This study details the further validation of the Premature Ejaculation Diagnostic Tool (PEDT), a five-item tool, developed to systematically apply the Diagnostic and Statistical Manual of Mental Disorders, revised version 4 (DSM-IV-TR), criteria in diagnosing presence or absence of premature ejaculation (PE). A total of 102 men completed the PEDT and were then interviewed by one of the seven clinical experts, who made a diagnosis of presence or absence of PE. The diagnoses from these two methods were compared to assess the convergent validity of PEDT. Retest reliability was also assessed, by men completing the PEDT a second time, approximately 2 weeks after the first administration. The level of agreement between clinical expert and PEDT diagnoses was very high (kappa-statistic=0.80 (95% CI=0.68-0.92)), and retest reliability was very good - Intraclass correlation coefficient=0.88. In summary, the PEDT is extensively validated, self-report measure that can systematically assess DSM-IV-TR criteria to provide accurate diagnoses of PE/no-PE.
本研究详细介绍了早泄诊断工具（PEDT）的进一步验证情况。PEDT是一个包含五个条目的工具，旨在系统应用《精神疾病诊断与统计手册》第四版修订版（DSM-IV-TR）的标准来诊断早泄（PE）的有无。共有102名男性完成了PEDT测试，随后由七名临床专家之一对他们进行访谈，专家对其是否患有PE做出诊断。将这两种方法得出的诊断结果进行比较，以评估PEDT的收敛效度。还通过让男性在首次测试约两周后再次完成PEDT来评估重测信度。临床专家诊断与PEDT诊断之间的一致性水平非常高（kappa统计量=0.80（95%可信区间=0.68-0.92）），重测信度也非常好——组内相关系数=0.88。总之，PEDT是经过广泛验证的自我报告测量工具，能够系统评估DSM-IV-TR标准，以准确诊断PE/非PE。
