Prevention and early intervention in cases of anorexia and bulimia require that both professionals and the general public have knowledge about these eating disorders. A study was conducted to identify the questions about these disorders most often asked by the general public and to develop a guide to answer those questions for individuals of different ages and educational levels. The Eating Disorders Question Inventory, developed to allow respondents to ask questions in 11 categories, was completed by 147 females and 63 males. In general, the respondents were well-educated, professional, either Catholic or Jewish, and very interested in acquiring specific information about the nature, etiology, effects, and prevention of anorexia nervosa and bulimia. The results indicated that respondents repeatedly asked questions about social, psychological, cultural, and economic pressures on families and individuals, and how those pressures might make certain groups or individuals more susceptible to the onset of anorexia, bulimia, or related eating disorders. This study culminated in the development of a guide, based on a set of working definitions of anorexia nervosa and bulimia detailed in the Diagnostic Statistical Manual of Mental Disorders III. A list of the 30 most frequently asked questions from the survey is included. (NB)
