摘要

背景:尽管有证据表明,以认知行为疗法(CBT)为基础的团体干预可以改善接受乳腺癌(BC)治疗的妇女的生活质量(QoL),但人们对这些效果的中介和调节因素知之甚少。我们研究了 a) 认知行为压力管理(CBSM)干预后,受益发现对 QoL 变化的中介作用,以及 b) 这种中介作用是否因 BC 术后第一年的基线乐观程度而异:我们使用了之前一项 CBSM 试验的数据,试验对象是 240 名 0-3 期 BC 女性患者,她们在基线(手术后 2-10 周)、随机分配后 6 个月和 12 个月完成了受益发现量表(受益发现量表,BFS)、QoL(癌症治疗功能评估,FACT-G)和乐观情绪(生活取向测试-修订版)的测量。我们使用潜在增长曲线模型评估了与 CBSM 相关的变化以及中介和调节效应:结果:我们发现 CBSM 增加了受益发现(b = 2.65,p 结论:CBSM 干预改善了患者的情绪质量:CBSM干预改善了乳腺癌治疗第一年的情绪QoL,提高了特质乐观度较低的妇女的获益发现率,这表明在这一紧张时期,获益发现率的提高最有可能使这些妇女受益。

Functions of Resiliency Traits and Processes in Differential Effects of CBSM on Quality of Life in Breast Cancer Survivors: A Moderated Mediation Model.

Background: Although there is evidence that cognitive behavioral therapy (CBT)-based group interventions can improve quality of life (QoL) in women undergoing treatment for breast cancer (BC) little is known about factors that mediate and moderate these effects. We examined a) the mediating role of benefit finding on QoL changes after a Cognitive Behavioral Stress Management (CBSM) intervention, and b) whether this mediation effect differed based on baseline optimism in the first year following surgery for BC.

Methods: We used data from a prior CBSM trial in 240 women with stage 0-3 BC who completed measures of benefit finding (Benefit Finding Scale, BFS), QoL (Functional Assessment of Cancer Treatment, FACT-G), and optimism (Life Orientation Test-Revised) at baseline (2 - 10 weeks post-surgery), 6-months and 12-months after randomization. CBSM-related changes and mediation and moderation effects were assessed using latent growth curve models.

Results: We found CBSM increased benefit finding (b = 2.65, p < 0.01), emotional (b = 0.53, p < 0.01), and functional QoL (b = 0.71, p < 0.05) over time. CBSM-related changes in emotional QoL were mediated by increased benefit finding (indirect effect = 0.68, 95% bootstrapped CI: 0.17, 1.56) but only among participants with low to moderate optimism at baseline.

Conclusion: CBSM intervention improved emotional QoL over the first year of breast cancer treatment by increasing benefit finding among women who reported low trait optimism suggesting those who will most likely benefit from improving benefit finding during this stressful period.

期刊介绍: The International Journal of Behavioral Medicine (IJBM) is the official scientific journal of the International Society for Behavioral Medicine (ISBM). IJBM seeks to present the best theoretically-driven, evidence-based work in the field of behavioral medicine from around the globe. IJBM embraces multiple theoretical perspectives, research methodologies, groups of interest, and levels of analysis. The journal is interested in research across the broad spectrum of behavioral medicine, including health-behavior relationships, the prevention of illness and the promotion of health, the effects of illness on the self and others, the effectiveness of novel interventions, identification of biobehavioral mechanisms, and the influence of social factors on health. We welcome experimental, non-experimental, quantitative, qualitative, and mixed-methods studies as well as implementation and dissemination research, integrative reviews, and meta-analyses.
