Notes: DPI, Developmental Profile Inventory; TCI, Temperament and Character Inventory; † F obtained by ANOVA; due to missing values, the degrees of freedom for the residuals of the model vary between 136[thus, F(2, 136)] and 137[thus, F(2,137)]; * = p ≤ .05; ** = p ≤ .01; *** = p ≤ .001. ‡ Cohen’s (1992): eta-squared: 0.02 = small; 0.13 = medium; 0.26 = large. § Post hoc test p-values reported only for significant F-tests. Where Post hoc tests were non-significant ns was reported. Analyses excluding deteriorated patients (n = 3) show equal results in terms of significance. As there were no significant between-group pretreatment differences in age, educational level, BMI or therapy type (group, individual) analyses were not adjusted for any of these potential covariates
