Changes in negative affect, rumination, self-compassion, and self-discrepancies, from pre- to post-intervention
depression
Bayesian repeated measures ANOVAs were conducted on negative affect, rumination, self-discrepancies, and self-compassion with time (pre-and post-intervention) as a within-subjects factor, group (LKM, colouring) as a between-subjects factor, and intervention compliance as a covariate. An analysis of residuals confirmed the assumptions of linearity. For negative affect (total DASS), results were inconclusive regarding a main effect of time, BF10 = 2.40, and group, BF10 = 0.45, and there was no interaction between time and group, BF10 = 0.32. Results suggested no difference in the reduction of negative affect over time depending upon group. The Bayesian repeated measures ANOVA for depression (DASS depression) revealed inconclusive results regarding a main effect of time, BF10 = 0.94, and group, BF10 = 0.72, and there was no interaction between time and group, BF10 = 0.28, suggesting no difference in the reduction of depression over time depending upon group. Regarding rumination (RRS), there was a main effect of time, BF10 = 9.15, but inconclusive results regarding a main effect of group, BF10 = 1.93, and regarding an interaction between time and group, BF10 = 0.85. Results suggested no reliable conclusion could be drawn regarding a difference in the reduction of rumination over time depending upon group. Further, the Bayesian repeated measures ANOVA for self-compassion revealed inconclusive results regarding a main effect of time, BF10 = 1.00, while there was no main effect of group, BF10 = 0.006. Further, results were inconclusive regarding an interaction between time and group, BF10 = 1.18, suggesting no reliable conclusion could be drawn regarding a change in self-compassion over time depending upon group. There was a main effect of time for experienced self-discrepancies (
