RESUMO
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 (MoCA). 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.
RESUMO
Objective:To investigate the intrarater and interrater reliability of Chinese version of Weekly Calendar Planning Activity (WCPA-C) as evaluating the executive function in college students. Methods:From August to November, 2019, 55 college students aged 18 to 30 participated in this study. One rater evaluated all the subjects with WCPA-C and retested two weeks later. Two raters evaluated 31 of the subjects with WCPA-C. The intraclass correlation coefficient (ICC) was calculated for intrarater and interrater. Results:Two cases dropped out. The ICCs of the indexes were 0.45 to 0.89 for intrarater excepted Total Errors, and they were better from the second assessment than the first time. The ICC for interrater was 0.84 to 1.00. Conclusion:WCPA-C is well interrater reliable for the healthy college students in China, however, there may be learning effect as interval of two weeks.
