Positive Behavior Support (PBS) for behavioral problems was included in the 1997 Individuals With Disabilities Education Act reauthorization, reflecting the increased implementation and strengthening empirical evidence for PBS in schools. Whereas PBS can be used reactively, its flexibility has led to a popular comprehensive school-wide model used…

Recent meta-analytic efforts have documented how couple and relationship education (CRE) programs promote healthy relationship and family functioning. The current meta-analysis contributes to this body of literature by examining stepfamily couples, an at-risk, subpopulation of participants, and assessing the effectiveness of CRE programs for…

This meta-analysis summarizes empirical results on the correspondence between teachers' judgments of students' academic achievement and students' actual academic achievement. The article further investigates theoretically and methodologically relevant moderators of the correlation between the two measures. Overall, 75 studies reporting…

The association between object play and intentional communication was examined in children with autism spectrum disorder (ASD). Meta-analysis of concurrent and longitudinal correlational studies revealed significant associations between object play and intentional communication in young children with ASD. One well-conducted and internally valid,…

What changes have taken place in the equalization of opportunities for entering higher education in China since the 1990s? The results of empirical analyses of nationwide urban and rural data conducted in the first part of this article indicate that, if the internal stratification within institutions of higher education is not considered,…

Many differences in brain activity have been reported between persons who stutter (PWS) and typically fluent controls during oral reading tasks. An earlier meta-analysis of imaging studies identified stutter-related regions, but recent studies report less agreement with those regions. A PET study on adult dextral PWS (n = 18) and matched fluent…

Remembering the past and envisioning the future are at the core of one's sense of identity. Neuroimaging studies investigating the neural substrates underlying past and future episodic events have been growing in number. However, the experimental paradigms used to select and elicit episodic events vary greatly, leading to disparate results,…

Objective: Behavioral inhibition (BI) has been associated with increased risk for developing social anxiety disorder (SAD); however, the degree of risk associated with BI has yet to be systematically examined and quantified. The goal of the present study was to quantify the association between childhood BI and risk for developing SAD. Method: A…

Objective: Gender differences among children with ADHD are not well understood. The continuous performance test (CPT) is the most frequently used direct measure of inattention and impulsivity. This meta-analysis compared CPT performance between boys and girls with and without ADHD. Method: All peer-reviewed ADHD studies published between 1980 and…

Identity formation is an essential developmental challenge associated with adolescence ([17], [20] and [21]). Berzonsky (1988) developed a social-cognitive model that distinguishes three styles by which adolescents engage the tasks associated with identity formation: informational, normative, and diffuse-avoidant. Focusing on studies (K = 62) that…

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…

This article presents some results arising from the meta-analysis of the educational research that has been developed at Universidade Nova de Lisboa (Portugal). The intention was to understand the status of the educational research produced, the main thematic trends studied, affiliated scientific domains, conceptual frames mobilized, and…

Objective: The role of diet and of food colors in attention-deficit/hyperactivity disorder (ADHD) or its symptoms warrants updated quantitative meta-analysis, in light of recent divergent policy in Europe and the United States. Method: Studies were identified through a literature search using the PubMed, Cochrane Library, and PsycNET databases…

The "No Child Left Behind" Act of 2001 requires the US educational systems to provide effective instruction for all students to be successful in reading. It is generally accepted that there are five essential components for effective reading instruction: phonological awareness, alphabetic understanding, vocabulary, fluency, and reading…

This meta-analysis examined the extent to which stereotypes of leaders are culturally masculine. The primary studies fit into 1 of 3 paradigms: (a) In Schein's (1973) "think manager-think male paradigm", 40 studies with 51 effect sizes compared the similarity of male and leader stereotypes and the similarity of female and leader…
