Parents completed the Child Behavior Checklist (CBCL; Achenbach and Rescorla 2001) about their child. The CBCL includes a 118-item checklist of problem behaviors during the previous 6 months. Youths completed the Youth Self Report (YSR; Achenbach and Rescorla 2001), the self-report version of the CBCL for adolescents 11–18 years of age. Children who were 9 or 10 years of age completed the YSR to allow for complete data on all measures. The CBCL and YSR assess a number of problem areas in youth, including anxiety, depression, oppositional behaviors, and attention, and reliability and validity of the CBCL and YSR are well established.
