Linking childhood personality with adaptation: evidence for continuity and change across time into late adolescence.

Four personality traits--Mastery Motivation, Academic Conscientiousness, Surgent Engagement, and Agreeableness--were measured in a community sample of 205 children (ages 8-12), who were followed up 10 years later. Childhood personality was examined in relation to concurrent and longitudinal adaptation in 3 domains--academic achievement, rule-abiding versus antisocial conduct, and peer social competence. The childhood personality traits evidenced robust, conceptually coherent relationships with adaptation, both concurrently and across time. Childhood personality added to the prediction of later adaptation, beyond childhood IQ and earlier adaptation in the same domain. Few sex differences were obtained in the relationships between childhood personality and adaptation. The present results document both continuity and discontinuity in the links between childhood personality and adaptation across childhood into late adolescence.
