The Youth Self Report (YSR) of the Achenbach System of Empirically Based Assessment (Achenbach & Rescorla, 2001) (ASEBA) was completed by participants using a self administered version of the questionnaire and processed using the ASEBA’s Assessment Data Manager (Achenbach, 2002). Externalizing tendencies were defined by reports of rule-breaking and aggressive behavior. Internalizing tendencies were defined by endorsements of problems related to anxiety/depression, withdrawal/depression, and somatic complaints. The YSR has been found to correlate with diagnoses made by trained interviewers using the Diagnostic Interview Schedule for Children (Morgan & Cauce, 1999) and with ratings made by parents (Achenbach, Dumenci, & Rescorla, 2003).
