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.
