Stress and episodic future thinking: Effects on temporal window and alcohol demand

Area of Science:

• Behavioral Economics
• Psychology
• Neuroscience

Background:

• Stress exacerbates problematic alcohol use by promoting short-term thinking.
• Episodic future thinking (EFT) counters short-term thinking by engaging future event imagination.
• EFT may reduce alcohol demand, particularly under high stress, by targeting this mechanism.

Purpose of the Study:

• To examine the relationship between stress, immediate reward preference, and alcohol demand.
• To assess the impact of EFT on immediate reward preference and alcohol demand.
• To determine if EFT is more effective in reducing alcohol demand under high stress conditions.

Main Methods:

• 139 adults with problematic alcohol use completed online surveys and tasks.
• Measures included stress levels, episodic future thinking (EFT) or episodic recent thinking (ERT) procedure, delay discounting, and alcohol purchase tasks.
• Correlations and path analyses investigated the interplay of stress, EFT/ERT, delay discounting, and alcohol demand.

Main Results:

• Higher baseline stress correlated with a greater preference for immediate rewards.
• EFT intervention increased preference for delayed rewards, leading to reduced alcohol demand.
• Stress did not moderate the effect of EFT on delay discounting.

Conclusions:

• EFT reduces alcohol demand by promoting delayed rewards, irrespective of stress levels.
• EFT's efficacy in reducing alcohol demand is not uniquely enhanced by higher stress.
• Findings highlight the distinct roles of stress and EFT in the behavioral economics of alcohol use.
