International Index of Erectile Function (IIEF)

Description: A condition measure of erectile functioning [1].

Format: 15 items assessing the participant’s overall sexual satisfaction in 5 domains: erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction.

A newer version of the IIEF, the IIEF-5 was developed by retaining only items with moderate or good discrimination ability between men with and without erectile dysfunction.

Scoring: Items on the IIEF are rated on the following scale:

5 = Almost always or always
4 = Most times (much more than half the time)
3 = Sometimes (about half the time)
2 = A few times (much less than half the time)
1 = Almost never or never
0 = No sexual activity OR Did not attempt intercourse OR No sexual stimulation. Certain items are rated on a scale from 1(very low) to 5 (very high).

Administration and Burden: Self-administered. Less than 15 minutes to complete.

Psychometrics for SCI: Preliminary evidence suggests the IIEF is a reliable and valid measure with good clinical utility for SCI [2 - 3].

Languages: The IIEF has been translated into 32 languages.

QoL Concept: This is a measure of overall sexual satisfaction, which corresponds to Box C (HrQoL, achievements) of Dijker’s Model.
