Background The premature ejaculation diagnostic tool (PEDT) is a brief, multidimensional validated instrument devised for diagnosing premature ejaculation (PE). However, there is insufficient evidence regarding its ability to differentiate subgroups of PE. We assessed the ability of the PEDT to differentiate four subgroups of PE (lifelong, acquired, variable and subjective PE).
An internet-based survey was conducted with a population-based sample of males aged 20-59 years. Participants were asked to complete a questionnaire requesting detailed medical and sexual histories. The questionnaire including questions from the PEDT and from the Medical Outcome Study Short-form 36-Item Health Survey (SF-36). Using the PEDT, PE was defined as a cutoff score of ≥11.
In this study, 443 subjects (mean age 39.3±10.1 years) were included. PEDT-PE prevalence was 14.6%. The proportions of PE subgroups and their mean PEDT scores were: lifelong PE, 2.9% and 15.5; acquired PE, 7.0% and 11.2; variable PE, 7.4% and 10.4; subjective PE, 3.2% and 9.0. PEDT scores were significantly higher in the lifelong PE group than in other the subgroups of PE (P<0.001). The subjective PE group had the lowest PEDT score, and their physical and mental component scores for the SF-36 were similar to those of non-PE subjects.
This population-based cross-sectional survey has demonstrated that the PEDT is not appropriate for research into four subgroups of PE when used in an general male population study, unless the PEDT is combined with an additional questionnaire with specific questions on the four PE subgroups.
背景 早泄诊断工具（PEDT）是一种简短的、经过多维度验证的用于诊断早泄（PE）的工具。然而，关于其区分早泄亚组的能力，证据并不充分。我们评估了PEDT区分四种早泄亚组（终身性、获得性、变异性和主观性早泄）的能力。
对年龄在20 - 59岁的男性进行了一项基于人群的网络调查。参与者被要求完成一份问卷，询问详细的医疗和性病史。问卷包括来自PEDT和医学结果研究简表36项健康调查（SF - 36）的问题。使用PEDT，将早泄定义为截断分数≥11。
本研究纳入了443名受试者（平均年龄39.3±10.1岁）。PEDT诊断的早泄患病率为14.6%。早泄亚组的比例及其平均PEDT分数分别为：终身性早泄，2.9%和15.5；获得性早泄，7.0%和11.2；变异性早泄，7.4%和10.4；主观性早泄，3.2%和9.0。终身性早泄组的PEDT分数显著高于其他早泄亚组（P<0.001）。主观性早泄组的PEDT分数最低，其SF - 36的身体和心理成分分数与非早泄受试者相似。
这项基于人群的横断面调查表明，在一般男性人群研究中，PEDT不适用于对四种早泄亚组的研究，除非将PEDT与一份针对四种早泄亚组的特定问题的附加问卷相结合。
