Note. N=244. Gender, time, and treatment condition were estimated simultaneously as predictors of positive parenting in one multivariate MLM. Intercepts were centered at two-weeks post-treatment. Predictors were centered or effects coded. Effect sizes were interpreted from Cohen’s d as small (0.2), medium (0.5) and large (0.8). M̂_diff =the main effect for gender between mothers and fathers.
