Psychometric evaluation of biogenic versus psychogenic erectile dysfunction

Psychological test data, including the Minnesota Multiphasic Personality Inventory (MMPI), Symptom Check List (SCL-90R) and the Derogatis Stress Profile (DSP), was analyzed for male veterans who had been previously diagnosed as suffering from either psychogenic or biogenic erectile dysfunction. Consistent with previous studies, there were no significant differences found between the two groups on the MMPI profile scores and the selected research scales. However, there were also no differences found on either the SCL-90R or the DSP, further questioning the use of objective psychometric instruments in discriminating the etiology of sexual dysfunction.
