Behavioral symptomatology was evaluated at the end of each week by counselors’ completion of the TRF (Achenbach, 1991a). The TRF is a widely used and validated instrument to assess behavioral disturbance from the perspective of teachers, and the measure was used in the present study, because camp counselors are able to observe similar behaviors to that of teachers. The TRF, containing 118 items rated for frequency, assesses two broadband dimensions of child symptomatology, externalizing and internalizing, as well as total behavior problems. Subscales scores are also computed for the following factors: withdrawn, somatic problems, anxiety/depression, social problems, thought problems, attention problems, delinquent behavior, and aggressive behavior. In the present study, interrater reliability for the internalizing and externalizing scales based on average intraclass correlations among pairs of raters. Across the years, reliabilities ranged from .56 to .84 (M = .68) for internalizing and from .78 to .88 (M = .83) for externalizing. The counselors’ scores for each child were averaged to obtain individual child scores for the broadband dimensions.
