性功能障碍与抑郁症和焦虑症有关，但这些关系的性质仍不清楚。这项研究通过比较（a）一个包含因果关系的模型，（b）一个用所有疾病之间共有的潜在因素（或潜在责任）解释随时间变化的模型，以及（c）一个将性功能障碍概念化为与抑郁症和焦虑症无关的模型，研究了这些疾病症状随时间的关系。参与者 (n = 1,012) 在每周或每月的六个时间点完成了性功能障碍、抑郁症和焦虑症的在线自我报告测量。根据相隔 4 周收集的数据，模型 1 和 2 为男性和女性提供了同等的最佳拟合度，但模型 1 中没有明显的因果关系。使用相隔 1 周和 6 个月收集的数据进行的后续分析发现，模型 2 为女性提供了稳健的拟合度，但由于样本量不足，这些数据并未针对男性进行检验。这些结果与随着时间的推移推动这些疾病发生变化的内化精神病理学的共同潜在责任相一致，这为经验驱动的疾病分类学和跨诊断治疗的未来研究提供了明确的方向。
Sexual dysfunctions are related to depressive and anxiety disorders, but the nature of these relationships remains unclear. This study examined the relationship among symptoms of these disorders over time by comparing (a) a model that included causal relationships, (b) a model that accounted for change over time with a shared underlying factor (or latent liability) among all the disorders, and (c) a model that conceptualized sexual dysfunctions as unrelated to depressive and anxiety disorders over time. Participants (n = 1,012) completed online self-report measures of sexual dysfunctions and depressive and anxiety disorders across six time points at either weekly or monthly intervals. Models 1 and 2 provided equal best fit for men and women based on data collected four weeks apart, but there were no evident causal relationships in Model 1. Subsequent analyses using data collected one week and six months apart found Model 2 provided robust fit for women, but these data were not examined for men due to inadequate sample sizes. The results are consistent with a shared latent liability of internalizing psychopathology driving the change in these disorders over time, which provides a clear direction for an empirically driven nosology and for future research into transdiagnostic treatments.
