Overview of sample attrition for the current study.
Data set 1 (adolescents) and 2 (parents) were used separately for descriptive and psychometrical analyses. Dataset 3 consisted of matched adolescent-parent-dyads for the agreement analyses.

Comparison of relative frequencies of responses for the adolescents per subscale.
Due to rounding, not all percentages sum up to 100%. aSample size N = 117. b Values from the original English study [31] summed on the subscale level. Sample size N = 227.

Comparison (in %) of absolute subscale and total scale values between self-report (PCSI-S13) and parent-report (PCSI-P).
Number of observations = 103. “Self-report > Parent-report” = proportion of higher scale scores for adolescents compared to parents, “Self-report = Parent-report” = proportion of equal scale scores between parents and adolescents, “Parent-report > Self-report” = proportion of higher scale scores for parents compared to adolescents. a Cognition subscale: Adolescents’ subscale score without item 18.
