آیا نارضایتی از بدن دارای معانی مشابه برای مردان و زنان است؟ مطالعه ناپذیری اندازه گیری

Objectives The aim of this study was to assess the psychometric equivalence of body dissatisfaction (BD) between males and females. Method Two scales, BD and Drive to Thinness (DT), from the Eating Disorder Inventory-3 were evaluated. The sample was comprised of 1616 adolescent males and 1429 adolescent females. Factorial invariance across gender of two scales was assessed in order to evaluate the equivalence of scores. Results The results showed full invariance for the DT scale items, and partial invariance for BD scale items. The content analysis of the items confirmed that items related to the perception of thighs, stomach and hips showed differential functioning across gender. Conclusions Different representation of the BD construct between males and females was concluded, and caution was recommended in assessing and interpreting BD in male samples with questionnaires designed for women.

Although studies on eating disorders and related risk factors for body dissatisfaction (BD) have traditionally focused on women (Cohen, 2006; Stice, Nathan, & Durant, 2011; Woodside et al., 2001), recent epidemiology and community studies have reported on the incidence and prevalence of both disorders in the male population (Heinberg & Kraft, 2007). The European Study of the Epidemiology of Mental Disorders (ESEMeD; Preti et al., 2009) found that lifetime prevalence of anorexia nervosa, bulimia nervosa and binge eating is 1.22% for males and 3.73% for females. In a review of epidemiology studies conducted in the United States and Europe, Hoek and van Hoeken (2003) reported the prevalence rate of anorexia nervosa of eight per 100,000 in young women and one per 100,000 in men. As for BD, the data for the female population revealed a prevalence of more than 50% in the female population and more than 35% in the male population (Al Sabbah et al., 2009).
