OBJECTIVE This study examined variability in response to a couple and relationship education program for Black coparenting couples using group-based trajectory modeling. We identified groups of couples with different relationship satisfaction trajectories across a 2-year period following preintervention assessment. METHOD Black couples with a preadolescent child were randomized to the Protecting Strong African American Families intervention (N = 170) or a control condition (N = 174) and reported on their relationship satisfaction preintervention and approximately 9, 17, and 25 months later. RESULTS Results indicated two trajectory groups among men and women receiving the intervention, comprising a large group consistently high in relationship satisfaction over time and a smaller group with moderate, stable satisfaction over time. In the control condition, there was also a large group of men and women who remained consistently high in satisfaction, but the smaller group with initially moderate satisfaction experienced decreased satisfaction over time. Trajectories among men and women in the moderate groups differed by treatment condition, reflecting nonsignificant change (i.e., stable satisfaction) for those receiving intervention and significant decline for controls. Trajectories among women in the high group also differed by treatment condition, reflecting better functioning among women receiving intervention. CONCLUSIONS Results indicated many benefits of intervention, most notably the stabilization of satisfaction among couples beginning with moderate satisfaction (who experienced declining satisfaction in the control condition). Similar examination of within-sample variability in response to other couple and relationship education programs may enhance understanding of specific treatment effects and guide identification of those most likely to benefit from relationship intervention.

预防性关系干预后农村黑人夫妇关系满意度的不同轨迹。


目的 本研究使用基于群体的轨迹模型研究了黑人共同养育夫妇对夫妻和关系教育计划的反应差异。在干预前评估后的两年内，我们确定了几组具有不同关系满意度轨迹的夫妇。方法 将有青春期前儿童的黑人夫妇随机分配到保护强大的非裔美国人家庭干预组 (N = 170) 或对照条件组 (N = 174)，并报告他们在干预前以及大约 9、17 和 25 个月后的关系满意度。结果 结果表明，接受干预的男性和女性有两个轨迹组，其中一大组随着时间的推移关系满意度始终保持较高水平，另一组较小的组随着时间的推移具有中等、稳定的满意度。在对照条件下，还有一大群男性和女性始终保持较高的满意度，但最初具有中等满意度的较小群体随着时间的推移，满意度逐渐下降。中等组中男性和女性的轨迹因治疗条件而异，反映出接受干预的患者无显着变化（即稳定的满意度），而对照组则显着下降。高组女性的轨迹也因治疗条件而异，反映出接受干预的女性功能更好。结论 结果表明干预有很多好处，最显着的是从中等满意度开始的夫妇满意度的稳定（在控制条件下满意度下降）。 对其他夫妻和关系教育计划的样本内变异性的类似检查可能会增强对特定治疗效果的理解，并指导识别那些最有可能从关系干预中受益的人。 （PsycInfo 数据库记录 (c) 2024 APA，保留所有权利）。
