“…Uttal et al (2013) implemented RVE in a meta-analysis that included 1,038 effect sizes from 206 studies that assessed the effect of training programs on spatial skills. Outside of educational research, RVE has been implemented in meta-analyses on the effectiveness of outpatient substance abuse treatment for adolescents (Tanner-Smith, Wilson, & Lipsey, 2013), the relationship between social goals and aggressive behavior in youth (Samson, Ojanen, & Hollo, 2012), and the effect of mindfulness-based stress reduction on physical and mental health in adults (de Vibe, Bjørndal, Tipton, Hammerstrøm, & Kowalski, 2012). No published examples of the use of three-level meta-analysis to handle dependence were found in the educational research literature.…”
