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…

Research designs involving cluster randomization are becoming increasingly important in educational and behavioral research. Many of these designs involve two levels of clustering or nesting (students within classes and classes within schools). Researchers would like to compute effect size indexes based on the standardized mean difference to…

The relation between self-concept and academic achievement was examined in 39 independent and longitudinal samples through the integration of meta-analysis and path analysis procedures. For relations with more than 3 independent samples, the mean observed correlations ranged from 0.20 to 0.27 between prior self-concept and subsequent academic…

The use of causal indicators to formatively measure latent constructs appears to be on the rise, despite what appears to be a troubling lack of consistency in their application. Scholars in any discipline are responsible not only for advancing theoretical knowledge in their domain of study but also for addressing methodological issues that…

This meta-analytic review was performed to determine the relationship between gender and two constructs measuring success in distance learning--academic performance and self-efficacy--with a particular interest in identifying whether females or males have an advantage in distance learning environments. Data from 15 studies resulted in 18 effect…

Purpose: To evaluate the effectiveness of behavioral interventions designed to treat stuttering in children. Method: Studies were included for review if (a) the treatment was a behavioral intervention, (b) participants were between 2 and 18 years old, (c) the design was an experimental or quasi-experimental group design, and (d) the reported…

Background/Context: Earlier research on various forms of distance learning concluded that these technologies do not differ significantly from regular classroom instruction in terms of learning outcomes. Now that web-based learning has emerged as a major trend in both K-12 and higher education, the relative efficacy of online and face-to-face…

Considerable attention has been paid across international contexts to structural factors affecting the sustainability of the early childhood workforce. While attention to these elements is vital, it can nevertheless overshadow less tangible elements that may contribute to, or assist in addressing, problems of workforce sustainability. In…
