Perceived willpower self-efficacy fluctuates dynamically with affect and distress intolerance

Abstract

People may experience subjective shifts in their self-efficacy for exerting willpower over time and based on context, and people who struggle with self-control may be particularly vulnerable to willpower self-efficacy fluctuations. Across four samples (college students without borderline features: n = 49; borderline features group: n = 50; current smokers: n = 61; chronic dieters: n = 92), participants completed one week of ecological momentary assessment (EMA) where momentary self-efficacy for willpower, positive affect, negative affect, tiredness, and distress intolerance were assessed randomly seven times per day. Results revealed that higher willpower self-efficacy was associated with lower negative affect and greater positive affect, and, lower willpower self-efficacy predicted subsequent distress intolerance via time-lagged analyses for the borderline features group.
