Family History and Alcohol Use Outcomes: Examining Transmission of Risk through Impulsivity and the Moderating Role of Organized Sports Participation.

BACKGROUND

College students are at risk for alcohol misuse and those who participate in organized sports are at even higher risk. Family history of alcohol problems (FH) and impulsivity are well-documented risk factors for alcohol use outcomes, but no research has examined the role of organized sports participation in moderating these associations. This study examined the associations between FH, alcohol consumption and alcohol use disorder (AUD) symptoms, the role of UPPS-P (Urgency, Premeditation, Perseverance, Sensation Seeking, Positive Urgency impulsive behavior scale) impulsivity dimensions in mediating the association between FH and alcohol use outcomes, and whether these associations vary by students' organized sports participation.

METHOD

Participants ( = 3,959, 64.7% female, 51.8% White; Mean age = 18.48 years, SD = .40) were recruited from a large, public university and completed an online survey in the fall and spring semesters of their first year in college. Path analyses were conducted in Mplus.

RESULTS

FH was associated with higher levels of alcohol consumption and more AUD symptoms. Lack of premeditation, lack of perseverance, and negative urgency partially mediated the associations between FH and alcohol consumption and AUD symptoms. The association between negative urgency and AUD symptoms was stronger for organized sports participants.

CONCLUSIONS

Impulsivity dimensions are risk factors for both alcohol consumption and AUD symptoms and serve as important pathways for the transmission of risk between generations. Prevention and intervention efforts aimed at reducing problematic alcohol use should target impulsivity generally, and particularly negative urgency among college students who participate in organized sports.
