目的：正念冥想可以减轻癌症患者的心理困扰。然而，干预效果的机制尚未完全确定。这项研究测试了情绪调节策略作为干预效果的中介，在一个样本的年轻女性接受乳腺癌治疗，一组有心理困扰的风险。我们专注于两个不同的策略，针对的干预-反刍和自我善良-并进一步研究了更广泛的正念结构作为一个潜在的调解人。方法：在50岁或之前诊断为0-III期乳腺癌并完成癌症治疗的女性（n = 71）被随机分配到为期6周的正念干预组或等待名单对照组。在研究入组、干预后和3个月随访时进行评估。结果如下：在单因素分析中，自我友善的增加（CIB [-7.83，-1.93]），沉思的减少（CIB [-5.05，-0.31]）和正念的增加（CIB [-6.58，-0.82]）都介导了干预前后抑郁症状的减少。从干预前到干预后，自我友善的增加也介导了感知压力的减少（CIB [-5.37，-.62]），而自我友善（CIB [-5.67，-.22]）和正念（CIB [-5.51，-.16]）的增加则介导了从干预前到3个月随访的感知压力干预效果。在多中介变量分析中，只有自我友善对干预前后抑郁症状的干预效果起中介作用（CIB [-6.41，-.61]），而自我友善和正念共同对干预前后感知压力的干预效果起中介作用（CIB [-6.77，-.35]）。结论：自我仁慈在减少年轻乳腺癌女性的痛苦方面发挥了一致的作用。这种未充分研究的情绪调节策略的有效性应在其他临床人群中进行评估。
Objective: Mindfulness meditation reduces psychological distress among individuals with cancer. However, mechanisms for intervention effects have not been fully determined. This study tested emotion regulation strategies as mediators of intervention effects in a sample of younger women treated for breast cancer, a group at risk for psychological distress. We focused on two distinct strategies targeted by the intervention-rumination and self-kindness-and further examined the broader construct of mindfulness as a potential mediator. Method: Women (n = 71) with Stage 0-III breast cancer diagnosed at or before age 50 who had completed cancer treatment were randomly assigned to a 6-week mindfulness intervention or wait-list control group. Assessments occurred at study entry, postintervention, and a 3-month follow-up. Results: In single mediator analyses, increases in self-kindness (CIB [-7.83, -1.93]), decreases in rumination (CIB [-5.05, -.31]), and increases in mindfulness (CIB [-6.58, -.82]) each mediated reductions in depressive symptoms from pre- to postintervention. Increases in self-kindness also mediated reductions in perceived stress (CIB [-5.37, -.62]) from pre-to postintervention, and increases in self-kindness (CIB [-5.67, -.22]) and in mindfulness (CIB [-5.51, -.16]) each mediated intervention effects on perceived stress from preintervention to 3-month follow-up. In multiple mediator analysis, only self-kindness mediated intervention effects on depressive symptoms from pre-to postintervention (CIB [-6.41, -.61]), and self-kindness and mindfulness together mediated intervention effects on perceived stress from preintervention to follow-up (CIB [-6.77, -.35]). Conclusions: Self-kindness played a consistent role in reducing distress in younger women with breast cancer. The efficacy of this understudied emotion regulation strategy should be evaluated in other clinical populations.
