behaviour may vary from one context to another, or from one interaction partner to another, and informants» reports may be affected by their own perspectives.13 Because there is no gold standard for psychiatric disorders, and reports from different informants tend to correlate only moderately, using information from multiple informants seems the best strategy to

System of Empirically Based Assessment (ASEBA), 15,16 and the use of a teacher - report (Teacher Checklist of Psychopathology), which was developed for TRAILS on the basis of the Achenbach Teachers Report Form.17 It is also expressed in the use of peer nominations to assess adolescents» social status at school.
