Using a prospective design, this study examined (a) whether hyperactiv
e children suffer from low self-esteem as adolescents; (b) whether low
self-esteem is associated with poor functioning in adolescence; (c) w
hether hyperactive children exhibit a positive illusory bias, in which
self-esteem is independent of level of functioning; and (d) whether s
elf-esteem in adolescence is associated with poor functioning in adult
hood. Subjects were 65 children diagnosed as hyperactive in childhood,
and 62 matched controls sampled from a medical clinic. After controll
ing for current mental disorder the hyperactive cohort reported lower
self-esteem in adolescence, was judged by clinicians to have lower lev
els of overall adjustment in adolescence, and had lower educational ac
hievement and occupational rank in adulthood, as compared to controls.
