This study examined longitudinal associations between adolescents' and their friend's depressive symptoms and depressogenic attributional style. Participants included 398 adolescents in grades six through eight at the outset of the study. Adolescents completed peer nominations to identify reciprocated and unreciprocated best friendships as well as measures of depressive symptoms and depressogenic attributional style at an initial time point, and again 11 months later. Results revealed that best friends' reported level of depressive symptoms was prospectively associated with adolescents' own depressive symptoms and with adolescents' depressogenic attributional style. Moderator effects suggested that friends' attributional styles were prospectively associated with adolescents' own attributional styles for those involved in reciprocated friendships. Lastly, findings offered preliminary support for adolescents' Time 2 depressive symptoms as a mediator of the association between friends' depressive symptoms and adolescents' attributional style. Findings have important implications for cognitive and interpersonal models of adolescent depression, as well as the study of peer contagion effects.
Many students at risk for or identified with reading disabilities need intensive reading interventions. This meta-analysis provides an update to the Wanzek and Vaughn synthesis on intensive early reading interventions. Effects from 25 reading intervention studies are analyzed to examine the overall effect of intensive early reading interventions as well as relationships between intervention and student characteristics related to outcomes. The weighted mean effect size (ES) estimate (ES = 0.39), with a mean effect size adjusted for publication bias (ES = 0.28), both significantly different from zero, suggested intensive early reading interventions resulted in positive outcomes for early struggling readers in kindergarten through third grades. There was no statistically significant or meaningful heterogeneity in the study-wise effect sizes. Exploratory examination of time in intervention, instructional group size, initial reading achievement, and date of publication are provided.
Fluent word reading is hypothesized to facilitate reading comprehension by improving automatic word reading, thus releasing a reader’s cognitive resources to focus on meaning. Many students with learning disabilities (LD) struggle to develop reading fluency, which affects reading comprehension. This synthesis extends Chard, Vaughn, and Tyler’s (2002) review, synthesizing fluency intervention research from 2001 to 2014. The search yielded 19 studies examining reading fluency and comprehension outcomes of reading fluency interventions for students with LD in kindergarten through 5th grade. Results showed repeated reading (RR), multicomponent interventions, and assisted reading with audiobooks produced gains in reading fluency and comprehension. Providing a model of fluent reading and performance feedback, using easier level text, setting a performance criterion, and practicing RR with peers also contributed to improved outcomes. Findings suggest that RR remains the most effective intervention for improving reading fluency for students with LD. Limitations include sample size, only three group design studies, and infrequent use of standardized measures.
The purpose of this review was to conduct a meta-analysis of 25 years of mathematics interventions for students with mathematics difficulty or disability in Grades 4 through 12. A search of the literature yielded 25 studies that met the inclusion criteria. Studies were coded to extract important study information (e.g., participant information, research design, description of treatment, and comparison groups) and data needed to calculate Hedge’s g. We used robust variance estimation (RVE) to address dependence resulting from multiple outcomes per study. The RVE random-effects model estimated a treatment effect of 0.85. After adjusting for small-study effects, the final model estimated an underlying, moderate effect of 0.49 with a large amount of unexplained heterogeneity between studies. Studies with more than 15 hr of treatment and those focused on fraction content significantly moderated mathematics outcomes. Findings are limited by extreme variability across study estimates, the lack of standardized mathematics measures, and a limited number of studies across 25 years of research.
This systematic review examines the effects of summarizing and main idea interventions on the reading comprehension outcomes of struggling readers in Grades 3 through 12. A comprehensive search identified 30 studies published in peer-reviewed journals between 1978 and 2016. Studies included struggling reader participants in Grades 3 through 12; targeted summarizing or main idea instruction; used an experimental, quasi-experimental, or single-case design; and included a reading comprehension outcome. A meta-analysis of 23 group design studies resulted in a statistically significant mean effect of 0.97. Group size, number of sessions, grade level, and publication year did not moderate treatment effect. Visual analysis of six single-case designs yielded strong evidence for retell measures and a range of evidence for short-answer comprehension measures. Findings suggest that main idea and summarizing instruction may improve struggling readers’ main idea identification and reading comprehension. Limitations include the lack of standardized measures and the unreported, changing description of the counterfactual.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
