Does the Effectiveness of a Reading Intervention Differ Dependent on Students' Spanish or English Proficiencies?

This study investigated whether linguistic proficiencies in students' first language (L1)- Spanish-and English (L2) moderated the response to intensive reading intervention for sixth- and seventh-grade multilingual learners (MLs) with reading difficulties. We used confirmatory factor analysis to estimate proficiency scores in English and Spanish using measures of expressive and receptive vocabulary, syntax, and grammar. We then used latent variable moderated structural equation modeling to evaluate how proficiency in English and Spanish moderated the effect of treatment on students' reading outcomes in response to intervention.

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 ( = 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.

The critical role of instructional response in defining and identifying students with dyslexia: a case for updating existing definitions.

We address defining and identifying students with dyslexia within the context of multi-tier systems of support (MTSS). We review proposed definitions of dyslexia, evidence for proposed definitional attributes, and emphasize the role of instructional response in identifying students with dyslexia. We identify dyslexia as individuals with specific deficits in reading and spelling single words combined with inadequate response to evidence-based instruction.

Assessment of Specific Learning Disabilities and Intellectual Disabilities.

We review literature related to the assessment and identification of Specific Learning Disabilities (SLD) and Intellectual Disabilities (ID). SLD and ID are the only two disorders requiring psychometric test performance for identification within the group of neurodevelopmental disorders in . SLD and ID are considered exclusionary of one another, but the processes for assessment and identification of each disorder vary.

The reading profiles of late elementary English learners with and without risk for dyslexia.

Few studies have systematically investigated the reading skill profiles of English learners (ELs) in late elementary school, a critical developmental period for language and literacy and the most common grades for initial identification with specific learning disabilities (O'Connor et al., Learning Disabilities Research & Practice, 28(3), 98-112, 2013). We investigated the reading skill profiles of 331 ELs in 3rd and 4th grades, including ELs with and without risk for dyslexia due to significant deficits in word and pseudo-word reading accuracy and fluency.

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 ( = 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%).

Visual attention and reading: A test of their relation across paradigms.

Relations of visual attention to reading have long been hypothesized; however, findings in this literature are quite mixed. These relations have been investigated using several different visual attention paradigms and with variable controls for other competing reading-related processes. We extended current knowledge by evaluating four of the key visual attention paradigms used in this research-visual attention span, attention blink, visual search, and visuospatial attention-in a single study.

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 4 and 5 grade struggling readers (mean age = 10.3 years) on behavioral ratings of attention, sustained attention, and reading over a school year.

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 ( = 108), a reading fluency and comprehension screener measure, were randomized to the researcher-provided treatment condition ( = 55) or the business-as-usual comparison condition ( = 53). Results indicated that problem behaviors were associated with lower reading comprehension outcomes.

Structure Altering Effects of a Multicomponent Reading Intervention: An Application of the Direct and Inferential Mediation (DIME) Model of Reading Comprehension in Upper Elementary Grades.

We evaluate the direct and inferential mediation (DIME) model for reading comprehension with a sample of struggling readers in Grades 3 to 5 ( = 364) in the context of a large-scale randomized controlled trial (RCT) investigating two theoretically distinct reading interventions (text processing + foundational skills [ = 117] or text processing only [ = 120]) and a control condition ( = 127). We investigate whether the intervention affects not just reading comprehension levels, but also how variables within the reading system interrelate. This approach allows the focus to shift from intervention as influencing a change in reading comprehension status to a complex set of processes.

The Structure of Processing Speed in Children and its Impact on Reading.

The present study had two aims. First, we set out to evaluate the structure of processing speed in children by comparing five alternative models: two conceptual models (a unitary model, a complexity model) and three methodological models (a stimulus material model, an output response model, and a timing modality model). Second, we then used the resulting models to predict multiple types of reading, a highly important developmental outcome, using other well-known predictors as covariates.

The Role of Reading Anxiety among Struggling Readers in Fourth and Fifth Grade.

Cognitive predictors of reading are well known, but less is understood about the roles of "noncognitive" factors, including emotional variables such as anxiety. While anxiety has been a focus of study, its analogue in the reading literature is understudied. We assessed struggling fourth and fifth graders ( = 272) on reading anxiety in the context of general anxiety, cognitive predictors (working memory, verbal knowledge), and demographics.

The Critical Role of Instructional Response for Identifying Dyslexia and Other Learning Disabilities.

This article addresses the nature of dyslexia and best practices for identification and treatment within the context of multitier systems of support (MTSS). We initially review proposed definitions of dyslexia to identify key commonalities and differences in proposed attributes. We then review empirical evidence for proposed definitional attributes, focusing on key sources of controversy, including the role of IQ, instructional response, as well as issues of etiology and immutability.

