N = 197. B, regression coefficient; SE(B), standard error; β, standardized regression coefficient; 95% CI of B, 95% confidence interval of the regression coefficient; R², variance; adj. R², adjusted variance. IIP-C, German version of the Inventory of Interpersonal Problems—Circumplex. ^aDichotomous variable with values 0 = no previous psychotherapy, 1 = at least one previous psychotherapy. ^bAveraged sum score across subscales, ranging from 0 to 32, with higher scores indicating a higher degree of interpersonal difficulties. ^cSum score, ranging from 4 to 16, with higher scores indicating higher initiative as an indicator for higher motivation for psychotherapy.
