In this study, we examined mediators of a brief couples intervention. Intimate safety, acceptance, and activation were examined in 2 roles: their contribution to marital satisfaction gains in the first 2 weeks after treatment (contemporaneous effects), and how early changes in the mediators influenced longer term changes in marital satisfaction over 2 years of follow-up (lagged effects). Married couples (N = 215) were randomized to either an intervention group or a wait-list control group and followed for 2 years. Latent change-score models were used to examine contemporaneous and time-lagged mediation. A booster intervention in the 2nd year was used for a replication study. Changes in intimate safety and acceptance were uniquely associated with contemporaneous treatment effects on relationship satisfaction in Year 1, but only acceptance was uniquely associated with contemporaneous effects in Year 2. With respect to lagged effects, early changes in acceptance partially mediated later changes in marital satisfaction in Year 1, whereas the same effect for intimate safety was marginally significant. These lagged paths were moderate in size and indirect effects were small. No lagged effects were significant in Year 2. Change in activation was not significant as either a contemporaneous or a lagged predictor of change in relationship satisfaction. We found moderate support for acceptance and more limited support for intimate safety as mediators of short- and long-term treatment response, suggesting that these processes play an important role in sustaining marital health.
在本研究中，我们考察了一种简短的夫妻干预措施的中介因素。从两个方面考察亲密安全感、接纳度和积极性：它们对治疗后前两周婚姻满意度提升的贡献（同期效应），以及中介因素的早期变化如何在两年的随访中影响婚姻满意度的长期变化（滞后效应）。已婚夫妇（N = 215）被随机分为干预组或等待名单对照组，并随访两年。使用潜在变化分数模型来考察同期和时间滞后的中介作用。在第二年进行了强化干预以进行重复研究。亲密安全感和接纳度的变化与第1年关系满意度的同期治疗效果有独特关联，但只有接纳度与第2年的同期效果有独特关联。关于滞后效应，接纳度的早期变化在第1年部分中介了婚姻满意度的后期变化，而亲密安全感的相同效应则微弱显著。这些滞后路径的规模适中，间接效应较小。在第2年没有显著的滞后效应。积极性的变化作为关系满意度变化的同期或滞后预测指标均不显著。我们发现，作为短期和长期治疗反应的中介因素，接纳度得到了适度支持，而亲密安全感得到的支持更为有限，这表明这些过程在维持婚姻健康方面发挥着重要作用。
