Investigating the Reading Profiles of Middle School Emergent Bilinguals with Significant Reading Comprehension Difficulties.

Purpose: This study investigated the reading profiles of middle school Spanish-speaking emergent bilinguals (EBs) with significantly below grade level reading comprehension and whether these profiles varied in their reading comprehension performance over time. Method: Latent profile analyses were used to classify Grade 6 and 7 Hispanic EBs (n = 340; 39% female) into subgroups based on their word reading and vocabulary knowledge. Growth models were then fit within each profile to evaluate reading comprehension performance over time. Results: Analyses revealed four latent profiles emerged: (a) very low word reading and low vocabulary (10%), (b) low word reading and low vocabulary (71%), (c) average word reading and low vocabulary (16%), and (d) high word reading and low vocabulary (3%). Subgroups varied in their reading comprehension initially and over one year. Students in the subgroup marked by very low word reading and low vocabulary showed the lowest reading comprehension performance initially; however, they also showed the greatest growth over one year. Conclusion: These findings suggest there is heterogeneity in the reading skill profiles of Spanish-speaking EBs with reading comprehension difficulties. They also underscore the prevalence of word reading difficulties among these students. These may be important factors to consider when developing interventions to prevent and remediate these difficulties.

Relationships Between Anxiety, Attention, and Reading Performance in Children.

Many studies link anxiety in children with reading difficulties, but some facets of anxiety have been found to be positively associated with reading achievement. Attentional Control Theory offers a potential explanation for these seemingly contradictory findings, positing that anxiety can both interfere in attentional processes and enhance effort and use of compensatory processing strategies. The current study examines the relationships between anxiety, attentional control, and reading performance (word reading/decoding and passage comprehension) in a racially-diverse sample of 251 s-grade students, 152 of whom had not met reading benchmarks using screening measures. Results showed that harm avoidance was positively associated with reading performance and physical symptoms of anxiety were negatively associated with reading performance. These links were attenuated when including attentional control in the model, suggesting mediation and lending support to Attentional Control Theory. Further research is needed to confirm causal mediation effects between anxiety, attentional control, and reading performance.

Internalizing Symptoms and Reading Difficulties Among Early Elementary School Students.

While the field of learning disabilities has grown substantially over the past several decades (Grigorenko et al. in Am Psychol 75:37, 2020) little work has explored the role of internalizing symptoms among struggling students. The present study compared struggling and typical readers on several child reported internalizing measures at both the beginning and end of a school year during which time they received either classroom-as-usual or research-team provided intensive intervention. Struggling readers who did and did not meet reading benchmarks were also compared at year-end. While minimal differences were present at the beginning of the year, numerous differences were observed at the end, with students exhibiting persistent reading struggles reporting significantly greater distress. Bi-directional associations emerged with beginning of year group status predicting internalizing symptoms and beginning of year internalizing symptoms predicting end of year intervention response group status. Findings are discussed in terms of future directions for enhancing intervention studies of struggling readers.

The Relative Effects of Instruction Linking Word Reading and Word Meaning Compared to Word Reading Instruction Alone on the Accuracy, Fluency, and Word Meaning Knowledge of 4th-5th Grade Students With Dyslexia.

This within-subjects experimental study investigated the relative effects of word reading and word meaning instruction (WR+WM) compared to word-reading instruction alone (WR) on the accuracy, fluency, and word meaning knowledge of 4th-5th graders with dyslexia. We matched word lists on syllables, phonemes, frequency, number of definitions, and concreteness. We assigned half the words to WR and half to WR+WM. Word reading accuracy, word reading fluency, and word meaning knowledge were measured at pretest, immediately following each intervention session, and at posttest, administered immediately following the 12, 45-minute, daily instructional sessions. Compared to WR instruction alone, WR+WM significantly improved accuracy (d = 0.65), fluency (d = 0.43), and word meaning knowledge (d = 1.92) immediately following intervention, and significantly improved accuracy (d = 0.74), fluency (d = 0.84), and word meaning knowledge (d = 1.03) at posttest. Findings support the premise that word meaning knowledge facilitates accurate and fluent word reading, and that instruction explicitly integrating word reading and word meaning may be an effective support for upper elementary students with dyslexia.

When Treatment Adherence Matters: Interactions Among Treatment Adherence, Instructional Quality, and Student Characteristics on Reading Outcomes.

