title: The International Index of Erectile Function: a methodological critique and suggestions for improvement.
abstract: The International Index of Erectile Function is a well-worded and psychometrically valid self-report questionnaire widely used as the standard for the evaluation of male sexual function. However, some conceptual and statistical problems arise when using the measure with men who are not sexually active. These problems are illustrated using 2 empirical examples, and the authors provide recommended solutions to further strengthen the efficacy and validity of this measure.
