The role of bother/distress in the diagnosis of premature ejaculation (PE) has received minimal investigation compared with the 2 other diagnostic criteria, ejaculatory control and ejaculatory latency (EL).
This study assessed (i) the added variance explained by bother/distress to the diagnostic accuracy of PE and (ii) determined its overall contribution to a PE diagnosis.
The 3 diagnostic criteria for PE were assessed in 2,589 men (mean age = 38.2 years, SD = 13.5) in order to determine the contribution of each factor to a dysfunctional diagnosis. A series of regression and discriminant analyses were used to assess the value of bother/distress in explaining ejaculatory control and in predicting accuracy of PE group status. Commonality analysis was used to determine the relative contribution of each of these factors to the diagnosis of PE.
The major outcome was the quantified contribution of "bother/distress" to a PE diagnosis.
Bother/distress accounted for about 3-4% of the variation in ejaculatory control and added only minimally to the prediction accuracy of PE group status (no, probable, definite PE). Commonality analysis indicated that bother/distress comprised about 3.6% of the unique explained variation in the PE diagnosis, compared with ejaculatory control and EL which contributed 54.5% and 26.7%, respectively. Common variance among factors contributed the remaining 15.5% to the PE diagnosis.
Bother/distress contributes least to the determination of a PE diagnosis. Its contribution is largely redundant with the unique and combined contributions of ejaculatory control and EL.
Using a well-powered and multivariate analysis, this study parsed out the relative contributions of the 3 diagnostic criteria to a PE diagnosis. The study is limited by its use of estimated EL, a single item assessment of bother/distress, and the lack of differentiation of PE subtypes, lifelong and acquired.
Bother/distress contributes minimally to the PE diagnosis, yet its assessment may be key to understanding the experiences of the patient/couple and to developing an effective treatment strategy.

与早泄（PE）的另外两个诊断标准，即射精控制和射精潜伏期（EL）相比，困扰/苦恼在早泄诊断中的作用受到的研究极少。
本研究评估了（i）困扰/苦恼对早泄诊断准确性所解释的额外方差，以及（ii）确定其对早泄诊断的总体贡献。
对2589名男性（平均年龄 = 38.2岁，标准差 = 13.5）评估了早泄的3个诊断标准，以确定每个因素对功能障碍诊断的贡献。使用一系列回归和判别分析来评估困扰/苦恼在解释射精控制和预测早泄组状态准确性方面的价值。共同性分析用于确定这些因素各自对早泄诊断的相对贡献。
主要结果是“困扰/苦恼”对早泄诊断的量化贡献。
困扰/苦恼占射精控制变异的约3 - 4%，对早泄组状态（无、可能、明确早泄）的预测准确性仅略有增加。共同性分析表明，困扰/苦恼约占早泄诊断中独特解释变异的3.6%，相比之下，射精控制和EL分别贡献了54.5%和26.7%。因素之间的共同方差对早泄诊断贡献了其余的15.5%。
困扰/苦恼对早泄诊断的贡献最小。其贡献在很大程度上与射精控制和EL的独特及综合贡献冗余。
本研究采用了有力的多变量分析，剖析了3个诊断标准对早泄诊断的相对贡献。该研究的局限性在于使用了估计的EL、对困扰/苦恼的单项评估，以及缺乏对终身性和获得性早泄亚型的区分。
困扰/苦恼对早泄诊断的贡献极小，但其评估可能是理解患者/夫妻经历以及制定有效治疗策略的关键。罗兰·D·L、麦克纳布尼·S·M、赫韦西·K。困扰/苦恼对早泄诊断有贡献吗？《性医学》2022；10：100548。
