An apparatus for the objective measurement of the conscious aspects of body image is described. The method involves photographing subjects and scanning the photograph with a video camera. The subject adjusts a control that varies the image on a television monitor to give a representative continuum from endomorphy through mesomorphy to ectomorphy without distorting height. A permanent photographc record of the subject's judgment can be taken. A permanent graphic record of the accuracy of the judgment and of the judgment time can be registered by a pen recorder as impulses from the control are relayed as the subject adjusts the dial. Data on the body image of a group of 60 obese females, 25 hospitalized anorexics, and 50 controls are presented. Implications for therapy and further research are discussed.
