standardized assessments, it is very important that professionals select the right assessments, rather than the assessments at hand, in order to accurately determine the child’s areas of needs.

Making Our Interventions Count or What’s Research Got To Do With It?

Image result for effective interventionTwo years ago I wrote a blog post entitled: “What’s Memes Got To Do With It?” which summarized key points of Dr. Alan G. Kamhi’s 2004 article: “A Meme’s Eye View of Speech-Language Pathology“. It delved into answering the following question: “Why do some terms, labels, ideas, and constructs [in our field] prevail whereas others fail to gain acceptance?”.

Today I would like to reference another article by Dr. Kamhi written in 2014, entitled “Improving Clinical Practices for Children With Language and Learning Disorders“.

This article was written to address the gaps between research and clinical practice with respect to the implementation of EBP for intervention purposes.

Dr. Kamhi begins the article by posing 10 True or False questions for his readers:

  1. Learning is easier than generalization.
  2. Instruction that is constant and predictable is more effective than instruction that varies the conditions of learning and practice.
  3. Focused stimulation (massed practice) is a more effective teaching strategy than varied stimulation (distributed practice).
  4. The more feedback, the better.
  5. Repeated reading of passages is the best way to learn text information.
  6. More therapy is always better.
  7. The most effective language and literacy interventions target processing limitations rather than knowledge deficits.
  8. Telegraphic utterances (e.g., push ball, mommy sock) should not be provided as input for children with limited language.
  9. Appropriate language goals include increasing levels of mean length of utterance (MLU) and targeting Brown’s (1973) 14 grammatical morphemes.
  10. Sequencing is an important skill for narrative competence.

Guess what? Only statement 8 of the above quiz is True! Every other statement from the above is FALSE!

Now, let’s talk about why that is!

First up is the concept of learning vs. generalization. Here Dr. Kamhi discusses that some clinicians still possess an “outdated behavioral view of learning” in our field, which is not theoretically and clinically useful. He explains that when we are talking about generalization – what children truly have a difficulty with is “transferring narrow limited rules to new situations“. “Children with language and learning problems will have difficulty acquiring broad-based rules and modifying these rules once acquired, and they also will be more vulnerable to performance demands on speech production and comprehension (Kamhi, 1988)” (93). After all, it is not “reasonable to expect children to use language targets consistently after a brief period of intervention” and while we hope that “language intervention [is] designed to lead children with language disorders to acquire broad-based language rules” it is a hugely difficult task to undertake and execute.

Next, Dr. Kamhi addresses the issue of instructional factors, specifically the importance of “varying conditions of instruction and practice“.  Here, he addresses the fact that while contextualized instruction is highly beneficial to learners unless we inject variability and modify various aspects of instruction including context, composition, duration, etc., we ran the risk of limiting our students’ long-term outcomes.

After that, Dr. Kamhi addresses the concept of distributed practice (spacing of intervention) and how important it is for teaching children with language disorders. He points out that a number of recent studies have found that “spacing and distribution of teaching episodes have more of an impact on treatment outcomes than treatment intensity” (94).

He also advocates reducing evaluative feedback to learners to “enhance long-term retention and generalization of motor skills“. While he cites research from studies pertaining to speech production, he adds that language learning could also benefit from this practice as it would reduce conversational disruptions and tunning out on the part of the student.

From there he addresses the limitations of repetition for specific tasks (e.g., text rereading). He emphasizes how important it is for students to recall and retrieve text rather than repeatedly reread it (even without correction), as the latter results in a lack of comprehension/retention of read information.

After that, he discusses treatment intensity. Here he emphasizes the fact that higher dose of instruction will not necessarily result in better therapy outcomes due to the research on the effects of “learning plateaus and threshold effects in language and literacy” (95). We have seen research on this with respect to joint book reading, vocabulary words exposure, etc. As such, at a certain point in time increased intensity may actually result in decreased treatment benefits.

His next point against processing interventions is very near and dear to my heart. Those of you familiar with my blog know that I have devoted a substantial number of posts pertaining to the lack of validity of CAPD diagnosis (as a standalone entity) and urged clinicians to provide language based vs. specific auditory interventions which lack treatment utility. Here, Dr. Kamhi makes a great point that: “Interventions that target processing skills are particularly appealing because they offer the promise of improving language and learning deficits without having to directly target the specific knowledge and skills required to be a proficient speaker, listener, reader, and writer.” (95) The problem is that we have numerous studies on the topic of improvement of isolated skills (e.g., auditory skills, working memory, slow processing, etc.) which clearly indicate lack of effectiveness of these interventions.  As such, “practitioners should be highly skeptical of interventions that promise quick fixes for language and learning disabilities” (96).

