Mechanisms of influence of body checking on binge eating / Mecanismos de influencia de las conductas de comprobación del cuerpo en los atracones

Despite the theorized role of body checking behaviours in the maintenance process of binge eating, the mechanisms by which they may impact binge eating remain unclear. Using objectification model of eating pathology as a theoretical framework, the authors examined the potential intervening roles of body shame, appearance anxiety, and dietary restraint in the pathway between body checking and binge eating. Data collected from a large sample of treatment-seeking people with Bulimic-type Eating Disorders (N = 801) were analysed trough structural equation modelling. Results showed that, regardless of specific DSM-5 diagnostic categories, body checking behaviours were indirectly associated with binge eating and dietary restraint through body shame and appearance anxiety, whereas dietary restraint was directly linked to binge eating. The findings have clinical utility as they contribute to gaining insight into how critical scrutiny of one's body may act in several indirect ways to affect binge eating. We discuss practical implications of the findings (AU)

A pesar del papel teórico que desempeñan las conductas de comprobación corporal en el proceso de mantenimiento de la conducta de atracón, los mecanismos por los que pueden afectar a los atracones siguen sin estar claros. Tomando el modelo de la objetivación de la patología alimentaria como marco teórico, los autores examinaron las posibles funciones que desempeñan la vergüenza corporal, la ansiedad por la apariencia y la restricción alimentaria en la comprobación del cuerpo y los atracones. Los datos recogidos en una amplia muestra de pacientes con trastorno de tipo bulímico en busca de tratamiento (N = 801) se analizaron a través de modelos de ecuaciones estructurales. Los resultados mostraron que, independientemente de las categorías diagnósticas específicas del DSM-5, las conductas de comprobación estaban asociadas indirectamente con los atracones y la restricción alimentaria a través de la vergüenza corporal y la ansiedad por la apariencia, mientras que la restricción alimentaria estaba directamente asociada con los atracones. Los resultados aportan utilidad clínica dado que contribuyen a la idea de cómo el examen crítico del propio cuerpo puede afectar de forma indirecta a las conductas de atracón. Se discuten las implicaciones prácticas de los hallazgos (AU)

Are the Male Body Dissatisfaction and Drive for Muscularity Scales reliable and valid instruments?

The Drive for Muscularity Scale and Male Body Dissatisfaction Scale were developed for use with men and correspond to measures of drive for thinness and body dissatisfaction in women. The psychometric properties of these measures were evaluated in a sample of 655 Italian men, who completed other 11 measures also. Both scales demonstrated excellent internal consistency and temporal stability as well as criterion-related and concurrent validity. Both measures distinguished between men with high and low levels of disordered eating. Confirmatory factor analysis replicated the unidimensional factor structure of both scales. Directions for future research are discussed.

Male body dissatisfaction and eating disorder symptomatology: moderating variables among men.

Body dissatisfaction is recognized as a robust risk factor for eating disorders. Despite over 80% of college men being body dissatisfied, not all men report several levels of eating disorder symptoms. In this study, we examined poor impulse control, social anxiety and internalization of media ideals as potential moderators. Data collected from 405 college-aged men were analysed, using latent variable structural equation modelling approach. All variables investigated have been found to moderate the body dissatisfaction-eating disorder symptomatology, such that male body dissatisfaction was strongly related to men's eating disorder symptomatology when each moderator was at its highest level. Practical implications are discussed.
