Meta-analyses and structured reviews provide a synthesis of the results of multiple studies, thus offering unique contributions to informing practice and advancing science in the field of school psychology. High-quality meta-analyses and structured reviews include a review and summary of the extant studies and highlight clear directions for future…

We investigated characteristics of school-based mental health screening using multiple-gating (MG) approaches through a systematic review of the literature and proportional meta-analyses of screening participation and risk identification. The main analyses included 38 studies conducted in the United States. Pooled estimates indicate that…

Research has demonstrated that regular school attendance is necessary for acceptable academic performance and the development of desirable social skills and behaviors. One in seven students in the United States struggles with chronic absenteeism, and 36 states use accountability metrics that are designed to assess attendance rates as part of…

Research indicates that intensification in multitiered systems of support (MTSS) can prevent problem behavior and academic deficits from worsening and ensure that students with the most intensive needs receive the most appropriate supports. In MTSS, it is important to consider evidence-based practices that teachers can intensify to improve student…

Intelligence tests and adaptive behavior scales measure vital aspects of human functioning. Assessment of each is a required component in the diagnosis or identification of intellectual disability. The present study investigated the population correlation between intelligence and adaptive behavior using psychometric meta-analysis. The main…

One potential source contributing to the misdiagnosis and inappropriate treatment of attention deficit hyperactivity disorder (ADHD) could be as simple as a child's age in relation to others in their grade. Studies indicate that children who are youngest in their grade are at greater risk of being diagnosed with, and medicated for, ADHD. The…

Although the association between school suspension and deleterious outcomes is widely acknowledged, policy and practice need to be informed by an evidence base derived from multiple studies revealing consistent trends. This meta-analysis aims to address this void by examining the degree to which different types of school suspensions (in-school…

The present study took a meta-analytic approach to investigate whether students' engagement acts as a mediator in the association between affective teacher-student relationships and students' achievement. Furthermore, we examined whether results differed for primary and secondary school and whether similar results were found in a longitudinal…

This meta-analysis synthesized results about the association between empathy and defending in bullying. A total of 20 studies were included, with 22 effect sizes from 6 studies that separated findings by the defender's gender, and 31 effect sizes from 18 studies that provided effects for the total sample were included in the analysis. The weighted…

Off-task and disruptive classroom behavior impedes the learning of the children emitting these behaviors as well as the delivery of instruction to the entire class, which may lead to decreased academic achievement and more severe behavior problems. A meta-analysis of the single-case literature was conducted to understand the effectiveness of…

Recent meta-analyses of the effectiveness of token economies (TEs) report insufficient quality in the research or mixed effects in the results. This study examines the contemporary (post-Public Law 94-142) peer-reviewed published single-case research evaluating the effectiveness of TEs. The results are stratified across quality of demonstrated…

The current study meta-analyzed 47 single-subject studies of behavioral self-management interventions that were published between 1971 and 2011. In addition to obtaining an overall measure of effect across all self-management studies (f = 0.93), analyses were conducted to assess whether treatment effectiveness was moderated by factors such as…

Peer tutoring is an instructional strategy that involves students helping each other learn content through repetition of key concepts. This meta-analysis examined effects of peer tutoring across 26 single-case research experiments for 938 students in Grades 1-12. The TauU effect size for 195 phase contrasts was 0.75 with a confidence interval of…

This meta-analysis examined the direct (primary) and collateral (secondary) effects of peer tutoring on social and behavioral outcomes for 128 participants in prekindergarten through grade 12 across 20 studies using SCR designs. The overall TauU weighted effect size across studies was 0.62 (95% CI [0.58, 0.66]), indicating that a small to moderate…

Performance feedback (PF) has become popular in the school-based literature as a method to increase the treatment integrity of prescribed interventions. The current study extracted and aggregated data from single-case studies that used PF in school settings to increase teachers' use of classroom-based interventions. Results suggest PF is…
