Note: BDI = Beck Depression Inventory. Cases were assigned to groups using Bayes’s theorem with parameter estimates from MAXEIG analyses; taxon n = 361; complement n = 1,139. There were 583 men and 917 women. Cohen’s d was calculated standardized using pooled within-groups variances (weighted by df), and statistical significance is based on F values for main effects tested in a factorial ANOVA. There were no statistically significant Group × Gender interaction effects.
