Validation of the Greek version of the Accommodation and Enabling Scale for Eating Disorders (AESED)

Eating disorders-related research has shown that families, in order to alleviate family conflict and stress, accommodate the symptoms of individuals with eating disorders. It has been argued that by tolerating or alleviating symptoms, the latter may gradually be reinforced or even fully accepted, as the family becomes increasingly "trapped" in specific eating patterns, weight control behaviors, and body shape worries. The Accommodation and Enabling Scale for Eating Disorders was created in 2009, aiming to assess family adaptability of individuals with eating disorders. The purpose of the present research was to test the psychometric properties of the Greek version of the scale in a sample of parents of individuals with eating disorders. The translation procedure was carried out based on the forward-backward method, while the study was conducted at the Eating Disorders Clinic of the First Psychiatric Clinic of Aiginiteion Hospital. The convenience sampling methods were used for the sample's recruitment. Respondents reported on their basic demographic characteristics, and completed the General Health Questionnaire-28, and the Accommodation and Enabling Scale for Eating Disorders. The final study's sample consisted of 125 parents of individuals with eating disorders (69.6% women), with a mean age of 55.2 years. Factor analysis revealed a five-factor model, similar to that of the original version of the scale, with the model explaining 63.3% of the total variance. Internal consistency was judged to be high, with Cronbach's coefficient a being 0.93 for the scale's total score, while Cronbach's α for the five subscales ranged from 0.78 to 0.90. Convergent validity was tested with the Spearman's coefficient rho, which revealed a statistically significant correlation of the weighted scale with the General Health Questionnaire (rho=0.33, p<0.5). The results showed that the Greek version of the Accommodation and Enabling Scale for Eating Disorders is a valid and reliable tool for assessing the adaptability of families of people suffering from eating disorders. Application of the tool to larger samples will validate its psychometric properties on a larger scale.