Now let us move on to language and particularly the models we provide to our clients to encourage greater verbal output. Research indicates that when clinicians are attempting to expand children’s utterances, they need to provide well-formed language models. Studies show that children select strong input when its surrounded by weaker input (the surrounding weaker syllables make stronger syllables stand out).  As such, clinicians should expand upon/comment on what clients are saying with grammatically complete models vs. telegraphic productions.

From there lets us take a look at Dr. Kamhi’s recommendations for grammar and syntax. Grammatical development goes much further than addressing Brown’s morphemes in therapy and calling it a day. As such, it is important to understand that children with developmental language disorders (DLD) (#DevLang) do not have difficulty acquiring all morphemes. Rather studies have shown that they have difficulty learning grammatical morphemes that reflect tense and agreement  (e.g., third-person singular, past tense, auxiliaries, copulas, etc.). As such, use of measures developed by (e.g., Tense Marker Total & Productivity Score) can yield helpful information regarding which grammatical structures to target in therapy.

With respect to syntax, Dr. Kamhi notes that many clinicians erroneously believe that complex syntax should be targeted when children are much older. The Common Core State Standards do not help this cause further, since according to the CCSS complex syntax should be targeted 2-3 grades, which is far too late. Typically developing children begin developing complex syntax around 2 years of age and begin readily producing it around 3 years of age. As such, clinicians should begin targeting complex syntax in preschool years and not wait until the children have mastered all morphemes and clauses (97)

Finally, Dr. Kamhi wraps up his article by offering suggestions regarding prioritizing intervention goals. Here, he explains that goal prioritization is affected by

  • clinician experience and competencies
  • the degree of collaboration with other professionals
  • type of service delivery model
  • client/student factors

He provides a hypothetical case scenario in which the teaching responsibilities are divvied up between three professionals, with SLP in charge of targeting narrative discourse. Here, he explains that targeting narratives does not involve targeting sequencing abilities. “The ability to understand and recall events in a story or script depends on conceptual understanding of the topic and attentional/memory abilities, not sequencing ability.”  He emphasizes that sequencing is not a distinct cognitive process that requires isolated treatment. Yet many SLPs “continue to believe that  sequencing is a distinct processing skill that needs to be assessed and treated.” (99)

Dr. Kamhi supports the above point by providing an example of two passages. One, which describes a random order of events, and another which follows a logical order of events. He then points out that the randomly ordered story relies exclusively on attention and memory in terms of “sequencing”, while the second story reduces demands on memory due to its logical flow of events. As such, he points out that retelling deficits seemingly related to sequencing, tend to be actually due to “limitations in attention, working memory, and/or conceptual knowledge“. Hence, instead of targeting sequencing abilities in therapy, SLPs should instead use contextualized language intervention to target aspects of narrative development (macro and microstructural elements).

Furthermore, here it is also important to note that the “sequencing fallacy” affects more than just narratives. It is very prevalent in the intervention process in the form of the ubiquitous “following directions” goal/s. Many clinicians readily create this goal for their clients due to their belief that it will result in functional therapeutic language gains. However, when one really begins to deconstruct this goal, one will realize that it involves a number of discrete abilities including: memory, attention, concept knowledge, inferencing, etc.  Consequently, targeting the above goal will not result in any functional gains for the students (their memory abilities will not magically improve as a result of it). Instead, targeting specific language and conceptual goals  (e.g., answering questions, producing complex sentences, etc.) and increasing the students’ overall listening comprehension and verbal expression will result in improvements in the areas of attention, memory, and processing, including their ability to follow complex directions.

There you have it! Ten practical suggestions from Dr. Kamhi ready for immediate implementation! And for more information, I highly recommend reading the other articles in the same clinical forum, all of which possess highly practical and relevant ideas for therapeutic implementation. They include:

What Should be Driving Our Treatment?

Today  I want to talk treatment.  That thing that we need to plan for as we are doing our assessments.   But are we starting our treatments the right way? The answer may surprise you. I often see SLPs phrasing questions regarding treatment the following way: “I have a student diagnosed with ____ (insert disorder here). What is everyone using (program/app/materials) during therapy sessions to address ___ diagnosis?”

Of course, the answer is never that simple. Just because a child has a diagnosis of a social communication disorder, word-finding deficits, or a reading disability does not automatically indicate to the treating clinician, which ‘cookie cutter’ materials and programs are best suited for the child in question. Only a profile of strengths and needs based on a comprehensive language and literacy testing can address this in an adequate and targeted manner.

