[The value of different sources of information in evaluating psychiatric disorders in adolescence--a comparison of parental judgment and self-assessment by adolescents].
Data from the national representative epidemiologic survey (PAK-KID-study) assessed by the German versions of Achenbach'S Child Behavior Checklist and Youth Self-Report of N = 1757 parents and their children aged 11 to 18 years are compared by using the corresponding Cross-Informant-Scales. On all problem scales adolescents report more problems than parents. For some scales the differences between girls and their parents are higher than between boys and their parents (social withdrawal, somatic complaints, anxious/depressed, attention problems, internalizing and total score). Averaged Pearson correlations of the eight subscales are in a moderate rage (r < 0.50). For all problem scales an agreement of 30% in the area of high problems (> PR95) is found. If one informant scores above PR95 the Relative Risk of the other one scoring in this range too is significantly higher than one for nearly all scales.
