目的检验步履式追踪测验(S-TMT)在社区老年人中的信度和效度。参与者包括1224名居住在社区的日本老年女性，年龄在65-81岁之间，没有功能性残疾、痴呆症、抑郁症、帕金森氏症或认知和视觉障碍。S-TMT测量了踩在1米(2)垫上的一系列数字(1-16)所需的时间。参与者被指示以尽可能快和准确的速度迈出步伐。运动功能评定采用步行速度和伸膝力量测验，认知功能评定采用符号数字替代任务测验、言语和逻辑记忆测验、TMT-A和-B。结果经过6个月的重测信度检验，S-TMT的组内相关系数为0.82(95%可信区间为0.68~0.90)。调整后的多元回归模型显示，运动功能与步行速度显著相关，认知功能与SDST、TMT-A和TMT-B显著相关(P<；0.001)。结论S-TMT是一种可靠的双任务测验，包括运动功能的移动和认知功能的视觉依赖执行功能。Geriatr Gerontol Int 2020；中心点中心点：中心点中心点-中心点中心点。
Aim This study aimed to examine the reliability and construct validity of the Stepping Trail Making Test (S-TMT) in community-dwelling older adults.Methods This study comprised a cross-sectional study based on a population sample. Participants comprised 1224 community-dwelling older Japanese women aged 65-81 years without functional disability, dementia, depression, Parkinson's disease, or cognitive and visual impairments. The S-TMT measured the time taken to step on a sequence of numbers (1-16) positioned on a mat (1 m(2)). Participants were instructed to step as quickly and accurately as possible. Motor functions were assessed by walking speed and knee extensor strength tests, while cognitive functions were assessed by the Symbol Digit Substitution Task (SDST) test, verbal and logical memory test, and TMT-A and -B.Results As a result of test-retest reliability over 6 months, the intraclass correlation coefficients of the S-TMT was 0.82 (95% confidence interval, 0.68-0.90). An adjusted multiple regression model indicated that the S-TMT was significantly associated with walking speed for motor function, and associated with the SDST, TMT-A and TMT-B for cognitive functions (P < 0.001).Conclusions These results suggest that the S-TMT is a reliable dual-task test comprising mobility for motor function and a visual-dependent execution function for cognitive function in older women.
