This exploratory study builds upon extant reading development studies by identifying discrete groups based on reading comprehension trajectories across first grade. The main goal of this study was to enhance the field's understanding of early reading comprehension development and its underlying subcomponent skills, with the intent of better understanding the development of comprehension in students who display risk for reading difficulties and disabilities. A sample of first-grade readers (N = 314) were assessed at three timepoints across the first-grade year. These data were utilized to derive empirical latent classes based on reading comprehension performance across the first-grade year. Reading subcomponent skill assessments (phonological awareness, word reading, decoding, linguistic comprehension, and reading fluency), measured in the fall of first grade, were compared across latent classes to examine how they related to growth across the first-grade year. Results suggest that there were four distinct latent classes with differential reading comprehension development, each of which could also be distinguished by the subskill assessments. These findings are presented within the context of the broader reading research base, and implications for practice are discussed. [ABSTRACT FROM AUTHOR]

Difficulties with reading development have been well documented in samples of children with autism spectrum disorders. This study utilized a state-level early literacy dataset of kindergarten students educationally diagnosed with autism spectrum disorder (N = 616) to investigate the development of critical early reading skills across the kindergarten year. The study employed latent profile analysis and latent transition analysis to empirically derive profiles of early readers at kindergarten entry and the end of kindergarten. Results demonstrate the heterogenous nature of early reading skills for young school-aged students with autism spectrum disorder. Results have important implications for the early instruction and intervention of early reading for young children with autism spectrum disorder. Many children and young students with autism have difficulties learning how to read. This study investigated early literacy development in children with autism spectrum disorder during their first year of formal schooling. The study found that children with autism spectrum disorder differ greatly on their early literacy skills, with some showing strengths in their understanding of the alphabet, spelling, and reading words. Other students in the sample had difficulties with these early reading skills. The findings of this study are important to better understand the most effective way to teach early literacy skills to children with autism spectrum disorder. [ABSTRACT FROM AUTHOR]

Background and aims: Extant research indicates that children and adolescents with autism spectrum disorder (ASD) without an intellectual disability (ID) often experience difficulty comprehending written texts that is unexpected in comparison with their cognitive abilities. This study investigated the development of two key skills, narrative and inference abilities, that support higher level text comprehension and their relation to lexical-semantic knowledge, ASD symptomatology, and age. Three questions were addressed: 1.) What was the nature of narrative and inference skill development over time? 2.) What was the relation between narrative or inference development and lexical-semantic knowledge, ASD symptomatology, and age? 3.) Did initial narrative and inferencing skills, and the development of these skills, predict reading comprehension outcomes? Methods: Data from 81 children and adolescents with ASD without ID (FIQ ≥ 75) between the ages of 8-16-years-old at timepoint 1 were collected at 15-month intervals across three timepoints. ASD symptomatology was assessed with the ADOS-2. Standardized narrative retelling, inference, reading comprehension, lexical-semantic knowledge and cognitive assessments were administered. Latent growth curve models were conducted to examine narrative and inference skill development, and conditional growth models were fit to examine the relation between growth trajectories and covariates (lexical-semantic knowledge, ASD symptomatology, age) as well as with the reading comprehension distal outcome. Results: Narrative retelling skills followed a linear trajectory of growth and were a relative strength in this sample, while inference skills were well below average and declined over time relative to age-normed standard scores. Lexical-semantic knowledge explained significant heterogeneity in initial narrative and inference skills, whereas ASD symptomatology was only related to initial narrative retelling abilities and age was only related to initial inference abilities. Timepoint 3 reading comprehension skill (in the below average range) was significantly explained by initial narrative retelling and inference abilities. Conclusions: The results of this study indicate that narrative retelling and inference skills are important for successful reading comprehension for individuals with ASD without ID and that lexical-semantic knowledge underpins these skills. Furthermore, the observation that ASD symptom severity was associated with narrative retelling skills is consistent with the hypothesis that problems in narrative reading skills are associated with the autism phenotype. Finally, inference skill was a particular challenge for individuals in this sample, although age was positively associated with better performance on the assessment. Implications: These findings suggest that narrative and inference skills, in addition to lexical-semantic knowledge, are important to target beginning in elementary grades to improve reading comprehension outcomes for children and adolescents with ASD without ID.

The reading difficulties of individuals with autism spectrum disorders have been established in the literature, with particular attention drawn toward reading comprehension difficulties. Recent papers have highlighted the heterogeneous nature of reading abilities in this population by utilizing statistical methods that allow for investigations of unique reading profiles. This article extends this literature by investigating reading profiles longitudinally, to investigate the stability of reader profiles across time. Latent profile and transition analyses were conducted to establish categorically distinct reading profiles at two time points, 30 months apart. This study also examined whether age and autism symptom severity were related to the profiles at each time point. Finally, transitions between profiles at each time point were identified. Age did not predict profile membership, but there were significant differences in symptom severity that were largely stable over time. Results indicate that heterogeneous reading profiles exist within the autism population, ranging from average reading ability to severe difficulties across different reading subskills. The data from this study demonstrate that reading profiles of children and adolescents with autism spectrum disorders shift when examined across time. [ABSTRACT FROM AUTHOR]