In this study, we examined the extent to which teachers' treatment adherence, instructional quality, and the interaction of these variables influenced eighth-grade students' content knowledge and reading comprehension. We examined treatment fidelity for students (n = 775) in classes randomly assigned to receive an evidence-based content area reading program called Promoting Adolescents' Comprehension of Text. Results indicate that teachers' instructional quality was a statistically significant, positive predictor of student content knowledge and reading comprehension performance, whereas teachers' treatment adherence was not. Statistically significant interactions between treatment adherence and instructional quality were present, such that teachers' treatment adherence had a stronger impact on student learning outcomes when their overall instructional quality was low. Moderator analyses also revealed that students' pretest performance and English learner status influenced the effects of treatment adherence and instructional quality on student outcomes. These findings help elucidate the conditions under which Promoting Adolescents' Comprehension of Text leads to improved outcomes, and more broadly, underscore the importance of carefully examining dimensions of treatment fidelity when testing the effects of treatment programs.

Is the treatment weak or the test insensitive: Interrogating item difficulties to elucidate the nature of reading intervention effects.

Intervention research in education is sometimes criticized for the use of experimenter developed assessments, especially when these are over aligned with treatment. At the same time, intervention researchers sometimes prefer locally developed assessments because they appear to be more sensitive to treatment effects even when the test is not subject to the criticism of over alignment. This paper examines the question of test sensitivity to treatment effects for experimenter developed and standardized tests for the specific case of reading in grade 8. We examine similarities and differences between a specific experimenter developed test and widely used standardized reading assessment. Analyses show these particular tests to be quite comparable. The paper concludes with an examination of test sensitivity by simulating treatment effects of different magnitudes. These analyses highlight some potential limitations of the standardized test for detecting small to moderate effects depending on the ability range of the students participating in intervention. The implications for intervention research and identification of students under response to intervention are discussed.

Sustained attention and behavioral ratings of attention in struggling readers.

Attention is correlated with reading, but the extent to which behavioral ratings and sustained attention relate to reading skills is unclear. We assessed 245 4th and 5th grade struggling readers (mean age = 10.3 years) on behavioral ratings of attention, sustained attention, and reading over a school year. Contributions of behavioral ratings and sustained attention were considered cross-sectionally and longitudinally in the context of other important predictors of reading. Results suggest that sustained measures and behavioral ratings assess distinct, yet overlapping, aspects of attention. Both types of attention accounted for unique variance in comprehension, but not word reading accuracy or fluency, when evaluated cross-sectionally. Results also support the role of behavioral ratings of attention in fluency and in comprehension growth. Findings suggest that multidimensional assessment of attention is useful when considering its relation to reading, and highlights the need to integrate conceptualizations of attention that arise from different theoretical approaches.

Multitiered Systems of Support, Adaptive Interventions, and SMART Designs.

This article introduces the special section on adaptive interventions and sequential multiple-assignment randomized trial (SMART) research designs. In addition to describing the two accompanying articles, we discuss features of adaptive interventions (AIs) and describe the use of SMART design to optimize AIs in the context of multitiered systems of support (MTSS) and integrated MTSS. AI is a treatment delivery model that explicitly specifies how information about individuals should be used to decide which treatment to provide in practice. Principles that apply to the design of AIs may help to more clearly operationalize MTSS-based programs, improve their implementation in school settings, and increase their efficacy when used according to evidence-based decision rules. A SMART is a research design for developing and optimizing MTSS-based programs. We provide a running example of a SMART design to optimize an MTSS-aligned AI that integrates academic and behavioral interventions.

Current State of the Evidence: Examining the Effects of Orton-Gillingham Reading Interventions for Students With or at Risk for Word-Level Reading Disabilities.

Over the past decade, parent advocacy groups led a grassroots movement resulting in most states adopting dyslexia-specific legislation, with many states mandating the use of the Orton-Gillingham approach to reading instruction. Orton-Gillingham is a direct, explicit, multisensory, structured, sequential, diagnostic, and prescriptive approach to reading for students with or at risk for word-level reading disabilities (WLRD). Evidence from a prior synthesis and What Works Clearinghouse reports yielded findings lacking support for the effectiveness of Orton-Gillingham interventions. We conducted a meta-analysis to examine the effects of Orton-Gillingham reading interventions on the reading outcomes of students with or at risk for WLRD. Findings suggested Orton-Gillingham reading interventions do not statistically significantly improve foundational skill outcomes (i.e., phonological awareness, phonics, fluency, spelling; effect size [ES] = 0.22; p = .40), although the mean ES was positive in favor of Orton-Gillingham-based approaches. Similarly, there were not significant differences for vocabulary and comprehension outcomes (ES = 0.14; p = .59) for students with or at risk for WLRD. More high-quality, rigorous research with larger samples of students with WLRD is needed to fully understand the effects of Orton-Gillingham interventions on the reading outcomes for this population.

Problem Behaviors and Response to Reading Intervention for Upper Elementary Students With Reading Difficulties.

