Mediation analysis in Single Case Experimental Designs (SCEDs) evaluates intervention mechanisms for individuals. Despite recent methodological developments, no clear guidelines exist for maximizing power to detect the indirect effect in SCEDs. This study compares frequentist and Bayesian methods, determining (1) minimum required sample size to…

In educational research, the complexity of interventions and the diversity of contexts challenge the adequacy of existing reporting standards, primarily tailored for health interventions and randomised controlled trials. Recognising the critical need for appropriate tools to support education research, we developed two checklists: the CheckList Of…

This systematic literature review provides a comprehensive evaluation of the experimental intervention research being published from 2010 to 2020 within "Career Development and Transition for Exceptional Individuals" (CDTEI). We critically evaluated studies found through a hand-search of CDTEI and identified patterns and trends across…

Purpose: In the evolving landscape of the 21st century, characterized by dynamic global challenges such as health crises, climate change, and rapid technological advancements, the imperative of lifelong learning has become more pronounced than ever. Self-Regulated Learning (SRL) plays a pivotal role in lifelong learning, involving independent,…

Random encouragement designs evaluate treatments that aim to increase participation in a program or activity. These randomized controlled trials (RCTs) can also assess the mediated effects of participation itself on longer term outcomes using a complier average causal effect (CACE) estimation framework. This article considers power analysis…

Meta-analytic studies of second language (L2) learning typically employ a classic approach to meta-analysis. Although the classic approach can clarify findings, a multivariate, multilevel meta-analysis (3M) approach increases transparency by accounting for (a) dependencies in the evidence presented by primary studies, (b) methodological…

Objectives: To determine ADHD research priorities from the perspective of ADHD professionals internationally. Method: A two-stage modified Delphi design was used. In Stage 1 (qualitative), participants listed research questions relating to ADHD that they perceived to be most important (N = 132). In Stage 2 (quantitative), participants were then…
