Episodic future thinking reduces delay discounting among persons who use e-cigarettes.

Abstract

There has been an alarming increase in e-cigarette dependence among young adults, many of whom would like to quit vaping nicotine but are finding it difficult to do so. Episodic future thinking (EFT), a cognitive intervention involving imagining future events, has been shown to reduce cigarette craving, demand intensity, and self-administration among cigarette smokers but has not been tested with e-cigarette users. This study tested if a brief EFT intervention decreases delay discounting and smoking choice using a within-subjects experimental design administered via Zoom. Daily young adult e-cigarette users attended a baseline session and two counterbalanced experimental sessions: (a) EFT in which participants preexperienced and described positive future events and (b) standardized episodic thinking, a control intervention in which participants described their experiences watching three short videos. Measures of craving, mood, and delay discounting across three commodities: Money, e-cigarette products, and food were completed pre- and postmanipulation. As predicted, monetary delay discounting showed a greater decrease following EFT relative to standardized episodic thinking (p = .006; η_p² = .229). There were no effects on craving or mood. Participants also completed a 40-min vaping versus money choice task. Approximately 70% of participants chose to abstain for the full 40 min after EFT compared to 60% after the control condition, a nonsignificant difference (p = .184). Additional research is needed to support the efficacy of EFT as an intervention for helping e-cigarette users increase their ability to abstain. The study demonstrates the feasibility of conducting experimental research on e-cigarettes in a virtual setting. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
