One aspect of normative development is the achievement of appropriate selfregulation of affect. The ability to recover from dysphoric, sad affect, or mood repair, which is one component of affect regulation, is clearly impaired in depressed youths. Importantly, impaired mood repair may characterize children at familial risk for depression. This presentation will summarize literature supporting a likely link between mood-repair difficulties and subsequent depression in youngsters as well as the treatment and prevention implications of these findings.
