Note. ***p < 0.001; effect size is considered small for ηp2 > 0.01, medium for ηp2 > 0.06 and large for ηp2 > 0.14, only effect sizes ηp² > 0.14 are included; sui+ = patients with suicidal ideation at T1, sui- = patients without suicidal ideation at T1; M=mean score; SD = standard deviation; a = significantly higher scores for sui+ than sui- at baseline T1. b = significantly higher scores for sui- than sui+ at baseline T1; between-subject-scores sui+: F(17, 110) = 16.542, p < 0.001, ηp² = 0.719; between-subject-scores sui-: F(17, 550) = 31.734, p < 0.001, ηp² = 0.495; for a detailed overview, see Supplementary Material Table S1.