To illustrate,  reading intervention is a much debated and controversial topic nowadays. Everywhere you turn there’s a barrage of advice for clinicians and parents regarding which program/approach to use. Barton, Wilson, OG… the well-intentioned advice just keeps on coming. The problem is that without knowing the child’s specific deficit areas, the application of the above approaches is quite frankly … pointless.

There could be endless variations of how deficits manifest in poor readers. Is it aspects of phonological awareness, phonics, morphology, etc. What combination of deficits is preventing the child from becoming a good reader?

Let’s a take a look at an example, below. It’s the CTOPP-2 results of a 7-6-year-old female with a documented history of extensive reading difficulties and a significant family history of reading disabilities in the family.

Results of the Comprehensive Test of Phonological Processing-2 (CTOPP-2)

Subtests Scaled Scores Percentile Ranks Description
Elision (EL) 7 16 Below Average
Blending Words (BW) 13 84 Above Average
Phoneme Isolation (PI) 6 9 Below Average
Memory for Digits (MD) 8 25 Average
Nonword Repetition (NR) 8 25 Average
Rapid Digit Naming (RD) 10 50 Average
Rapid Letter Naming (RL) 11 63 Average
Blending Nonwords (BN) 8 25 Average
Segmenting Nonwords (SN) 8 25 Average

However, the results of her CTOPP-2 testing clearly indicate that phonological awareness, despite two areas of mild weaknesses, is not really a significant problem for this child.  So let’s look at the student’s reading fluency results.

Reading Fluency: “LG’s reading fluency during this task was judged to be significantly affected by excessive speed, inappropriate pausing, word misreadings, choppy prosody, as well as inefficient word attack skills.  While she was able to limitedly utilize the phonetic spelling of unfamiliar words (e.g., __) provided to her in parenthesis next to the word (which she initially misread as ‘__’), she exhibited limited use of metalinguistic strategies (e.g., pre-scanning sentences to aid text comprehension, self-correcting to ensure that the read words made sense in the context of the sentence, etc.), when reading the provided passage. To illustrate, during the reading of the text, LG was observed to frequently (at least 3 times) lose her place and skip entire lines of text without any attempts at self-correction. At times she was observed to read the same word a number of different ways (e.g., read ‘soup’ as ‘soup’ then as ‘soap’,  ‘roots’ as ‘roofs’ then as ‘roots’, etc.) without attempting to self-correct. LG’s oral reading rate was also observed to be impaired for her age/grade levels. Her prosody was significantly adversely affected due to lack of adequate pausing for punctuation marks (e.g., periods, commas, etc.).  Instead, she paused during text reading only when he could not decode select words in the text.  Though, LG was able to read 70 words per minute, which was judged to be grossly commensurate with grade-level, out of these 70 words she skipped 2 entire lines of text, invented an entire line of text, as well as made 4 decoding errors and 6 inappropriate pauses.”

So now we know that despite quite decent phonological awareness abilities, this student presents with quite poor sound-letter correspondence skills and will definitely benefit from explicit phonics instruction addressing the above deficit areas. But that is only the beginning!   By looking at the analysis of specific misreadings we next need to determine what other literacy areas need to be addressed. For the sake of brevity, I can specify that further analysis of this child reading abilities revealed that reading comprehension, orthographic knowledge, as well as morphological awareness were definitely areas that also required targeted remediation. The assessment also revealed that the child presented with poor spelling and writing abilities, which also needed to be addressed in the context of therapy.

Now, what if I also told you that this child had already been receiving private, Orton-Gillingham reading instruction for a period of  2 years, 1x per week, at the time the above assessment took place? Would you change your mind about the program in question? 

Well, the answer is again not so simple! OG is a fine program, but as you can see from the above example it has definite limitations and is not an exclusive fit for this child, or for any child for that matter. Furthermore, a solidly-trained in literacy clinician DOES NOT need to rely on just one program to address literacy deficits. They simply need solid knowledge of typical and atypical language and literacy development/milestones and know how to create a targeted treatment hierarchy in order to deliver effective intervention services. But for that, they need to first, thoughtfully, construct assessment-based treatment goals by carefully taking into the consideration the child’s strengths and needs.

So let’s stop asking which approach/program we should use and start asking about the child’s profile of strengths and needs in order to create accurate language and literacy goals based on solid evidence and scientifically-guided treatment practices.

