Provoked vestibulodynia (PVD) is a chronic, recurrent vulvo-vaginal pain condition affecting 12% of the general population, and is associated with sexual dysfunction, psychological distress, and reduced quality of life. There is growing interest in the role of interpersonal variables in PVD, which have been widely neglected. In a sample of 175 couples, the present study examined the mediating roles of partner and participant catastrophizing and self-efficacy in the association between solicitous partner responses and pain intensity, and that of dyadic adjustment in the association between solicitous and negative partner responses and sexual satisfaction. Couples completed measures of partner responses, catastrophizing, self-efficacy, dyadic adjustment, and depression. Women also completed measures of pain, sexual satisfaction, and sexual function. Controlling for depression and solicitousness perceived by the other member of the couple, catastrophizing and self-efficacy partially mediated the association between higher solicitous responses and higher pain during intercourse, accounting for 26 and 25% of the variance in this association for participant and partner-perceived responses, respectively. For both participant and partners, only pain catastrophizing was a unique mediator. Controlling for depression, sexual function and partner-perceived responses, dyadic adjustment partially mediated the association between higher participant-perceived solicitous responses and higher sexual satisfaction, and between higher participant-perceived negative responses and lower sexual satisfaction, accounting for 26% of the variance in each association. The current findings suggest that catastrophizing and dyadic adjustment may constitute a route by which partner responses exacerbate pain and increase or decrease sexual satisfaction in PVD couples.
诱发性阴道痉挛（PVD）是一种慢性、复发性的外阴阴道疼痛疾病，影响 12%的普通人群，与性功能障碍、心理困扰和生活质量下降有关。人们对 PVD 中人际变量的作用越来越感兴趣，但这些变量一直被广泛忽视。在 175 对夫妇的样本中，本研究检验了伴侣和参与者的灾难化和自我效能感在体贴伴侣反应与疼痛强度之间的关系中的中介作用，以及在体贴和消极伴侣反应与性满意度之间的关系中的夫妻调节的中介作用。夫妻双方完成了伴侣反应、灾难化、自我效能、夫妻调节和抑郁的测量。女性还完成了疼痛、性满意度和性功能的测量。控制了夫妻另一方感知到的抑郁和体贴程度，灾难化和自我效能感部分中介了更高体贴反应与性交时更高疼痛之间的关联，分别占参与者和伴侣感知反应之间这种关联的 26%和 25%。对于参与者和伴侣来说，只有疼痛灾难化是一个独特的中介。控制了抑郁、性功能和伴侣感知的反应，夫妻调节部分中介了参与者感知的更高体贴反应与更高的性满意度之间的关联，以及参与者感知的更高消极反应与较低的性满意度之间的关联，分别占每个关联的 26%。目前的研究结果表明，灾难化和夫妻调节可能是伴侣反应加剧疼痛和增加或降低 PVD 夫妇性满意度的途径。
