Youth Self Report of Behavioral and Emotional Problems in a Swiss Epidemiological Study

The Youth Self Report (YSR) was used in a Swiss epidemiological study with 1093 subjects aged 10–17 years. Internal consistency was good for the second-order factors “Internalizing Problems,” “ExternalizingProblems,” and the “Total Problem Score,” whereas it was less satisfactory for almost all syndrome scales. In general, internal consistency coefficients were slightly lower in the Swiss sample than in the U.S. sample. Correlations between the syndrome scales resulted in good replications of the original findings as obtained in the U.S. normative sample. Effect analyses showed that sex is more important than age and nationality (indigenous vs. immigrant subjects). However, all effects were small. Correspondence between YSR and Child Behavior Checklist scores showed that agreement between adolescents' and parents' reports is relatively small.
