Development of the male function profile/impotence questionnaire

This paper describes three studies conducted to develop the Male Function Profile/Impotence Questionnaire as well as the psychometric properties of the instrument. The questionnaire is computer scored and, based on an interactional model, differentiates between organogenic and psychogenic causes for erectile dysfunction. Each subject is assigned one of 21 impotence profiles. Additional work-up recommendations are based on a breakdown and narrative describing all medical and psychological factors which bear on the subject's impotence.
