||The Body Shape Questionnaire (BSQ) is a 34-item instrument desinged to measure concerns about body shape among young women. The BSQ is based on the notion that disturbance of body image is a central feature of both anorexia nervosa and bulimia. Although a number of assessment procedures have been developed that deal with various aspects of body image, the BSQ is one of the few measures that focus on concerns about body shape. This is especially important because concern about body shape is one of the key dimensions distinguishing the disorder of anorexia. In particular, the BSQ focuses on the phenomenological experience of “feeling fat”. The BSQ can be used for both assessment purposes and to evaluate response to treatment.
