Note: Significance is defined as the original author’s determination of statistical significance. A criterion of p < .05 was used across all studies unless specifically noted otherwise. A + denotes a significant positive association, an = denotes no significant relationship and a +/= denotes that significant effects were found in one subset of a population but not another. An * denotes studies using multivariate analyses that accounted for other common predictors of completion such as age, gender and qualifying diagnoses.
