Dementias are highly prevalent among Chinese elders. This study examined the effectiveness of a modified group cognitive behavioral therapy (CBT) on dementia worry among Chinese older adults.
Eighty-two older adults recruited from four elder group homes were randomly assigned to either intervention or control group. The intervention group (n= 44) received eight weekly 60-minute face-to-face CBT, while the control group (n=38) received treatment-as-usual.
Outcomes indicated that the modified group CBT has significantly reduced dementia worry and culturally biased beliefs about dementia (p<.001). Study findings supported both statistically and clinically significant effect of modified group CBT on dementia worry [g=-1.52, 95% CI (-2.01, -1.03)] and biased beliefs about dementia [g=-.95, 95% CI (-1.40, -.49)].
The culturally adapted CBT is promising in alleviating worries and anxiety over dementia among Chinese older adults. Future research needs to include larger samples and participants from different regions to replicate findings.
痴呆在华裔老年人中发病率极高。本研究旨在检验改良团体认知行为疗法（CBT）对中国老年人痴呆担忧的效果。
从 4 个老年群体之家招募了 82 名老年人，他们被随机分配到干预组（n=44）或对照组（n=38）。干预组接受每周 8 次、每次 60 分钟的面对面 CBT，而对照组则接受常规治疗。
结果表明，改良团体 CBT 显著降低了痴呆担忧和对痴呆的文化偏见信念（p<.001）。研究结果支持改良团体 CBT 对痴呆担忧[g=-1.52，95%置信区间（-2.01，-1.03）]和对痴呆的偏见信念[g=-.95，95%置信区间（-1.40，-.49）]具有统计学和临床意义上的显著效果。
文化适应性 CBT 有望减轻华裔老年人对痴呆的担忧和焦虑。未来的研究需要纳入更大的样本和来自不同地区的参与者，以复制研究结果。
