Personality disorders (PDs) are significantly, negatively related to marital satisfaction. We examine how maladaptive personality is related to change in marital satisfaction over time utilizing data from the St. Louis Personality and Aging Network (SPAN), a longitudinal, community-based study of personality and health in older adults. Participants were assessed at baseline for PD (self-report, informant-report, and structured interview); self- and spouse-reported relationship satisfaction assessed at baseline and five follow-ups was analyzed with latent growth curve modeling. Higher levels of PD at baseline were associated with lower self and spouse relationship satisfaction at baseline. On average, satisfaction did not change significantly over the study period, but there was significant individual variability. Higher levels of schizoid PD were protective of declines in partner's perception of satisfaction. Findings suggest that partners in long-term married unions may have adapted to the presence of their own or their spouse's level of personality pathology.

人格障碍对长期已婚夫妇关系满意度的纵向变化的影响。

人格障碍（PDs）与婚姻满意度显着负相关。我们利用来自圣路易斯性格和老龄化网络（SPAN）的数据，研究适应不良的人格与婚姻满意度随时间的变化如何相关，这是一项针对老年人的性格和健康状况的纵向社区研究。在基线时评估参与者的PD（自我报告，知情者报告和结构化访谈）；自我评估和配偶报告的关系满意度在基线时进行了评估，并通过潜伏增长曲线模型对五次随访进行了分析。基线时较高的PD水平与基线时较低的自我和配偶关系满意度相关。平均而言，在研究期间满意度没有显着变化，但是个体差异很大。较高的精神分裂症PD可保护伴侣的满意度下降。研究结果表明，长期已婚工会中的伴侣可能已经适应了自己或配偶的个性病态水平。
