The relationship between placebo alcohol and affect: motives for drinking

Area of Science:

• Psychology
• Neuroscience
• Affective Science

Background:

• Alcohol is often used to cope with negative affect, but can worsen depressive symptoms.
• The relationship between alcohol, affect, and drinking motives requires further clarification.
• Expectations about alcohol's effects play a role in its perceived benefits.

Purpose of the Study:

• To investigate if placebo alcohol blunts affective responding after negative experiences.
• To examine if the desire to drink increases in individuals expecting alcohol to aid coping.
• To explore alterations in drinking motives following negative mood induction.

Main Methods:

• Participants received either a soft drink or placebo alcohol.
• Mood was induced through neutral or negative conditions.
• Drinking motives were assessed before and after mood induction.

Main Results:

• Placebo alcohol did not significantly reduce affective responding.
• Desire to drink did not increase post-negative mood induction for those with coping motives.
• Coping-depression and enhancement motives decreased; participants misattributed mood causes.

Conclusions:

• Drinking motives are malleable and can be altered through learning, supporting expectancy challenge.
• The study provides evidence for alcohol's influence on emotional lability.
• Expectancy effects and motive modification are key areas for future research.
