This study examined the effects of Behavioral Activation (BA) treatment on depressive symptoms and quality of life among older adult patients in a geriatric psychiatry facility. There were 50 participants with mild to moderate cognitive impairment, each being 65 years of age or older. A 2 (between)×3 (time of measurement) design was used in this study comparing control (treatment-as-usual) and experimental (BA) conditions at pre-, mid-, and posttreatment. BA consisted of eight 30- to 60-minute sessions across 4 weeks. Intent-to-treat analyses indicated a significant Group×Time interaction on depressive symptoms, with this effect remaining when only completer data were included. Further analyses indicated that this effect was due to significant change early in treatment in both the full and completer samples. There was no evidence of a significant effect on the quality-of-life measure. Cognitive status was not related to change in depressive symptoms, suggesting that BA may be useful across a range of older adults.
本研究旨在探讨行为激活（BA）疗法对老年精神病院轻度至中度认知障碍老年患者的抑郁症状和生活质量的影响。共有 50 名参与者，年龄均在 65 岁或以上，认知功能轻度至中度受损。本研究采用 2（组间）×3（测量时间）设计，比较了对照组（常规治疗）和实验组（BA）在治疗前、中期和治疗后的情况。BA 包括 4 周内 8 次 30-60 分钟的治疗。意向治疗分析表明，抑郁症状的组间×时间交互作用显著，仅包括完成者数据时仍存在此效应。进一步的分析表明，这种效果是由于在治疗的早期，无论是在完整样本还是完成者样本中，都有显著的变化。在生活质量测量方面，没有证据表明有显著影响。认知状态与抑郁症状的变化无关，这表明 BA 可能对一系列老年人都有用。
