[Structural equation model in the study of risk factors in the maintenance of binge eating].
This study investigated, in a sample of 483 adolescent girls, a number of risk factors associated with Binge Eating (BE) disorder, i.e. negative feelings, dieting behaviour, social influence and body dissatisfaction. Participants completed the following questionnaires: Bulimia Test, Depression Questionnaire, Dieting Self-Efficacy Measure, Dieting Success, Dieting Status Measure, Dutch Eating Behavior Questionnaire, Eating Disorder Inventory, Positive and Negative Affect Scale Revised, Rosenberg Self-Esteem Scale and Socio-cultural Attitudes Towards Appearance Questionnaire. Structural equation modeling was used in the data analysis to verify the hypothesized relations among the variables, with the aim of identifying the main predictors of BE. This methodology explains the correlation between the considered variables, and determines, using quantitative good fit indexes, both the strength of the correlations and the plausibility of the causal links between the hypothesized factors. Our findings confirm that negative feelings (Negative Affect) are the primary predictor for the maintenance of BE and highlight the significant role played by Social Influence. While Dieting Behaviour is not a primary predictor for the maintenance of BE it appears to influence it through its link with Negative Affect.
