Background: Within the same school class, it is usual to find children who differ in age by almost a full calendar year. Although associations between being relatively young and poor academic outcomes are well documented, and relatively consistent, the associations between being relatively young and psychosocial outcomes are less clearly…

Failure to exercise self-control is one of the leading causes of substance and behavioral addictions. Problematic social media usage (PSMU), a type of behavioral addiction, has become an increasingly serious problem with a significant impact on the lives of individuals of all generations. Therefore, it is crucial to understand the underlying…

Background: To document whether the sociocognitive peculiarities of people with Down Syndrome impact the construction of attachment at different ages, a systematic review of the literature was carried out. Method: This review followed the Preferred Reporting Items for Systematic Reviews and MetaAnalyses, was conducted on three databases: psycINFO,…

Reading proficiency is important because it has life-long consequences and influences success in other academic areas. Many students with behavior problems are poor readers and many students with learning disabilities have more behavior problems than their typical peers. We conducted a correlational meta-analysis to examine the association between…

To date, little is known about sensory processing in Williams syndrome (WS) and the similarities of the sensory profile in individuals with WS compared to people with other neurodevelopmental disorders. The current review aims to consolidate available evidence on sensory processing in WS. Eighteen primary studies investigating sensory processing…

Healthy relationships between parents and teachers are essential to addressing children's emotional and behavioral concerns. The current meta-analysis examined the effects of family-school engagement interventions on parent-teacher relationships. Twenty-three group-design studies yielding 58 effects comprised the current sample. Random effect…

Autism is associated with significantly higher rates of internalizing and externalizing disorders compared to neurotypical (NT) individuals. Emotion dysregulation (ED) is prevalent in autistic individuals and has been proposed to underlie both internalizing disorders and behavioral challenges in autism. This study sought to use a meta-analytic…

We conducted a meta-analytic review of 53 studies published between 2000 and 2020 to quantify associations of parents' emotion regulation with parenting behavior and children's emotion regulation and internalizing and externalizing symptoms. Twelve meta-analyses, which included between 4 to 22 effect sizes (N from 345 to 3609), were conducted to…

Externalizing behavior and low academic performance present key developmental challenges for school-age children, with the potential for these domains to predict each other over time, leading to worsened outcomes. Yet, previous studies have yielded inconsistent conclusions about the directional pathways between externalizing behaviors and academic…

Feeding difficulties related to selective intake, or eating a limited variety of foods, are very common in children with autism spectrum disorder (ASD). A systematic search of PubMed, Embase, PsycInfo, and CINAHL identified 29 studies that evaluated eight correlates: age, ASD symptoms and severity, cognitive and adaptive skills, sensory processing…

Paraprofessionals report spending a substantial amount of time addressing challenging behavior in a range of school environments, yet identify behavioral intervention as a high-priority training area. The purpose of this meta-analysis was to systematically review and summarize single-case intervention studies involving paraprofessional-delivered…

A growing body of evidence points to the common co-occurrence of language and behavioral difficulties in children. Primary studies often focus on this relation in children with identified deficits. However, it is unknown whether this relation holds across other children at risk or representative samples of children or over time. The purpose of…

Although many researchers have examined the prevalence of stereotypy in individuals with developmental disabilities, the results of previous studies have not been aggregated and analyzed methodically. Thus, we conducted a systematic review of studies reporting the prevalence of stereotypy in individuals with developmental disabilities. Our results…

The mental health impact of the coronavirus disease 2019 (COVID-19) pandemic on PK-12 youth is likely an urgent and enduring concern, yet research on this topic is still emerging. To synthesize current knowledge, the researchers conducted a systematic review of empirical studies exploring the mental health impacts of COVID-19. Five themes emerged…

The current meta-analysis examines the previous research on the utility of the Social Communication Questionnaire as a screening instrument for autism spectrum disorder. Previously published reports have highlighted the inconsistencies between Social Communication Questionnaire-screening results and formal autism spectrum disorder diagnoses. The…
