The Erection Hardness Score (EHS) is a one‐item questionnaire that assesses rigidity on a 4‐point scale. To perform a validation of a Spanish version of the EHS by comparison with the International Index of Erectile Function (IIEF) questionnaire. Validation of the EHS included: (i) professional translation of the scale; (ii) scientific evaluation of the translation from four independent urologists; (iii) assessment on five individuals to test correct comprehension and idiomatic adequacy (iv) validation of the EHS by a cross‐sectional, multicenter comparison with the IIEF. Patients were required to respond to a Spanish version of the EHS and IIEF. Statistic correlation was carried out between the EHS score and IIEF‐erectile function domain (EF) score. A total of 125 patients were recruited. Overall prevalence of erectile dysfunction (ED) by the EHS questionnaire was of 80.2% patients (n = 97). Mean EHS was 2.74 ± 0.97. Mean IIEF‐EF score was 17.4 ± 9.5. The EHS showed good reliability. The rate of missing responses to the EHS questionnaire was 0%. A one‐factor analysis of variance was performed between the EHS and EF subdomain of IIEF (P = 0.000). Pearson's correlation coefficient between EHS and EF subdomain of IIEF was 0.834, P < 0.01. The EHS is a reliable tool to test ED and its Spanish version was satisfactorily understood by patients and correlated with IIEF‐EF.
