Erectile dysfunction in men with chronic medical illness.

This study examined interrelationships of psychosocial variables found in a psychological evaluation for erectile disorder in 75 male veterans with chronic medical illness. Patients whose partners participated in the evaluation were compared with those whose partners were not involved, and agreement on measures between patients and partners was examined. Finally, a principal components analysis was performed to assess the primary dimensions underlying the variance in mental health and sexual functioning variables. Five factors were identified, accounting for 65.5% of the variance. Results of these analyses are discussed in order to obtain an understanding of the interrelationship between behavioral, psychological, and interpersonal variables in the onset and course of sexual dysfunction.
