This study presents findings of longitudinal research that studied the predictive utility of five temperament constructs measured in preschool children and their subsequent behavioral adjustment 5 years later in elementary school. Adjustment as measured by composites of the Behavior Assessment System for children was predicted by parent ratings of children's temperament over a 5-year period. Consistent with previous research over a 3-year period by the same authors, emotional intensity was found to be the strongest predictor of all composites. Parentally perceived emotionality contributes to school perceived adjustment. These findings support the importance of early pro-social skill training of children to enhance adjustment. (Author/EMK)
