To examine the role of psychological flexibility as a potential mediator in the relationship between involvement in a guided self-help intervention, Self-Help Plus, and psychological distress in a sample of South Sudanese refugee women living in northern Uganda.
We conducted secondary analysis of data from a cluster randomized controlled trial conducted in 2018. We used multilevel mediation modeling to explore the relationship of psychological flexibility, as measured by the Acceptance and Action Questionnaire (AAQ-II), as a mediating factor in the relationship between Self-Help Plus involvement and general psychological distress as measured by the Kessler Psychological Distress Scale-6 (K6).
We found strong multilevel mediation of decreased K6 scores in the treatment group by AAQ-II scores (multilevel b = -3.28). A more pronounced mediation effect was discovered immediately post intervention (b = -1.09) compared to 3-month follow-up (b = -0.84). This is in line with the current literature that demonstrates the role of psychological flexibility as a primary mechanism of change in ACT-based interventions.
Psychological flexibility is a contributing component in the theory of change for this ACT-based intervention. Identifying the core components of interventions allows for more effective adaptation and implementation of relevant services, especially in low-resource contexts.

在乌干达北部生活的南苏丹难民女性样本中，检验心理灵活性作为一个潜在中介，在参与指导自助干预（Self-Help Plus）与心理困扰之间的关系中的作用。
我们对 2018 年进行的一项群组随机对照试验的数据进行了二次分析。我们使用多层次中介模型来探讨心理灵活性（通过接受与行动问卷（AAQ-II）来衡量）作为中介因素，在 Self-Help Plus 参与和由 Kessler 心理困扰量表-6（K6）衡量的一般心理困扰之间的关系。
我们发现，治疗组的 K6 评分通过 AAQ-II 评分呈现出很强的多层次中介作用（多层次 b = -3.28）。与 3 个月随访（b = -0.84）相比，在干预后立即发现了更明显的中介效应（b = -1.09）。这与当前的文献一致，即表明心理灵活性是基于 ACT 的干预中的主要变化机制。
心理灵活性是基于 ACT 的干预的变化理论中的一个组成部分。确定干预的核心组成部分可以使相关服务的更有效适应和实施，特别是在资源匮乏的环境中。
