The mediating effect of eating self-efficacy on the relationship between emotional arousal and overeating in the treatment-seeking obese.

In this study, we tested the proposition that the emotion-based eating of obese individuals is mediated by the effects of emotional arousal tendencies on brittle dieting self-restraint. Our indices of emotion-aroused eating, overeating, and brittle restraint were derived from a set of measures administered to 632 female and 254 male participants in a residential weight control and lifestyle change program. Mediation analyses indicated that (a) the relationship between positive emotion and overeating was entirely mediated by restraint tendencies and (b) the relationship between negative emotion eating and overeating was only partially mediated by brittle restraint. These findings held for both males and females. The results are discussed in relation to the viability of the psychosomatic hypothesis for understanding the relationship between emotions and overeating.

Psychological symptoms are greater among weight cycling women with severe binge eating behavior.

OBJECTIVE: To identify psychological characteristics and eating behaviors associated with weight cycling and binge eating behaviors in overweight women (body mass index > 27.3). DESIGN: Questionnaires measuring self-esteem, self-efficacy, coping strategies, psychological symptoms, depression, binge eating, restrained eating, disinhibition, and hunger were administered to female weight cyclers who were overweight. Psychological characteristics were compared between subjects grouped by binge eating disorder classification and by binge eating severity. SUBJECTS: A convenience sample of 62 female weight cyclers who were overweight was recruited from the Chicago, Ill, area. Questionnaires were administered individually or in small groups in subjects' homes or other private settings. STATISTICAL ANALYSES: Student's t tests or Mann-Whitney U tests were used to assess differences in psychological characteristics. RESULTS: Thirty-six weight cyclers (58%) met the criteria for binge eating disorder and 26 (42%) did not. Weight cyclers with binge eating disorder reported greater severity of binge eating (P < .0005) and disinhibition (P < .0005) and poorer eating self-efficacy (P < .0005) than weight cyclers without binge eating disorder. Weight cyclers with severe binge eating behaviors reported greater psychological distress (P < .0005) and depression (P < .005) and lower self-esteem (P = .0001) and used less healthful coping strategies (P = .0027) than weight cyclers with no binge eating to moderate binge eating problems. Weight cyclers with severe binge eating behavior also reported more hunger (P < .0005) and used less cognitive restraint (P = .0024) than those with no binge eating to moderate binge eating problems. APPLICATIONS: Operational definitions of weight cycling and binge eating are needed to facilitate research on effective weight-loss treatments. Persons seeking to lose weight (especially weight cyclers) should be assessed for binge eating severity, problematic eating behaviors, and psychological symptoms.
