Following brain injury, the risk of depression increases. There are few studies of non-pharmacological interventions for this problem. Behavioural Activation (BA) could help because it has been demonstrated to be as effective as cognitive-behaviour therapy but is less cognitively demanding and more suitable for people with brain impairment. The current study evaluated BA using a multiple-baseline design across behaviours with replication. Three male participants with clinically significant depressive symptoms (two with traumatic brain injury aged 26 and 46, one who experienced strokes in infancy, aged 26) engaged in a 10-14-week trial of BA focusing on three activity domains: physical, social and functional activities. Participants completed an online form three times a day which recorded activity participation and responses to a single-item mood scale. There was little evidence in support of BA for increasing participation. There was also a lack of change in average mood, but some positive effects were found on measures of depression symptoms and quality of life in these participants. Various factors affected participation which might have been mitigated by extended treatment contact, greater use of prompts or electronic aids or the addition of other therapy modes.

行为激活疗法可提高成人脑损伤后抑郁症的参与度：单例实验设计研究

脑损伤后，患抑郁症的风险增加。针对这个问题的非药物干预研究很少。行为激活 (BA) 可能会有所帮助，因为它已被证明与认知行为疗法一样有效，但对认知的要求较低，更适合脑损伤患者。当前的研究使用跨行为的多基线设计与复制评估了 BA。三名有临床显着抑郁症状的男性参与者（两名分别为 26 岁和 46 岁患有创伤性脑损伤，一名在婴儿期中风，26 岁）参与了为期 10-14 周的 BA 试验，重点关注三个活动领域：身体、社交和功能性活动。参与者每天完成三次在线表格，记录活动参与和对单项情绪量表的反应。几乎没有证据支持 BA 增加参与度。平均情绪也没有变化，但在这些参与者的抑郁症状和生活质量的测量中发现了一些积极的影响。各种影响参与的因素可能会通过延长治疗接触、更多地使用提示或电子辅助工具或添加其他治疗模式来减轻。
