Function-based interventions for LD?

Most readers are likely familiar with the idea that one can, by carefully assessing the antecedents and consequences of a problem behavior, essentially determine what is causing that problem behavior to occur. Given that at least some—many?—students with Learning Disabilities (LD) have some problem-some behaviors, wouldn’t it be cool if there was an evidence base about using functional analysis techniques to document development of procedures for addressing the problem behaviors of students with LD?

In “A Systematic Review of Function-Based Interventions for Students with Learning Disabilities,” Professor John McKenna and his colleagues examined the research literature in search of that very evidence base. They were able to locate only a few studies that met the most rigorous standards, but those studies allowed them to conclude that this idea is a promising one. Here’s the source and the abstract with a hot DOI. I think the publisher (Wiley) may be allowing public access to the entire article, so try clicking on the PDF to download it. (I can’t tell, ’cause I’m working from my office, which has free access anyway; drop a comment to let me know.)

McKenna, J. W., Flower, A., Kim, M. K., Ciullo, S., & Haring, C. (2015). A systematic review of function-based interventions for students with learning disabilities. Learning Disabilities Research & Practice, 30, 15-28. DOI:10.1111/ldrp.12049

Students with learning disabilities (LD) experience pervasive academic deficits requiring extensive academic intervention; however, they may also engage in problem behaviors that adversely affect teaching and learning, thus lessening the potential impact of specialized instruction and supports. The learning deficits of students with LD are prevalent in the extant research, but behavioral needs appear to receive less attention. The authors report the results of a systematic review investigating the evidence-base for function-based interventions for students with LD using the What Works Clearinghouse (WWC) criteria for evaluating single-case studies. Fourteen studies with 17 participants met inclusion criteria, with the majority occurring in elementary settings. Although interventions tended to be effective, few included maintenance and generalization measures. Because of the small number of studies (n = 4) that met WWC design and effectiveness standards, the authors conclude that function-based interventions, although promising, cannot currently be considered an evidence-based practice for students with LD. Implications for practice, areas for future research, and study limitations are reported.

Block those bullies

As the beginning of school approaches, many schools will be considering what to do about bullying, a problem the plagues many students with Learning Disabilities (LD). But, what do we know about the connections between special ed and bullying? Can bullying mess up a student’s IEP? Here’s a little background and some suggested resources.

As one might suspect, one of the difficulties for students with LD is that they are perceived as victims of bullies. Nabuzoka and Smith’s (1993) analysis of sociometric data from ~180 pre-adolescent students, about 20% of whom had LD, showed that those with LD were more likely to be victims of bullying than their non-disabled peers, despite not being judged more aggressive. Estell et al. (2009) reported that teachers considered fifth-grade students with high-incidence disabilities likely to be victims of bullies. However, both teachers and the students’ peers rated them to as likely to be bullies. Those students with disabilities who behaved aggressively were the ones who were more likely to be nominated as bullies.

Subtyping LD

Have you been hearing a lot about subtypes of LD lately? Perhaps it’s just that I’ve been especially alert to it, but it seems I’ve heard a lot of mentions about subtypes of Learning Disabilities in the last few weeks. I want to write a longer, more thorough discussion of the topic, but I’ve found myself repeating a few foundational comments, so I thought I ought to post them here and let others have a go at them.

First, the idea of subtypes of LD is essentially a given. It has to do with the heterogeneity of LD. Because LD is essentially an umbrella category for a diverse array of learning disabilities (note the plural), there are bound to be subgroups. Some students will have problems primarily with reading, some primarily with arithmetic and mathematics, some with writing, others with combinations of these. That makes for lots of subgroups right there. That is, one could start with dyslexia, dyscalculia, and dysgraphia!

Reading comprehension help for ADHD high schoolers

In “Improving the Reading Recall of High School Students With ADHD,” Joseph W. Johnson, Robert Reid, and Linda H. Mason report the results of an intensive study in which they examined the effects of teaching high-school students a comprehension strategy as a part of a self-regulated strategy development model. They found that systematically preparing the students to use what they dubbed the “Think Before Reading” (TWA) strategy helped the students with recall of passages’ main ideas and details connected to them.

