"Meta-Analysis of Random Assignment Studies of Interventions Targeting the Identified Competencies"
Author: Sabrina Solanki
The current meta-analysis investigated the extent to which motivational interventions improve academic performance for college students. We identified 32 published studies that used random assignment, manipulated an intrapersonal competency as identified by the National Research Council, and measured an academic performance outcome. Overall, interventions were significantly effective with an average effect size of g = 0.42 (95% confidence interval = [0.30 to .54]). Effects sizes varied in terms of competency, outcome, and target population (URM versus non-URM) but were uniformly positive. Preliminary regression results suggest that the differences in effect sizes were only significant for target population, but not for other moderators such as interpersonal competency.
