[Reliability and validity of the Chinese version of The Premature Ejaculation Diagnostic Tool].


OBJECTIVE To translate the English version of The Premature Ejaculation Diagnostic Tool (PEDT) into Chinese, evaluate its reliability and validity, and analyze its feasibility in the diagnosis of premature ejaculation (PE). METHODS Following the forward-backward translation procedure, we developed the Chinese version of PEDT, which was then revised by andrologists and bilingual linguists. We enrolled subjects with or without PE from 15 urological or andrological clinics in China and obtained the information about their demographic characteristics, PEDT scores, and intra-vaginal ejaculation latency time (IELT). We evaluated the internal consistency of PEDT using Cronbach alpha, was examined its reliability and stability by test-retest analysis, analyzed its correlation with IELT by Spearman correlation analysis, and tested its sensitivity and specificity by receiver operating characteristic ( ROC) analysis. RESULTS Totally, 570 PE patients (aged [30.66 ± 7.11] years) and 226 non-PE men (aged [33.01 ± 5.41] years) were recruited, with the mean IELT of (1.34 ± 0.54) min in the former and (11.09 ± 7.5) min in the latter group. The Cronbach's alpha of the Chinese version of PEDT was 0.79, and the test-retest correlation coefficient was 0.75 (P < 0.01). The PEDT score was negatively correlated with IELT (Spearman's p = -0.52, P < 0.01). When the cutoff value of PE diagnosis was defined as 7.5, the sensitivity and specificity of PEDT were 0.80 and 0.78, and when as 8.5, they were 0.72 and 0.89, respectively. CONCLUSION The Chinese version of PEDT was demonstrated to have good internal consistency, reliability, and validity, as well as a high predictability for PE. It can be used as a reliable and convenient tool to screen PE among Chinese men.
