Behavioural Activation (BA) and Acceptance and Commitment Therapy (ACT) aim to reduce the inflexible avoidance of painful thoughts, feelings and memories and to encourage involvement in relevant activities, objectives which are clearly relevant to the situation of cancer survivors with emotional problems. With a view to evaluating and comparing the efficacy of both therapies, applied on a group basis, a randomized controlled trial was developed. Cancer survivors (age 18-65 years) with anxiety and/or depression were assigned at random to two experimental groups (BA; ACT) and a waiting list control group (WL). Of the 66 cancer survivors randomized to trial (intention-to-treat sample), 46 participants (M = 51.49; SD = 6.88) completed the intervention (BA, n = 17; ACT, n = 12; WL, n = 17) (per-protocol sample). The emotional state, experiential avoidance and behavioural activation of the participants was evaluated in the pre- and post-treatment and in a 3-month follow-up using standardized instruments. Both treatment groups showed statistically significant changes, indicating an improvement in all the result variables in the post-treatment and follow-up as compared to the pre-treatment. BA showed better results than ACT regarding impact on anxiety and activation. This greater efficacy may have been due to factors such as the emphasis placed in BA on behavioural activation and the central role played in it by functional analysis. The key role played by experiential avoidance and behavioral activation in the maintenance and treatment of emotional problems in cancer survivors is discussed.

行为激活、接受和承诺疗法治疗癌症幸存者的焦虑和抑郁：一项随机临床试验。

行为激活 (BA) 和接受与承诺疗法 (ACT) 旨在减少对痛苦的想法、感受和记忆的僵化回避，并鼓励参与相关活动，这些目标与有情绪问题的癌症幸存者的情况明显相关。为了评估和比较两种疗法的疗效，以组为基础，开发了一项随机对照试验。患有焦虑症和/或抑郁症的癌症幸存者（18-65 岁）被随机分配到两个实验组（BA；ACT）和一个等待名单对照组（WL）。在随机接受试验的 66 名癌症幸存者（意向治疗样本）中，46 名参与者（M = 51.49；SD = 6.88）完成了干预（BA，n = 17；ACT，n = 12；WL，n = 17） （每个协议样本）。情绪状态，在治疗前和治疗后以及在 3 个月的随访中使用标准化仪器评估参与者的体验性回避和行为激活。两个治疗组均显示出统计学上的显着变化，表明与治疗前相比，治疗后和随访中的所有结果变量都有所改善。在对焦虑和激活的影响方面，BA 显示出比 ACT 更好的结果。这种更大的功效可能是由于诸如 BA 中强调行为激活以及功能分析在其中发挥的核心作用等因素。讨论了经验性回避和行为激活在维持和治疗癌症幸存者情绪问题中的关键作用。原始数据可在线获取（http://dx.doi.org/10.17632/m7w688khs8.1）。
