Personality disorders (PDs) are inherently associated with deficits in relating to other people. Previous research has shown consistent negative associations between categorical PD symptoms and relationship satisfaction. The present studies extend on these findings by examining the role of maladaptive traits in a number of ways. Self- and partner-reported maladaptive traits of both partners are included. Moreover, the present studies add a couple-centered approach by investigating the effects of actual similarity, perceptual similarity, and perceptual accuracy of the maladaptive trait profile on relationship satisfaction. PDs are conceptualized using 2 dimensional maladaptive trait models, that is, the Dimensional Assessment of Personality Pathology-Basic Questionnaire in Study 1 and the Personality Inventory for DSM-5 in Study 2. A total of 167 heterosexual couples participated in Study 1 and 52 heterosexual couples in Study 2. The actor-partner interdependence model was used to examine the associations between traits and relationship satisfaction, whereas the coefficient of profile agreement was used for the couple-centered analyses. Overall, results showed that the presence of maladaptive traits within romantic relationships has a detrimental effect on relationship satisfaction. Self-ratings on maladaptive traits, how we perceive our partners, and how we are perceived by our partners on maladaptive traits make significant contributions to our relationship (dis)satisfaction. Among the maladaptive traits, negative affect and detachment were most consistently negatively associated with relationship satisfaction. The couple-centered perspective showed less explanatory value but nontrivial associations between perceptual similarity and relationship satisfaction were found in Study 2. (PsycINFO Database Record
人格障碍（PD）与与他人交往的缺陷密切相关。以前的研究表明，类别 PD 症状与关系满意度之间存在一致的负面关联。本研究通过多种方式扩展了这些发现，研究了适应不良特征的作用。包括了自我和伴侣报告的双方的适应不良特征。此外，本研究通过研究适应不良特征特征的实际相似性、感知相似性和感知准确性对关系满意度的影响，增加了夫妻为中心的方法。PD 使用二维适应不良特征模型来概念化，即研究 1 中的人格病理评定维度问卷和研究 2 中的 DSM-5 人格量表。共有 167 对异性恋夫妇参加了研究 1，52 对异性恋夫妇参加了研究 2。演员-伴侣相互依存模型用于检验特征与关系满意度之间的关联，而特征一致系数用于夫妻为中心的分析。总的来说，结果表明，浪漫关系中存在适应不良特征会对关系满意度产生不利影响。适应不良特征的自我评估、我们如何感知伴侣以及我们被伴侣感知到的适应不良特征对我们的关系（不）满意度有重要贡献。在适应不良特征中，负性情绪和疏离与关系满意度的负相关最一致。夫妻为中心的观点显示出较小的解释价值，但在研究 2 中发现感知相似性与关系满意度之间存在重要关联。
