Family history of alcohol abuse moderates effectiveness of a group motivational enhancement intervention in college women.

This study examined whether a self-reported family history of alcohol abuse (FH+) moderated the effects of a female-specific group motivational enhancement intervention with first-year college women. First-year college women (N=287) completed an initial questionnaire and attended an intervention (n=161) or control (n=126) group session, of which 118 reported FH+. Repeated measures ANCOVA models were estimated to investigate whether the effectiveness of the intervention varied as a function of one's reported family history of alcohol abuse. Results revealed that family history of alcohol abuse moderated intervention efficacy. Although the intervention was effective in producing less risky drinking relative to controls, among those participants who received the intervention, FH+ women drank less across five weeks of follow-up than FH- women. The current findings provide preliminary support for the differential effectiveness of motivational enhancement interventions with FH+ women.
