周历活动规划中文版在社区中老年人执行功能评测中的信度和效度

Reliability and Validity of the Chinese Version of Weekly Calendar Planning Activity for Executive Function Assessment in Community-dwelling Middle-aged and Elderly Adults

目的探究周历活动规划中文版(WCPA-C)在社区中老年人执行功能评测中的重测信度和区分效度。方法 2020年7月至8月,共招募55例41~89岁的社区中老年人。使用WCPA-C对其中30例受试者进行3次评估,首次评估使用版本A,在间隔2周和4周后分别使用版本B和版本A进行重测,计算3次评估间的组内相关系数(ICC值)。根据蒙特利尔认知评估量表(Mo CA)得分将受试者分为轻度认知功能障碍(MCI)组(n=37)和认知正常(NC)组(n=18),比较两组WCPA-C结果。结果共26例受试者完成3次评估,4例在末次评估时失访。除计划时间外,第1、2次评估间的ICC值为0.43~0.78,第2、3次评估间,ICC值为0.50~0.80。MCI组与NC组比较,除总时间和计划时间外(Z <1.641,P> 0.05),其余指标均有显著性差异(Z> 1.288, P <0.05)。结论 WCPA-C在我国社区中老年人中具有满意的重测信度和区分效度。

Objective To examine the reliability and validity of a performance-based executive function assessment,the Chinese Version of Weekly Calendar Planning Activity(WCPA-C),in community-dwelling middle-aged and elderly adults.Methods From July to August,2020,55 community-dwelling adults aged 41 to 89 years participated in this study.A total of 30 participants were evaluated with the WCPA-C version A.After two weeks and four weeks,they were retested with version B and version A,respectively.The intraclass correlation coefficient(ICC)was calculated.All the participants were divided into the mild cognitive impairment(MCI)group(n=37)and normal cognition(NC)group(n=18)according to the scores of the Montreal Cognitive Assessment(Mo CA).The results of WCPA-C between two groups were compared.Results There were four participants lost,and 26 participants completed all three tests.Except the planning time,the ICCs were 0.43~0.78 between the first and the second tests,and were 0.50~0.80 between the second and the third tests.WCPA-C results were significant different between two groups(Z>1.288,P<0.05),except the total time and the planning time(Z<1.641,P>0.05).Conclusion WCPA-C demonstrats satisfactory test-retest reliability and discriminative validity in community-dwelling middle-aged and elderly adults.
