Role of Risk Taking and Inhibitory Control in Alcohol Use Among Maltreated Adolescents and Nonmaltreated Adolescents.

Exposure to childhood maltreatment is a significant risk factor for the development and persistence of problematic alcohol use. The present study examined the role of risk taking and inhibitory control, key cognitive processes believed to govern behavioral regulation, as mechanisms that underlie the association between childhood maltreatment and the early stages of alcohol use. A sample of 129 maltreated adolescents and 102 socioeconomic status-matched, nonmaltreated adolescents and their parents completed three annual assessments, including computer-administered tasks and adolescent- and parent-report questionnaires, across ages 12-13 through 14-15 years. Childhood maltreatment was not directly associated with alcohol use in middle adolescence but was significantly associated with deficits in inhibitory control in early adolescence, which, in turn, led to significantly increased alcohol use in middle adolescence. Indeed, decreased inhibitory control was significant as a mediator, highlighting the salient role of this cognitive process in the early stages of alcohol use among maltreated adolescents.