The Importance of Narrative Assessments in Speech Language Pathology (Revised)

Unconscious Bias: The Power and Risks of Societal Narratives | by Phillip  Yan | Left | Right | MediumAs SLPs we routinely administer a variety of testing batteries in order to assess our students’ speech-language abilities. Grammar, syntax, vocabulary, and sentence formulation get frequent and thorough attention. But how about narrative production? Does it get its fair share of attention when the clinicians are looking to determine the extent of the child’s language deficits? I was so curious about what the clinicians across the country were doing that in 2013, I created a survey and posted a link to it in several SLP-related FB groups.  I wanted to find out how many SLPs were performing narrative assessments, in which settings, and with which populations.  From those who were performing these assessments, I wanted to know what type of assessments were they using and how they were recording and documenting their findings.   Since the purpose of this survey was non-research based (I wasn’t planning on submitting a research manuscript with my findings), I only analyzed the first 100 responses (the rest were very similar in nature) which came my way, in order to get the general flavor of current trends among clinicians, when it came to narrative assessments. Here’s a brief overview of my [limited] findings. Continue reading The Importance of Narrative Assessments in Speech Language Pathology (Revised)

Treatment of Children with “APD”: What SLPs Need to Know

Free stock photo of people, woman, cute, playingIn recent years there has been an increase in research on the subject of diagnosis and treatment of Auditory Processing Disorders (APD), formerly known as Central Auditory Processing Disorders or CAPD.

More and more studies in the fields of audiology and speech-language pathology began confirming the lack of validity of APD as a standalone (or useful) diagnosis. To illustrate, in June 2015, the American Journal of Audiology published an article by David DeBonis entitled: “It Is Time to Rethink Central Auditory Processing Disorder Protocols for School-Aged Children.” In this article, DeBonis pointed out numerous inconsistencies involved in APD testing and concluded that “routine use of APD test protocols cannot be supported” and that [APD] “intervention needs to be contextualized and functional” (DeBonis, 2015, p. 124) Continue reading Treatment of Children with “APD”: What SLPs Need to Know

A Focus on Literacy

Image result for literacyIn recent months, I have been focusing more and more on speaking engagements as well as the development of products with an explicit focus on assessment and intervention of literacy in speech-language pathology. Today I’d like to introduce 4 of my recently developed products pertinent to assessment and treatment of literacy in speech-language pathology.

First up is the Comprehensive Assessment and Treatment of Literacy Disorders in Speech-Language Pathology

which describes how speech-language pathologists can effectively assess and treat children with literacy disorders, (reading, spelling, and writing deficits including dyslexia) from preschool through adolescence.  It explains the impact of language disorders on literacy development, lists formal and informal assessment instruments and procedures, as well as describes the importance of assessing higher order language skills for literacy purposes. It reviews components of effective reading instruction including phonological awareness, orthographic knowledge, vocabulary awareness,  morphological awareness, as well as reading fluency and comprehension. Finally, it provides recommendations on how components of effective reading instruction can be cohesively integrated into speech-language therapy sessions in order to improve literacy abilities of children with language disorders and learning disabilities.

from wordless books to readingNext up is a product entitled From Wordless Picture Books to Reading Instruction: Effective Strategies for SLPs Working with Intellectually Impaired StudentsThis product discusses how to address the development of critical thinking skills through a variety of picture books utilizing the framework outlined in Bloom’s Taxonomy: Cognitive Domain which encompasses the categories of knowledge, comprehension, application, analysis, synthesis, and evaluation in children with intellectual impairments. It shares a number of similarities with the above product as it also reviews components of effective reading instruction for children with language and intellectual disabilities as well as provides recommendations on how to integrate reading instruction effectively into speech-language therapy sessions.

Improving critical thinking via picture booksThe product Improving Critical Thinking Skills via Picture Books in Children with Language Disorders is also available for sale on its own with a focus on only teaching critical thinking skills via the use of picture books.

Best Practices in Bilingual LiteracyFinally,   my last product Best Practices in Bilingual Literacy Assessments and Interventions focuses on how bilingual speech-language pathologists (SLPs) can effectively assess and intervene with simultaneously bilingual and multicultural children (with stronger academic English language skills) diagnosed with linguistically-based literacy impairments. Topics include components of effective literacy assessments for simultaneously bilingual children (with stronger English abilities), best instructional literacy practices, translanguaging support strategies, critical questions relevant to the provision of effective interventions, as well as use of accommodations, modifications and compensatory strategies for improvement of bilingual students’ performance in social and academic settings.

You can find these and other products in my online store (HERE).
