Changing University Students' Habit Strength Towards Alcohol Consumption Using Affectively and Cognitively Framed...

Area of Science:

• Psychology
• Health Behavior
• Intervention Studies

Background:

• Excessive alcohol consumption (EAC) among university students poses significant health risks.
• Habitual alcohol use is a key factor contributing to EAC in this population.

Purpose of the Study:

• To evaluate the efficacy of different attitude-salient messages in reducing habitual excessive alcohol consumption.
• To investigate the moderating roles of message framing (affective vs. cognitive), temporal focus (short-term vs. long-term), and individual differences (Need for Cognition, gender) in message effectiveness.

Main Methods:

• A randomized controlled trial involving 755 university students.
• Participants were assigned to one of five conditions: short-term affective, short-term cognitive, long-term affective, long-term cognitive, or a no-message control group.
• Habitual alcohol consumption strength was measured using the Self-reported Habit Index at baseline and follow-up.

Main Results:

• Significant interactions were found, indicating personalized message effectiveness.
• For men low in Need for Cognition (NfC), affective distal messages were most effective in reducing EAC habits.
• For women low in NfC, affective proximal messages were most effective. For individuals high in NfC (both genders), cognitive messages were superior in reducing EAC habits.

Conclusions:

• Message tailoring based on affective/cognitive framing, temporal focus, and individual characteristics (NfC, gender) is crucial for behavior change interventions.
• These findings have important implications for designing targeted public health information campaigns to modify alcohol consumption behaviors.
