Using confirmatory factor analysis, the 5-factor structure was confirmed. The scale demonstrated reliability, criterion validity, and measurement invariance across relationship status and generational cohorts. Findings support the IIEF’s use in South American clinical and research settings for assessing male sexual function and dysfunction.application/pdfDisfunción eréctilPsicometríaInvarianza de mediciónSatisfacción sexualChileHombresAnalysis of the International Index of Erectile Function: psychometric evidence and measurement invariance across relationship status and age generations in a Chilean sampleArticulo de revista10.1093/sexmed/qfae084
