  1. The 1 week pre-treatment assessment consists of T0 data of the immediate intervention group and T0.1 data of the waiting list control condition. T1 1 week post-treatment assessment, FU1 12 weeks post-treatment assessment, FU2 24 weeks post-treatment assessment, PCBD persistent complex bereavement disorder, MDD major depressive disorder, PTSD posttraumatic stress disorder. Column 3 to 11 represent individual scores, and in case the score at T1, FU1, and FU2 significantly (p < .05) reliable differed from the pre-treatment score, based on the reliable change index, it was marked with “*”
