Note. Significance statistic was calculated using ANCOVA with treatment group as a predictor and pretest scores, gender, and therapy as covariates. Cohen’s d was calculated by using raw scores of group difference means and pooled standard deviations. N of participants = 109, intervention = 55, control = 54.
