Comorbidity in Reading Comprehension and Word-Problem Solving Difficulties: Exploring Shared Risk Factors and Their Impact on Language Minority Learners

The purpose of this study was threefold: to examine unique and shared risk factors of comorbidity for reading comprehension and word-problem solving difficulties, to explore whether language minority (LM) learners are at increased risk of what we refer to as higher order comorbidity (reading comprehension and word-problem solving difficulties), and to examine the profiles of at-risk LM learners compared with at-risk non-LM learners. At-risk (LM n = 70; non-LM n = 89) and not-at-risk (LM n = 44; non-LM n = 114) students were evaluated on foundational academic (word reading, calculation), behavioral (behavioral attention), cognitive (working memory, processing speed, nonverbal reasoning), and language (vocabulary, listening comprehension) measures in English. Results indicated listening comprehension was the only shared risk factor for higher order comorbidity. Furthermore, LM learners were 3 times more likely to be identified as at-risk compared with non-LM learners. Finally, among at-risk learners, no differences were found on cognitive dimensions by language status, but LM learners had lower reading and listening comprehension skills than non-LM learners, with a relative advantage in behavioral attention. Results have implications for understanding higher order comorbidity and for developing methods to identify and intervene with higher order comorbidity among the growing population of LM learners.

Co-Occurrence of Reading and Writing Difficulties: The Application of the Interactive Dynamic Literacy Model

This article presents the application of the interactive dynamic literacy (IDL) model (Kim, 2020a) toward understanding difficulties in learning to read and write. According to the IDL model, reading and writing are part of communicative acts that draw on largely shared processes and skills as well as unique processes and skills. As such, reading and writing are dissociable but interdependent systems that have hierarchical, interactive, and dynamic relations. These key tenets of the IDL model are applied to the disruption of reading and writing development to explain co-occurrence of reading–writing difficulties using a single framework. The following hypotheses are presented: (a) co-occurrence between word reading and spelling and handwriting difficulties; (b) co-occurrence of dyslexia with written composition difficulties; (c) co-occurrence between reading comprehension and written composition difficulties; (d) co-occurrence of language difficulties with reading difficulties and writing difficulties; (e) co-occurrence of reading, writing, and language difficulties with weak domain-general skills or executive functions such as working memory and attentional control (including attention-deficit hyperactivity disorder [ADHD]); and (f) multiple pathways for reading and writing difficulties. Implications are discussed.

Sustaining the Use of Evidence-Based Tier 1 Literacy Practices That Benefit Students With Disabilities

The adoption and sustainability of evidence-based Tier 1 literacy practices in secondary content-area classes is important to improve the reading success among students with learning disabilities. We conducted an exploratory multiple-case study investigating teachers’ adoption and sustained use of evidence-based Tier 1 literacy practices that benefit students with learning disabilities. The study was conducted within the context of an adolescent literacy model demonstration project funded by the Office of Special Education Programs (i.e., Promoting Adolescents’ Comprehension of Text [PACT] Plus). Interviews were conducted with two administrators and seven teachers who sustained implementation of the PACT practices beyond 1 year of researcher support. Analyses revealed practice and school-level factors that influenced teachers’ sustained use of the practices. We used findings from this study to propose a model of sustainability of Tier 1 evidence-based literacy practices used to improve outcomes for students with learning disabilities. Limitations and implications for future research are provided.

International Perspectives on Spelling and Writing in Different Orthographies: Introduction to the Special Series

This article serves as an introduction to the special issue on spelling and writing in different orthographies. Most studies and theoretical models of writing are based on the English language, and it is generally assumed that what is true for English is also true for other languages. Further, there are more studies on reading compared to studies of writing and spelling. Considering that 80% of the world’s population speaks a language other than English, we need more studies on writing and spelling in languages other than English. With this intention, we are presenting 6 papers on writing and spelling in different languages of different orthographic depth, from highly transparent orthographies like Spanish and Italian to highly opaque orthography like Cantonese.

Phonological Processing, Visuospatial Skills, and Pattern Understanding in Chinese Developmental Dyscalculia

A number of previous studies have identified cognitive deficits in developmental dyscalculia (DD). Yet, most of these studies were in alphabetic languages, whereas few of them examined Chinese DD. Here, we conducted a study aiming to determine the cognitive factors associated with DD in Chinese children. Five candidate cognitive factors of DD—phonological retrieval, phonological awareness, visual–spatial attention, spatial thinking, and pattern understanding—were studied in the present study. A total of 904 Chinese children aged between 8 and 11 years participated in this study. From the sample, 97 children were identified with DD through tests of arithmetic ability, and 93 age and IQ–matched typically developing children were selected as controls. Logistic regression analysis revealed that phonological retrieval, pattern understanding, visual–spatial attention, and phonological awareness significantly predicted DD, whereas spatial thinking failed to do so. Results of logistic relative weights analysis showed that all five factors explained statistically significant amounts of variance in arithmetic scores. Phonological retrieval had the most influence on DD, followed by pattern understanding, visual–spatial attention, phonological awareness, and spatial thinking. These findings have important clinical implications for diagnosis and intervention of Chinese DD.