This study investigated the extent to which problem behaviors were factors associated with response to a year-long multicomponent reading intervention for fourth- and fifth-grade students with reading difficulties. Students scoring ≤85 standard score on the Test of Silent Reading Efficiency and Comprehension (n = 108), a reading fluency and comprehension screener measure, were randomized to the researcher-provided treatment condition (n = 55) or the business-as-usual comparison condition (n = 53). Results indicated that problem behaviors were associated with lower reading comprehension outcomes. Findings also suggested that students with higher levels of overall problem behaviors and externalizing behaviors in the treatment condition outperformed similar students in the comparison condition on the Gates-MacGinitie Reading Test (p < .05). Future research is needed on how to best identify, develop, and adapt effective interventions for students with reading difficulties and problem behaviors within school-wide response to intervention frameworks.

The Role of Knowledge Availability in Forming Inferences with Rural Middle Grade English Learners.

We investigated differences in knowledge-based inferencing between rural, middle grade monolingual English-speaking students and English learners. Students were introduced to facts about an imaginary planet Gan followed by a multi-episode story about Gan. Participants were tested on the accuracy of fact recall and inferences using this knowledge at three time points (i.e., immediate, one-week, and one-month follow-up). Results show that monolingual English-speaking students significantly outperformed English learners on the inference task. Both subgroups made elaborative inferences more accurately than coherence. Students' ability to recall knowledge base facts was the strongest predictor of their ability to accurately make inferences using this knowledge at each time point.

Current Research Informing the Conceptualization, Identification, and Treatment of Dyslexia Across Orthographies: An Introduction to the Special Series.

This introduction to the special series summarizes evidence for the genetic and brain bases for dyslexia and cognitive-behavioral indicators (including ones that can be measured even before the onset of reading instruction) that attest to meaningful differences between children with dyslexia and their non-dyslexic peers. Authors review controversies that have surrounded approaches to dyslexia identification and treatment during the last few decades. Finally, they introduce the findings of the articles in the special series and discuss potential implications for dyslexia identification and treatment.

Examining the Reading and Cognitive Profiles of Students With Significant Reading Comprehension Difficulties.

This study investigated the word reading and listening comprehension difficulties of fourth-grade students with significant reading comprehension deficits and the cognitive difficulties that underlie these weaknesses. Latent profile analysis was used to classify a sample of fourth-grade students (n = 446) who scored below the 16th percentile on a measure of reading comprehension into subgroups based on their performance in word reading (WR) and listening comprehension (LC). Three latent profiles emerged: (a) moderate deficits in both WR and LC of similar severity (91%), (b) severe deficit in WR paired with moderate LC deficit (5%), and (c) severe deficit in LC with moderate WR difficulties (4%). Analyses examining the associations between cognitive attributes and group membership indicated students with lower performance on cognitive predictors were more likely to be in a severe subgroup. Implications for educators targeting improved reading performance for upper elementary students with significant reading difficulties were discussed.

The Effects of a Paraphrasing and Text Structure Intervention on the Main Idea Generation and Reading Comprehension of Students with Reading Disabilities in Grades 4 and 5.

This study examined the effects of a small group intervention targeting paraphrasing and text structure instruction on the main idea generation and reading comprehension of students with reading disabilities in Grades 4 and 5. Students (N = 62) were randomly assigned to receive the Tier 2-type intervention or business-as-usual instruction. Students in the intervention received 25, 40-minute lessons focused on paraphrasing sections of text by identifying the main topic and the most important idea about that topic. Students utilized the text structure organization to inform their main idea generation. Results yielded statistically significant, positive effects in favor of the intervention group on near-transfer and mid-transfer measures of text structure identification (g = 0.75) and main idea generation (g = 0.70), but no statistically significant effect on a far-transfer measure of reading comprehension. These findings provide initial support for utilizing this instruction to improve students' main idea generation on taught and untaught structures.

Examining Sources and Mechanisms of Reading Comprehension Difficulties: Comparing English Learners and Non-English Learners within the Simple View of Reading.

In the present study, we compared the extent to which linguistic comprehension (vocabulary and listening comprehension) and word reading explain reading comprehension differentially for English learners (ELs) and non-ELs with reading difficulties, and we investigated whether different mechanisms of reading comprehension failure exist for each group. Using the simple view of reading as our framework, we tested a model in which vocabulary exerts a direct effect on reading comprehension and indirect effects through listening comprehension and word reading. Results from a multigroup structural equation model with a sample of 446 struggling fourth-grade readers (n = 229 for ELs; n = 211 for non-ELs) demonstrated both similarities and differences in the sources and mechanisms of reading comprehension difficulties for ELs and non-ELs with reading problems. Word reading was an important source of reading comprehension difficulty for both groups. For non-ELs, the effect of word reading was larger than the effects of linguistic comprehension (vocabulary and listening comprehension combined); however, for ELs, the effects of linguistic comprehension were greater than the effect of word reading. Vocabulary had indirect effects via both listening comprehension and word reading for ELs, but it demonstrated a direct effect on reading comprehension for non-ELs. These results suggest that developing a range of linguistic comprehension skills (e.g., word-level and sentence-level language skills) may be important for ELs with reading comprehension difficulties in the upper-elementary grades.

