Development and Evaluation of an Abridged IIEF-5 as a Diagnostic Tool for Erectile Dysfunction

Erectile dysfunction has received considerable increases in attention by primary care clinicians as awareness of its prevalence, quality of life consequences, and ultimate treat-ability become more widespread. The International Index of Erectile Function (IIEF) has been validated as being highly sensitive and specific for measuring treatment efficacy in erectile dysfunction. This tool is not designed for diagnostic use and is a bit unwieldy for office screening. To meet the need of a more simple office screening device, Rosen and colleagues developed an abbreviated questionnaire that was used in multicenter trials investigating sildenafil (Viagra) for erectile dysfunction. The sample of men (n = 1047) who were evaluated completed both the original and the abridged IIEF. A group of 115 men without erectile dysfunction served as controls. The five questions asked for responses on a five-point scale about: 1) confidence in getting and keeping an erection; 2) sufficiency of turgidity for penetrations; 3) adequacy for maintaining an erection after penetration; 4) difficulty in maintaining an erection during intercourse; and 5) overall level of satisfaction with intercourse.

The abridged IIEF was found to be a sensitive and specific diagnostic indicator of erectile dysfunction.
