This study evaluated the effectiveness of mindfulness-based cognitive therapy (MBCT) for individuals with a diagnosis of cancer.
Participants (N = 115) diagnosed with cancer, across site and stage, were randomly allocated to either the treatment or the wait-list condition. Treatment was conducted at 1 site, by a single therapist, and involved participation in 8 weekly 2-hr sessions that focused on mindfulness. Participants meditated for up to 1 hr daily and attended an additional full-day session during the course. Participants were assessed before treatment and 10 weeks later; this second assessment occurred immediately after completion of the program for the treatment condition. The treatment condition was also assessed at 3 months postintervention. All postinitial assessments were completed by assessors who were blind to treatment allocation.
There were large and significant improvements in mindfulness (effect size [ES] = 0.55), depression (ES = 0.83), anxiety (ES = 0.59), and distress (ES = 0.53) as well as a trend for quality of life (ES = 0.30) for MBCT participants compared to those who had not received the training. The wait-list group was assessed before and after receiving the intervention and demonstrated similar change.
These improvements represent clinically meaningful change and provide evidence for the provision of MBCT within oncology settings.
本研究评估了正念认知疗法（MBCT）对癌症患者的有效性。
参与者（N=115）被诊断患有癌症，无论其所在地点和阶段如何，均被随机分配到治疗组或候补名单组。治疗在一个地点进行，由一名治疗师进行，包括参加 8 次每周 2 小时的正念集中治疗。参与者每天冥想长达 1 小时，并在课程期间参加额外的全天课程。参与者在治疗前和 10 周后进行评估；对于治疗组，第二次评估在完成治疗方案后立即进行。治疗组还在干预后 3 个月进行评估。所有初始评估后评估均由不了解治疗分配的评估者进行。
与未接受培训的参与者相比，MBCT 参与者的正念（效应大小[ES]=0.55）、抑郁（ES=0.83）、焦虑（ES=0.59）和痛苦（ES=0.53）显著提高，生活质量（ES=0.30）也有提高趋势。候补名单组在接受干预前后进行了评估，表现出类似的变化。
这些改善代表了具有临床意义的变化，并为在肿瘤学环境中提供 MBCT 提供了证据。
