Binge eating symptoms as mediator between self-efficacy, alexithymia, anger, and anxiety in overweight and obese patients with cardiovascular disease

Weight control self-efficacy refers to one's perception that she or he can effectively engage in behaviours that will result in weight loss or maintenance. It may predict weight loss in obese populations. Obese persons with low weight control self-efficacy may feel frightened and discouraged by perceived discrepancies between actual and desired weight, while those with high self-efficacy intensify their efforts and perseverance in achieving intended weight. The aim of the current study is to investigate correlations among self-efficacy, alexithymia, binge eating, anxiety and anger in 100 patients with cardiovascular disorder and with different BMI (68 male ; mean age 55.6 years, mean BMI 32.07±3.58). The assumption was that binge eating mediated the relationship between self-efficacy on one side, and anxiety and anger on the other side. The self-report questionnaires designated to measure the weight-control self-efficacy, alexithymia, binge eating, anxiety, and anger as a trait and state were applied. Results indicated a significant negative correlation between self-efficacy, binge eating and anxiety. Obese persons with high self-efficacy expressed fewer binge-eating episodes and had lower anxiety level. Self-efficacy was positively correlated with weight control but not with anger expression. It means that those with higher weight control self-efficacy control better their anger. Women engaged more often in binge eating behaviour and they reported higher anxiety level compared with men. In general, results showed that obese patients with low self-efficacy were more prone to binge eating, and binge eating mediated anxiety and anger control. Results suggest that mentioned psychological and behavioural variables as well as gender peculiarity must be considered while applying cognitive-behavioural treatment directed to weight loss.
