Abstract
Having instruments validated in Chile for Erectile Dysfunction (ED), motivated the validation of the Spanish version of the International Index of Erectile Function (IIEF), in Chilean population. A non-experimental quantitative study of non-probabilistic sample was carried out for convenience, with 95 adult males from three health centers (Concepción, Talcahuano and Santiago), during November 2012 and June 2013. Blind experts conducted a clinical interview using DSM-V criteria and medical-surgical causes of ED. After the pilot application and adaptation of the IIEF, version IIEF-Ch was achieved by applying it to the entire sample. The results were analyzed with SPSS 15.0, obtaining high correlation between variables (X2: 956,533) and high sample adequacy (0,893); two factors that explain 81.59% of the variance of the instrument, with high reliability (.971) and adequate criterion validity, high sensitivity (84.5%) and acceptable specificity (91.9%). The IIEF-Ch is a valid and reliable instrument for studies on ED in Chile.