Executive Function: Association with Multiple Reading Skills.

Executive function (EF) is related to reading. However, there is a lack of clarity around (a) the relative contribution of different components of EF to different reading components (word reading, fluency, comprehension), and (b) how EF operates in the context of known strong language predictors (e.g.

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 ( = 183 for non-EL; = 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.

Examining the Effects of Afterschool Reading Interventions for Upper Elementary Struggling Readers.

We examined the efficacy of an afterschool multicomponent reading intervention for third- through fifth-grade students with reading difficulties. A total of 419 students were identified for participation based on a 90 standard score or below on a screening measure of the Test of Silent Reading Efficiency and Comprehension. Participating students were randomly assigned to a business as usual comparison condition or one of two reading treatments.

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.

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.

Efficacy of a Word- and Text-Based Intervention for Students With Significant Reading Difficulties.

We examine the efficacy of an intervention to improve word reading and reading comprehension in fourth- and fifth-grade students with significant reading problems. Using a randomized control trial design, we compare the fourth- and fifth-grade reading outcomes of students with severe reading difficulties who were provided a researcher-developed treatment with reading outcomes of students in a business-as-usual (BAU) comparison condition. A total of 280 fourth- and fifth-grade students were randomly assigned within school in a 1:1 ratio to either the BAU comparison condition ( n = 139) or the treatment condition ( n = 141).

Adoption Costs Associated With Processing Strengths and Weaknesses Methods for Learning Disabilities Identification.

There is controversy regarding the relative merits of cognitive assessment for the identification of learning disabilities. Proponents of cognitive assessment have suggested that multitiered systems of support (MTSS) should be supplemented with routine, systematic assessment of cognitive processes following a determination of inadequate response to evidence-based interventions in order to document a pattern of processing strengths and weaknesses (PSW methods) as an inclusionary criterion for learning disabilities. However, the financial costs incurred by this addition to MTSS are not well known.

A framework for executive function in the late elementary years.

Objective: Executive function (EF) is a commonly used but difficult to operationalize construct. In this study, we considered EF and related components as they are commonly presented in the neuropsychological literature, as well as the literatures of developmental, educational, and cognitive psychology. These components have not previously been examined simultaneously, particularly with this level of comprehensiveness, and/or at this age range or with this sample size.

The Effects of One versus Two Years of Intensive Reading Intervention Implemented with Late Elementary Struggling Readers.

We examined the effectiveness of a researcher-provided reading intervention with 484 fourth graders with significant reading difficulties. Students were randomly assigned to one year of intervention, two years of intervention, or a business-as-usual comparison condition (BAU). Students assigned to two years of intervention demonstrated significantly greater gains in reading fluency compared to students who received one year of intervention and the BAU group.

Simulation of LD Identification Accuracy Using a Pattern of Processing Strengths and Weaknesses Method With Multiple Measures.

We investigated the classification accuracy of learning disability (LD) identification methods premised on the identification of an intraindividual pattern of processing strengths and weaknesses (PSW) method using multiple indicators for all latent constructs. Known LD status was derived from latent scores; values at the observed level identified LD status for individual cases according to the concordance/discordance method. Agreement with latent status was evaluated using (a) a single indicator, (b) two indicators as part of a test-retest "confirmation" model, and (c) a mean score.

Comprehensive Cognitive Assessments are not Necessary for the Identification and Treatment of Learning Disabilities.

There is considerable controversy about the necessity of cognitive assessment as part of an evaluation for learning and attention problems. The controversy should be adjudicated through an evaluation of empirical research. We review five sources of evidence commonly provided as support for cognitive assessment as part of the learning disability (LD) identification process, highlighting significant gaps in empirical research and where existing evidence is insufficient to establish the reliability and validity of cognitive assessments used in this way.

Do Processing Patterns of Strengths and Weaknesses Predict Differential Treatment Response?

Objective: No previous empirical study has investigated whether the LD identification decisions of proposed methods to operationalize processing strengths and weaknesses (PSW) approaches for LD identification are associated with differential treatment response. We investigated whether the identification decisions of the concordance/discordance model (C/DM; Hale & Fiorello, 2004) and Cross Battery Assessment approach (XBA method; Flanagan, Ortiz, & Alfonso, 2007) were consistent and whether they predicted intervention response beyond that accounted for by pretest performance on measures of reading.

Method: Psychoeducational assessments were administered at pretest to 203 4 graders with low reading comprehension and individual results were utilized to identify students who met LD criteria according to the C/DM and XBA methods and students who did not.
