The symptoms of antisocial personality disorder (ASPD) and broader personality trait domains such as negative emotionality (NEM) may prove detrimental for marital quality. Previous research with European Americans has found that ASPD negatively predicts couple functioning, even when controlling for NEM. The current study extends previous work by testing whether ASPD (as well as a history of early conduct disorder) and NEM are related to marital quality trajectories in a sample of 450 Mexican-origin couples followed over 9 years. Consistent with other studies, there was a slight average decline in relationship quality over the course of the study along with differences between couples in the initial level of relationship quality and rate of change. Results indicated that NEM was a stronger correlate of initial levels of marital quality than ASPD. Findings underscore the relevance of NEM as a personality trait domain relevant for relationships.

墨西哥-原籍夫妇的反社会特征，负面情绪和关系质量的轨迹。

反社会人格障碍（ASPD）的症状和更广泛的人格特质领域，例如负面情绪（NEM），可能对婚姻质量有害。以前与欧美人进行的研究发现，即使控制NEM，ASPD也会负面预测夫妻功能。当前的研究通过测试ASPD（以及早期行为障碍的病史）和NEM是否与婚姻质量轨迹有关，该研究来自于9年的450名墨西哥裔夫妇。与其他研究一致，在研究过程中，关系质量略有平均下降，并且夫妻之间的关系质量和变化率的初始水平也存在差异。结果表明，与ASPD相比，NEM与婚姻质量初始水平的相关性更强。
