The use of a positive mood induction video-clip to target eating behaviour in people with bulimia nervosa or binge eating disorder: An experimental studyCardi, Valentina; Leppanen, Jenni; Leslie, Monica; Esposito, Mirko; Treasure, Janet; King's College London; University College LondonRecent theoretical models and empirical research have indicated that momentary negative affect increases the likelihood of binge eating episodes for individuals with bulimia nervosa and binge eating disorder. However, relatively little research has explored the potential for positive mood to serve a protective effect in reducing the likelihood of overeating behaviour in bulimia nervosa and binge eating disorder. The current study included 30 women with bulimia nervosa or binge eating disorder in a within-subjects crossover design. Following exposure to a video designed to induce food craving, we found that a positive mood vodcast was associated with significantly lower levels of negative mood and food consumption in a taste test meal, when compared to a neutral vodcast (p = .002). These findings support a role for decreasing negative mood in reducing the likelihood of binge eating behaviour in women with bulimia nervosa and binge eating disorder.
