In a thorough review of literature of eating disorders in men, it is consistently shown that symptom presentation varies greatly by gender. However, almost all eating disorder instruments have been developed and validated on females. These critical differences between men and women in symptom presentation provoke the necessity to develop a male specific eating disorder assessment tool. The development of the EDAM is described, and in a study of 108 clients of residential treatment facilities, results of the preliminary version of the EDAM are shown. Internal consistency reliability is supported and factor analysis loadings are provided. Results from a logistical regression support the EDAM's ability to predict eating disorders in men.
