USE OF THE FLORIDA SEXUAL HISTORY QUESTIONNAIRE TO DIFFERENTIATE PRIMARY ORGANIC FROM PRIMARY PSYCHOGENIC IMPOTENCE

A recent study demonstrated the Florida Sexual History Questionnaire (FSHQ) is reliable and valid when used to discriminate impotent from nonimpotent men. This study examined the ability of the FSHQ to discriminate between men with primary psychogenic and primary organic impotence in a sample of impotent diabetics and a larger group of impotent men. The hit rate in the diabetic sample was 81% using an eight-item discriminant function, and 70% using the total score. Hit rates in the larger sample were significant but lower (73% and 66%). The results suggest that the FSHQ has concurrent validity in terms of discriminating primary organic from primary psychogenic impotence.
