Social-norms interventions for light and nondrinking students

Area of Science:

• Public Health
• Psychology
• Substance Abuse Prevention

Background:

• Social-norms approaches are effective for alcohol prevention by correcting misperceptions of peer drinking prevalence.
• Existing interventions primarily target heavy-drinking students, leaving a gap for abstaining or light-drinking populations.

Purpose of the Study:

• To evaluate the impact of two online social-norms interventions on abstaining or light-drinking college students.
• To assess the moderating role of identification with other students in intervention effectiveness.

Main Methods:

• A study involving 423 freshmen and sophomore college students who reported low alcohol consumption.
• Random assignment to personalized-norms feedback, social-norms marketing ads, or an attention control group.
• Analysis using generalized linear mixed models to assess intervention effects.

Main Results:

• Both online interventions showed some positive effects on alcohol consumption perceptions.
• Social-norms marketing ads demonstrated stronger efficacy, especially for students with higher peer identification.
• Personalized-norms feedback also yielded benefits, though less pronounced than marketing ads.

Conclusions:

• Online social-norms marketing ads are a promising strategy for preventing alcohol misuse in light-drinking college students.
• Interventions tailored to student identification with peers may enhance prevention program effectiveness.
• Further research should explore optimizing social-norms interventions for diverse student drinking patterns.