Using Spelling Error Analyses to Examine Individual Differences in German Students From Diverse Linguistic Backgrounds: A Latent Class Approach

The current study examined German spelling errors among students with German as their first (L1) and those with German as their second language (L2) in Grades 3–4 (elementary school students; n = 127) and Grades 5–7 (secondary school students; n = 379). Five hundred and six students participated in the study. We performed two separate latent class analyses on elementary and secondary school students. Results indicate that elementary school students can be categorized as good (Class 1), consonant error dominant (Class 2), or poor spellers (Class 3). However, secondary students can be categorized as addition and sequence error dominant (Class 1), substitution and omission error dominant (Class 2), or poor spellers (Class 3). The three-step multinomial logistic regression analyses suggested that decoding was associated with the highest chances of being poor spellers in both elementary and secondary schools. Speaking German as L1 or L2 was a significant predictor of heterogeneities in secondary but not elementary school students. Polish L1 secondary students had the highest possibility of being poor spellers. The results suggest heterogeneities of student profiles. In addition, special attention should be given to secondary school students with the Polish L1 background in their spelling struggles associated with German orthography.

Special Education Services and School-Related Quality of Life in Children With Learning Disorders and Their Families: A One-Year Follow-Up Study

Learning disorders can have adverse impacts on children and families extending beyond the academic skills deficits. The goal of the present study was to assess the impact of the school’s response, following an independent evaluation, for child and family school-related quality of life (QOL). We hypothesized that a positive school response would be associated with improved QOL. Parents completed the LDQOL/15, a brief measure of school-related QOL, at the time that their child received an independent evaluation and again a year later ( N =155). At follow-up, parents reported the tenor of the school’s response to the evaluation and whether special education services had changed. QOL problems were very high in this referred population, with 66% of respondents rating a level of problems in the clinical range at baseline. Predicted interactions between time of assessment (baseline/follow-up) and the school’s response to the evaluation were confirmed for all outcome variables; a positive school response was associated with improved QOL. Nevertheless, the overall prevalence of school-related QOL problems remained high a year after the evaluation. These findings indicate that special education interventions can mitigate LD impacts, but even with these services, many children with learning disorders and their families continue to be significantly affected.

Effects of Varying Levels of Data Use to Intensify a Multisyllabic Word Reading Intervention for Upper Elementary Students With or At Risk for Reading Disabilities

For students who show inadequate response to research-based intervention, intensification of intervention using data-based decision making (DBDM) is recommended. There is a paucity of research on upper elementary students related to the efficacy of (a) word reading interventions and (b) DBDM procedures. This randomized controlled trial examined the differential effects of data use at two timepoints to intensify a multisyllabic word reading intervention for Grade 4 and 5 students with or at risk for reading disabilities (RD). Eighty-eight students were randomly assigned to one of three conditions: initial customization of the intervention (IC-only), initial customization with DBDM (IC + DBDM), or a business-as-usual comparison condition. Results indicated that (a) students in both treatment conditions outperformed the comparison condition on multisyllabic word reading and (b) students in the IC + DBDM condition also outperformed comparison students on decoding. Implications, including the use of DBDM in addition to IC-only as well as methods for decision-making within a small-group context, are discussed.

Learning Disabilities Elevate Children’s Risk for Behavioral-Emotional Problems: Differences Between LD Types, Genders, and Contexts

Our purpose was to study the frequency of behavioral-emotional problems among children identified with a learning disability (LD). The data comprised 579 Finnish children (8–15 years) with reading disability (RD-only), math disability (MD-only), or both (RDMD) assessed at a specialized clinic between 1985 and 2017. We analyzed percentages of children with behavioral-emotional symptoms reaching clinical range (i.e., z score ≥1.5 SDs) and the effects of the LD type, gender, and context (home vs. school) on them. Furthermore, we analyzed the effect of the severity of LD and gender on the amount of behavioral-emotional symptoms reported by teachers and parents. Alarmingly high percentages of children, irrespective of LD type, demonstrated behavioral-emotional problems: more than 37% in Affective, Anxiety, and Attention Deficit Hyperactivity Disorder (ADHD) problems. Contextual variation was large, as more problems were reported by teachers than by mothers. The unique effects of gender and LD type were rare, but the results raised concern for those with MD-only, especially boys. The results underscore the need to draw attention to the importance of assessing children with LD for behavioral-emotional problems and emphasize the importance of teachers’ awareness of behavioral-emotional problems among students with LD and cooperation among child, teacher, and parents in assessment and support planning.

Examining the Effects of Integrating Anxiety Management Instruction Within a Reading Intervention for Upper Elementary Students With Reading Difficulties

We present findings from the first cohort of third- and fourth-grade students with reading difficulties (128 students from 31 classrooms) who participated in a 2-year intervention examining the effects of a reading intervention with and without anxiety management. Using a randomized controlled trial, students were assigned to one of three conditions: (a) small-group reading intervention with anxiety management instruction (RANX), (b) small-group reading intervention with math fact practice (RMATH), and (c) business-as-usual (BAU) comparison condition (no researcher provided treatment). Personnel from the research team provided participants in the RANX and RMATH the same reading intervention with the variation in the two treatments being whether the same amount of time per lesson was allocated to anxiety management (RANX) or practicing math facts (RMATH). Students in the RANX significantly outperformed students in the BAU on reading comprehension (effect size [ES] = 1.22) and students in the RMATH outperformed BAU on reading comprehension (ES = 0.77). Groups did not differ significantly on other reading outcomes. Reading anxiety moderated the main effect of the RANX intervention on Test of Word Reading Efficiency (TOWRE) word reading when contrasted against the BAU group indicating a significant difference favoring RANX where treatment’s effect decreased by 0.94 units (about 1 point on the outcome) on word reading for each additional point increase in reading anxiety.
