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.
勃起硬度评分（EHS）是一种评估 4 点量表上硬度的单项问卷。
通过与国际勃起功能指数（IIEF）问卷比较，对西班牙版 EHS 进行验证。
EHS 的验证包括：（i）量表的专业翻译；（ii）四位独立泌尿科医生对翻译的科学评估；（iii）对五名个体进行评估，以测试正确的理解和惯用表达（iv）通过与 IIEF 的横断面、多中心比较来验证 EHS。
患者需要回答西班牙版 EHS 和 IIEF。EHS 评分与 IIEF-勃起功能域（EF）评分之间进行了统计学相关性分析。
共招募了 125 名患者。根据 EHS 问卷，勃起功能障碍（ED）的总患病率为 80.2%（n=97）。EHS 的平均得分为 2.74±0.97。IIEF-EF 评分的平均得分为 17.4±9.5。EHS 具有良好的可靠性。EHS 问卷的缺失率为 0%。对 EHS 和 IIEF-EF 亚域进行单因素方差分析（P=0.000）。EHS 与 IIEF-EF 亚域之间的 Pearson 相关系数为 0.834，P<0.01。
EHS 是一种可靠的工具，可以测试 ED，其西班牙版本得到了患者的充分理解，并与 IIEF-EF 相关。
