a trend toward significancep = .075
Receiving additional psychotherapy showed a trend toward significance ( p = .075) such that the participants who received additional psychotherapy had a higher BDI-II sum score at t1. 3.3 Research question 2 A repeated-measures ANOVA with a Greenhouse-Geisser correction demonstrated that for both groups, the mean performance levels differed significantly between measurements; intervention group: F (2.29, 107.35) = 11.89, p < .001, partial η 2 = .20, and waitlist group: F (2.58, 123.69) = 13.78, p < .001, partial η 2 = .22.
