Perceptions and effectiveness of episodic future thinking as digital micro-interventions based on mobile health...

Area of Science:

• Behavioral Economics
• Cognitive Psychology
• Digital Health Interventions

Background:

• Delay discounting describes the human tendency to prefer immediate rewards over future benefits.
• Episodic future thinking (EFT) is an intervention designed to increase the perceived value of future rewards by mentally simulating future events.
• Mobile health (mHealth) offers a platform for delivering accessible, micro-interventions to address behavioral tendencies.

Purpose of the Study:

• To explore the feasibility of using mHealth technology to deliver EFT micro-interventions.
• To assess whether digital EFT micro-interventions can reduce delay discounting.
• To compare the effectiveness of regular EFT against goal-oriented EFT (gEFT) and gather user perceptions.

Main Methods:

• A 21-day randomized controlled study involving 208 participants.
• Participants were allocated to three groups: gEFT, EFT, or a control group.
• Data collection included measures of delay discounting and qualitative user perceptions.

Main Results:

• Combined intervention groups showed a significant reduction in delay discounting compared to the control group.
• Individually, only the EFT group demonstrated a statistically significant reduction in delay discounting.
• User perceptions suggested gEFT might be slightly more suitable for micro-interventions.

Conclusions:

• EFT delivered via mHealth micro-interventions can effectively reduce delay discounting.
• Future interventions should consider varied multimedia formats and user preferences for optimal engagement.
• Integrating EFT with other micro-interventions may enhance sustained user interest and effectiveness.
