This qualitative study aimed to assess the need for information in eating disorders from the perspective of relatives. Further, it examined the question how publicly available information about eating disorders may contribute to psychoeducation. Thirteen relatives of patients with anorexia nervosa and bulimia nervosa were interviewed based on a semistructured interview guide. The interview transcripts were interpreted by using a structuring qualitative content analysis. Relatives showed a high need for information throughout the entire course of illness. More information about the disorder itself and its potential treatment were requested. The needs were addressed to public services and to family doctors as well as paediatricians. Relatives as well as family doctors and paediatricians play an important role in the detection and support of the treatment of eating disorders. In view of the high rate of cases diagnosed late or not at all, psychoeducational offers require further expansion.
