The Child Behavior Checklist, Teacher Report Form and Youth Self Report problem scales in a normative sample of Croatian children and adolescents aged 7-18.

ABSTRACT

The main goal of this study was to standardize the Child Behavior Checklist (CBCL), Teacher Report Form (TRF) and Youth Self Report (YSR) questionnaire problem scales on a normative random sample of children and adolescents (N=3309) aged 7 to 18 throughout Croatia. The second goal was to compare boys-girls problem scales data and CBCL-TRF-YSR differences in our sample. The mean value of CBCL scores for the Total Problems scale for different groups (children/adolescents; boys/girls) ranged from 17.07 to 20.71. Overall instruments' internal consistency ranged from 0.83 to 0.86. In almost all the scales parents reported higher scores than teachers (p < 0.01). In all the scales adolescents reported significantly higher scores than their parents and teachers (p < 0.01). This study standardized the questionnaires for our specific socio-cultural circle, which satisfy complex psychopathology study criteria. Problem scales results in our sample suggest similarity to previous European researches.
