Use of single-question screening for erectile dysfunction: a study of at-risk Asian men in primary health care.

ABSTRACT

This study assesses the validity of a single-question screener for erectile dysfunction (ED) in men at risk in comparison to a standard validated tool - the five-item version of the International Index of Erectile Function (IIEF-5). A total of 174 men with at least one risk factor for ED were studied, with 58.0% and 10.9% of the study respondents meeting the criteria for their erectile impairment by IIEF-5 and single-question screener respectively. Our results suggest that in spite of high feasibility, a simplified, single-question screener has low sensitivity in capturing ED prevalence, even in an at-risk population, within the Asian context.
