Using meta-analytic tests based on 87 statistically independent samples, we investigated the relationships between the five-factor model (FFM) of personality traits and organizational citizenship behaviors in both the aggregate and specific forms, including individual-directed, organization-directed, and change-oriented citizenship. We found that…

Research indicates that increasing teacher-directed opportunities to respond (TD-OTR) positively impacts student outcomes. Prior reviews of the empirical literature focused on outcomes for students with emotional behavioral disorders or on TD-OTRs as one of many classroom-management practices; however, prior reviews did not examine effects of…

Clinical and educational experience is one of the most commonly studied variables in clinical judgment research. Contrary to clinicians' perceptions, clinical judgment researchers have generally concluded that accuracy does not improve with increased education, training, or clinical experience. In this meta-analysis, the authors synthesized…

Research on the validity of psychosocial factors (PSFs) and other noncognitive predictors of college outcomes has largely ignored the practical benefits implied by the validity. We summarize evidence of the validity of PSF measures as predictors of college outcomes and then explain how this validity directly translates into improved identification…

The Non-Cognitive Questionnaire (NCQ) is a 23-item measure assessing eight noncognitive variables that are thought to predict the performance and retention of students in college. The NCQ is widely used in research and practice. This study is a meta-analytic review of the validity of scores on the NCQ across 47 independent samples for predicting…

Validity generalization meta-analysis (VG) examines the extent to which the validity of an instrument can be transported across settings. VG offers correction and summarization procedures designed in part to remove the effects of statistical artifacts on estimates of association between criterion and predictor. By employing a random effects model,…
