Premature ejaculation (PE) is the most prevalent male ejaculation disorder. The premature ejaculation diagnostic tool (PEDT) was developed to systematically apply the DSM-IV-TR criteria in diagnostic PE.
To evaluate the diagnostic value of the PEDT and its association with intravaginal ejaculatory latency time (IELT).
(i) Korean validation of PEDT: data was collected from men interviewed by one of the two clinical experts, who made a diagnostic of present or absence of PE, using DSM-IV-TR criteria. A total of 103 patients with PE and 100 men without PE were enrolled into the study and requested to complete the PEDT; and (ii) The correlation between IELT and PEDT: 200 participants were enrolled and each participant was asked to make out PEDT. All participants were requested to measure IELT.
Validity and reliability of the PEDT and its association with IELT.
The geometric mean IELT of the PE group was 115.37 ± 78.14 seconds. The number of men reporting IELTs of <1, 1 to ≤ 2, and >2 minutes were 28 (28.6%), 29 (29.6%), and 41 (41.8%), respectively. The Cronbach's alpha score was calculated as 0.93, showing adequate internal consistency. The test-retest correlation coefficients of each item were higher than 0.72 and the correlation coefficients of the total score was 0.88. (P < 0.001) Sensitivity and specificity analyses suggested a score of ≤ 8 indicated no PE, 9 and 10 probable PE, and ≥ 11 PE. The PEDT total score and IELT showed an adequate negative correlation. (ρ = -0.77, P < 0.0001) also, the PEDT total score of the PE subgroup (IELT ≤ 2 minutes) and IELT showed a negative correlation. (ρ = -0.6, P < 0.0001)
The PEDT was highly effective in detecting the presence of PE. The result of our study supports its validity as a diagnostic tool in the clinical setting.
早泄（PE）是最常见的男性射精障碍。早泄诊断工具（PEDT）的开发是为了系统地应用 DSM-IV-TR 标准来诊断 PE。
评估 PEDT 的诊断价值及其与阴道内射精潜伏期时间（IELT）的关系。
（i）PEDT 的韩国验证：从由两位临床专家之一访谈的男性中收集数据，临床专家根据 DSM-IV-TR 标准做出是否存在 PE 的诊断。共有 103 名 PE 男性和 100 名非 PE 男性被纳入研究，并要求他们完成 PEDT；（ii）IELT 与 PEDT 的相关性：共纳入 200 名参与者，每位参与者都被要求完成 PEDT。所有参与者都被要求测量 IELT。
PEDT 的有效性和可靠性及其与 IELT 的关系。
PE 组的几何平均 IELT 为 115.37±78.14 秒。报告 IELT<1、1 至≤2 和>2 分钟的男性人数分别为 28（28.6%）、29（29.6%）和 41（41.8%）。Cronbach's alpha 评分计算为 0.93，显示出足够的内部一致性。每个项目的测试-重测相关系数均高于 0.72，总分的相关系数为 0.88（P<0.001）。（P<0.0001），PEDT 总分和 IELT 呈负相关。（ρ=-0.77，P<0.0001），PE 亚组（IELT≤2 分钟）的 PEDT 总分和 IELT 也呈负相关。（ρ=-0.6，P<0.0001）
PEDT 非常有效地检测出 PE 的存在。我们的研究结果支持其作为临床诊断工具的有效性。
