Previous research has found concurrent and prospective associations between negative mood and body dissatisfaction; however, only experimental research can establish causal relationships. This study utilized an experimental design to examine the influence of negative mood on body dissatisfaction. Undergraduate women were randomly assigned to an experimental or control condition. Participants in the experimental condition (n = 21) completed a negative mood induction procedure. Participants in the control condition (n = 24) completed a neutral mood procedure. All participants completed visual analog scales regarding their mood and satisfaction with weight and shape before and after each manipulation. Body dissatisfaction increased following the procedure for experimental but not control participants, suggesting that negative mood caused increased body dissatisfaction. In cultures that idealize thinness, body dissatisfaction may arise from funneling general feelings of dysphoria into more concrete and culturally meaningful negative feelings about the body.

Negative affect is a prospective risk factor for the development of eating disorders (Stice, 2002). Further, acute increases in negative affect appear to be a trigger for binge eating among women with bulimia nervosa and binge eating disorder (Haedt-Matt & Keel, 2011). Thus, negative mood has both distal and proximal significance in disordered eating. Similarly, body dissatisfaction predicts the development of a variety of negative consequences, particularly eating pathology (Johnson and Wardle, 2005 and Stice, 2002). However, little is known about the causal relationship between these two risk factors. The purpose of this study was to examine the influence of negative mood on body dissatisfaction.
