How does disgust regulate social rejection? a mini-review.

The need to belong is a fundamental aspect of human nature. Over the past two decades, researchers have uncovered many harmful effects of social rejection. However, less work has examined the emotional antecedents to rejection. The purpose of the present article was to explore how disgust--an emotion linked to avoidance and social withdrawal--serves as an important antecedent to social rejection. We argue that disgust affects social rejection through three routes. First, disgust encourages stigmatization, especially of those who exhibit cues of infectious disease. Second, disgust and disease-avoidance give rise to cultural variants (e.g., socially conservative values and assortative sociality), which mitigate social interaction. Third, when the self is perceived as a source of contamination, it promotes shame, which, subsequently, encourages withdrawal from social interaction. Directions for future research are also discussed.

A matter of perspective: The convergent and incremental validity of informant-reported drinking motives.

INTRODUCTION: Drinkers have social and affective reasons for using alcohol ('drinking motives'). Historically, drinking motives are self-reported. Informant-reports of drinking motives may be useful in corroborating self-report data. Thus, we investigated the correspondence between self- and informant-reports of drinking motives and the incremental validity of informant-reported motives in predicting targets' future alcohol problems. METHODS: Measures were completed by 174 university-aged, same-sex drinking buddy dyads (66% women) across two waves separated by 30 days. Dyad members who contacted study organisers were treated as targets, and their buddies as informants. Targets self-reported their own drinking motives at baseline, as well as their own alcohol problems at baseline and 30 days later. Informants reported on targets' drinking motives at baseline. RESULTS: Self- and informant-reports of targets' internal drinking motives (coping-depression and enhancement) showed significant, small positive correlations. Informants-reports of these same internal drinking motives (as well as coping-anxiety) predicted change in targets' alcohol problems over time, thereby providing additional predictive validity beyond that provided by targets' self-reports. DISCUSSION AND CONCLUSIONS: We encourage incorporating informant-reported internal drinking motives when assessing risk for escalating problem drinking in emerging adult drinkers.

Drinking to keep pace: A study of the moderating influence of extraversion on alcohol consumption similarity in drinking buddy dyads.

Heavy drinking in college remains a concerning issue due to its association with both health and social risks. While modelling contributes to college students' alcohol use, little work has identified who might be most susceptible to modelling effects. Peterson, Morey, and Higgins (2005) found males high in extraversion were more susceptible than others to matching strangers' drinking levels in a lab-based social drinking context. We sought to replicate and extend these findings by examining the impact of extraversion on social matching of alcohol consumption levels of a drinking buddy in college students' real lives. First, a significant relationship between buddy and target drinking levels was predicted in dyadic drinking situations. Additionally, we hypothesized that target extraversion would positively moderate this buddy- target drinking levels relationship. Data from 149 college student targets (74% F) and their same-sex drinking buddy were collected through online questionnaires examining targets' extraversion levels, and the drinking levels and social drinking context of both dyad members through a 30-day Timeline Followback measure. Linear mixed-effects modelling confirmed the study's first social matching hypothesis, while also revealing that target extraversion positively moderated the relationship between buddy and target daily drinking levels in dyadic drinking contexts. Findings extend those of Peterson et al. (2005) to a real-world (vs. lab-based) context, modelling of a buddy's (vs. stranger's) drinking levels, and a sample including women (vs. all-male). Results provide novel information on extraversion's contributions to modelling of alcohol use that may guide useful modifications to personality-based interventions for reducing college student heavy drinking.
