In the measurement model, at Time 1 (T1) and Time 2 (T2), externalizing problems were composed of scores for counselor-rated externalizing symptoms from the TRF and aggressive behavior from the PEI, as well as peer nominations for aggressive and disruptive social behavior. Similarly, indicators for internalizing problems in both waves during childhood included counselor-rated internalizing symptoms from the TRF and nominations for withdrawn behavior from the PEI. The social competence indicators included peer nominations of leadership and cooperativeness, as well as scores for peer acceptance. During the two waves of assessment during adolescence, manifest variables for the externalizing latent variables included YSR scores for the delinquency and the aggression subscales; similarly, indicators for the internalizing latent variables were YSR scores for the subscales of withdrawn, anxious/depressed, and somatic problems.
