Longitudinal associations between descriptive and injunctive norms on college drinking

Asymmetrical perceptions of tipping points in alcohol consumption: Lower perceived tolerance in oneself versus peer

Objective: The current study investigated how tipping points, a phenomenon in which an individual's threshold for perceiving a change has been exceeded, may be asymmetrical between self-tipping points and those applied to others and how experiences with alcohol affect these judgments. Participants: Undergraduates (N = 300). Methods: Participants reported their drinking frequency, quantity, and parental alcohol use, and evaluated tipping points by assessing how many drinks over the course of how many days they would perceive as problematic alcohol use in an online survey. Results: Participants, on average, reported lower tipping points indicative of problematic drinking behaviors for themselves, as compared to their peers. Results also revealed that quantity of alcohol consumption as well as parental alcohol use and participant age contributed to determining problematic consumption tipping points. Conclusions: Considerations should be given to how these tipping point judgments may affect drinking behaviors. Additionally, there is evidence that current consumption may cloud these judgments.

Normative Perceptions of Sexual Behavior and Alcohol Use among Bisexual Women

Background: As compared to heterosexual and lesbian women, bisexual women report higher rates of alcohol, other substance use, and risky sexual behavior, and they experience more negative outcomes from these behaviors. Descriptive norms (i.e., perceptions of others' behavior) are an important predictor of risky behaviors, but scant research has examined whether bisexual women's perceptions of other bisexual women's alcohol use and sexual behavior are associated with their own alcohol or drug use during sex. Objectives: Consequently, the present study examined (1) whether perceived sex norms were related to engagement in sex and (2) the relative influence of drinking and sex norms on engaging in sex while drinking among bisexual women. Method: Data were collected from 225 self-identified bisexual women who completed an online survey about their typical weekly alcohol use, engagement in alcohol or drug use during sex in the past 30 days, and normative perceptions of drinking and sexual behavior. Results: Regression models demonstrated both sexual norms and drinking frequency norms were positively associated with alcohol or drug use during sex. In addition, only perceived norms of other bisexual women, compared to perceived norms of lesbian and heterosexual women, predicted engagement in sex. Conclusions: Bisexual women may be susceptible to normative perceptions, given their connectedness to a marginalized social group. Thus, alcohol prevention and intervention efforts aimed at reducing risky consequences among bisexual women should specifically consider drinking and sexual norms of other bisexual women.
