Continuity of difficult temperament in adolescence: Relations with depression,life events,family support,and substance use across a one-year period

This longitudinal study examined the continuity of temperamental difficulty among a school-based sample of middle adolescents (n=975) over a one-year period. Of the participants, 25% were classified as difficult at one or both measurement occasions and over 40% were classified as temperamentally discontinuous. Repeated measures multivariate analyses of covariance analyses identified mean differences in psychosocial functioning by temperamental continuity groups and by gender. Temperamental difficulty was associated with higher levels of depression, stressful life events, use of some substances, and lower levels of perceived family support. Gender differences were indicated for family support, depression, life events, and alcohol use.This research was supported in part by NIAAA Grant No. AA07861 awarded to Michael Windle.Received Ph.D. in human development and family studies from the Pennsylvania State University.