Students with attention-deficit/hyperactivity disorder (ADHD) often have difficulty with reading comprehension. This multiple baseline across participants design with multiple probes study examined the effectiveness of a multicomponent reading comprehension strategy (TWA: Think Before Reading, Think While Reading, Think After Reading) taught following the self-regulated strategy development model on social studies expository text recall of three high school students with ADHD. Results showed improvement in the number of main ideas and percentage of supporting details recalled. Gains were maintained and some improvement occurred at 2- and 4-week follow-ups. Implications for future research and practice are discussed.

LearningRx in the popular press

Sandy Hausman, Charlottesville (VA, US) reporter for WVTF (one of the local public radio stations available in my listening area), carried a story about LearningRx and Learning Disabilities this morning. Unlike the credible coverage provided by many reporters for popular-but-unproven therapies for LD and other disorders, Ms. Hausman provided a sensible and balanced story about LearningRx. Here’s the blurb from WVTF’s Web site

Americans spend millions of dollars keeping our bodies in shape. Now a Charlottesville man is offering a workout for the brain. His center–part of a nationwide franchise–promises to help children and adults improve their concentration, memory, reasoning, and other mental skills. Sandy Hausman has the story.

Unlike many reporters who too-often fall for pop-psych and pop-ed theories (as regularly noted in other posts here on LD Blog), Ms. Hausman gets many facts right (e.g., prevalence of LD), phrases her report carefully (describes LearningRx reports as “internal studies”), includes appropriate caveats along with personal-interest angles, and even incorporates alternative explanations from the experts she interviews.

This is an example of journalism done better. Listen to an MP3 of Ms. Hausman’s report and explore WVTF.org.

K. Ellison again

For those who haven’t been paying attention, Katherine Ellison has appeared on multiple media outlets promoting her book, Buzz. She had another entry, this time in the Washington Post yesterday (20 November 2010). Given the recent release of the US Centers for Disease Control prevalence study, this is pretty timely and, award-winning journalist that she is, Ms. Ellison notes the connection in her lead.

As the mother of a teenager who got a diagnosis of attention-deficit/hyperactivity disorder in 2004, I wasn’t surprised to read the new report from the Centers for Disease Control and Prevention that said the number of ADHD cases in children jumped by 22 percent between 2003 and 2007 – an increase of 1 million kids.

But, she goes on to add lots more good content to her op-ed piece published under the headline “Doing battle with the ADHD-industrial complex.”

DLD fall conference is just around the corner

Check out the fine slate of workshop sessions available to registered guests at the annual “Bridging the Gap Between Research and Practice” meeting of the Division for Learning Disabilities, which is to be held in Baltimore (MD, US) 29 and 30 October. Of course, I am biased, but I consider this one of the outstanding professional development opportunities of the year in learning disabilities, including the more specific disabilities such as dyslexia, dyscalculia, dysgraphia, and so forth (as well as related disorders such as attention-deficit hyperactivity disorder).

Does RtI reduce numbers of children in special education?

In an article slated to appear in Remedial and Special Education, Jeanne Wanzek and Sharon Vaughn reported that widely popular three-tiered approach to addressing did not significantly reduce the number and percentage of students identified for special education across seven elementary schools. Their study, which is limited to the response to instruction or intervention in the primary and early elementary grades and focused primarily on academic intervention, revealed no significant reduction in identification of children as having Learning Disabilities, even though this group would be the most likely to benefit from such prevention efforts. Similarly, there were no differences in the proportion of students identified for special education according to ethnic background.

Remediation changes brain structures

Writing in the journal Neuron, Timothy Keller and Marcel Just reported that they have found changes in children’s neural anatomy that appear to be a consequence of improved reading performance. Whereas previous studies, many of which I’ve mentioned in these posts, have shown changes in the blood flow in children’s brains as a consequence of reading instruction, the findings from Keller and Marcel showed that there are changes in the physical tissue in the brain following remedial reading instruction.

Promoting reading comprehension

Sheri Berkeley and colleagues reported the results of a meta-analysis of research on reading comprehension interventions for students with Learning Disabilities in a forthcoming issue of Remedial and Special Education. Although their results echo findings from earlier meta-analyses and narrative reviews, they were able to add refinements to educators’ understanding of ways to promote students’ understanding of what they read. They propose that the common element in successful interventions was “teach[ing] students to attend more carefully or to think more systematically about text as it was being read.”