How Initial Word Reading and Language Skills Affect Reading Comprehension Outcomes for Students With Reading Difficulties.

This study examined how differences in listening comprehension and word reading at the beginning of the school year influence changes in reading comprehension for English learners (ELs) with significant reading difficulties compared to non-ELs with significant reading difficulties. The study investigated heterogeneity in response to instruction among 400 struggling readers in fourth grade (n = 183 for non-EL; n = 217 for EL) who received an intensive reading intervention. At pretest, word reading, listening comprehension, and reading comprehension were measured, and at posttest, reading comprehension was measured again. Results from moderated multiple regression analyses showed a significant three-way interaction such that reading comprehension at posttest was higher for ELs than non-ELs with similar levels of low word reading but relatively higher levels of listening comprehension. However, non-ELs outperformed ELs with similar levels of relatively high word reading and average to high listening comprehension. The findings suggest that pre-intervention skill profiles may need to be interpreted differently for ELs and non-ELs with significant reading difficulties in relation to language and literacy outcomes.

The Relationship Between Study Quality and the Effects of Supplemental Reading Interventions: A Meta-Analysis.

Empirical studies investigating supplemental reading interventions for students with or at-risk for reading disabilities in the early elementary grades have demonstrated a range of effect sizes. Identifying the findings from high quality research can provide greater certainty of findings related to the effectiveness of supplemental reading interventions. This meta-analysis investigated how four variables of study quality (study design, statistical treatment, Type I error, and fidelity of implementation) were related to effect sizes from standardized measures of foundational reading skills and language/comprehension. The results from 88 studies indicated that year of publication was a significant predictor of effect sizes for both standardized measures of foundational reading skills and language/comprehension, with more recent studies demonstrating smaller effect sizes. Results also demonstrated that with the exception of research design predicting effect sizes on foundational reading skills measures, study quality was not related to the effects of supplemental reading interventions. Implications for research and practice are discussed.

Reading Instruction for English Learners With Learning Disabilities: What Do We Already Know, and What Do We Still Need to Learn?

This paper reviews findings from four research syntheses that report the effects of academic language and/or reading interventions on language and reading outcomes for English learners who have or are at risk for learning difficulties. Studies included in the syntheses varied in research design and addressed multiple areas of reading and language. There was disagreement between syntheses as to the extent of research evidence in favor of particular instructional practices. For ELs with learning difficulties in kindergarten and first grade, however, there was strong consensus that multiple-component reading instruction that includes phonological awareness and phonics instruction is associated with improved word reading outcomes. It may also be beneficial to provide oral language, vocabulary, and reading comprehension instruction; nevertheless, there is a need for future research on instructional interventions that aim to improve reading comprehension outcomes for this population.

Cognitive, Intervention, and Neuroimaging Perspectives on Executive Function in Children With Reading Disabilities.

The role of executive function (EF) in the reading process, and in those with reading difficulties, remains unclear. As members of the Texas Center for Learning Disabilities, we review multiple perspectives regarding EF in reading and then summarize some of our recent studies of struggling and typical readers in grades 3-5. Study 1a found that a bi-factor structure best represented a comprehensive assessment of EF. Study 1b found that cognitive and behavioral measures of EF related independently to math and reading. Study 1c found that EF related to reading, above and beyond other variables, but Study 1d found no evidence that adding an EF training component improved intervention response. Study 1e found that pretest EF abilities did not relate to intervention response. Neuroimaging studies examined EF-related brain activity during both reading and nonlexical EF tasks. In Study 2a, the EF task evoked control activity, but generated no differences between struggling and typical readers. The reading task, however, had group differences in both EF and reading regions. In Study 2b, EF activity during reading at pretest was related to intervention response. Across studies, EF appears involved in the reading process. There is less evidence for general EF predicting or improving intervention outcomes.

Executive Functions and Response to Intervention: Identification of Students Struggling with Reading Comprehension.

Inadequate responders demonstrate significant risk for learning disabilities. Previous investigations of the cognitive profiles of inadequate and adequate responders have not included measures of executive functions (EF), which have well-documented associations to reading comprehension. We evaluated EF performance on a common factor comprised of shared variance across tasks as well as five separable EF factors in the context of an intensive reading intervention for struggling fourth graders. To determine if EF performance at pretest is associated with subsequent responder status, we compared EF performance of three subgroups of students: inadequate and adequate responders and typical students not at-risk for reading disabilities. Results of discriminant function analyses and linear regression models comparing groups were largely null; EF performance at pretest demonstrated only small associations with responder status. These results suggest that the assessment of EF may have limited value in predicting which individual students will respond to intensive reading interventions.
