Examining social attention as a predictor of problem drinking behavior: A longitudinal study using eye-tracking

Abstract

Background

Researchers have long been interested in identifying objective markers for problem drinking susceptibility informed by the environments in which individuals drink. However, little is known of objective cognitive-behavioral indices relevant to the social contexts in which alcohol is typically consumed. Combining group-based alcohol administration, eye-tracking technology, and longitudinal follow-up over a 2-year span, the current study examined the role of social attention in predicting patterns of problem drinking over time.

Methods

Young heavy drinkers (N = 246) were randomly assigned to consume either an alcoholic (target BAC 0.08%) or a control beverage in dyads comprising friends or strangers. Dyads completed a virtual video call in which half of the screen comprised a view of themselves (“self-view”) and half a view of their interaction partner (“other-view”). Participants' gaze behaviors, operationalized as the proportion of time spent looking at “self-view” and “other-view,” were tracked throughout the call. Problem drinking was assessed at the time of the laboratory visit and then every year subsequent for 2 years.

Results

Significant interactions emerged between beverage condition and social attention in predicting binge drinking days. In cross-sectional analyses, among participants assigned to the control (but not alcohol) group, heightened self-focused attention was linked with increased binge days at baseline, B = 0.013, Exp(B) = 1.013, 95% CI = [0.004, 0.022], p = 0.005. In contrast, longitudinal models indicated that heightened self-focused attention among control participants while interacting with friends was linked with a more pronounced decline in binge drinking over time.

Conclusions

The relationship between social attention and problem drinking is complex and evolves over time. While dispositional self-consciousness may act as a risk factor at the cross-sectional level, it appears to serve a potentially protective function as participants mature into young adulthood. More broadly, results highlight potential utility for objective markers of self-consciousness in the understanding of problem drinking etiology.
