목적 : 본 연구는 문화적 차이를 보이는 Upper extremity performance test for elderly (TEMPA)를 한국판으로 수정 및 번역하고 그 타당도 및 신뢰도를 검증하는 것이다. 연구방법 : 연구대상자는 40세이상의 손 기능에 장애가 없는 성인 171명과 손 기능에 장애가 있는 성인 41명 이었다. 내용 타당도와 분별 타당도를 검증하였고, 검사-재검사 신뢰도와 검사자 간 신뢰도를 검증하였다. 결과 : 내용 타당도를 통해 문화적 차이를 보이는 2개의 항목 ('자물쇠 열고 약통 열기', '편지 봉투 작성하고 우표 붙이기')을 수정하였다. 분별 타당도를 통해 TEMPA는 손 기능에 장애가 있는 성인과 없는 성인을 구별할 수 있는 평가 도구임을 확인 하였다 (p<.001). 신뢰도 검증 결과 수행 속도는 급간 내 상관계수(ICC)= .71-.92, 기능 정도는 카파계수 (kappa) = 1.0, 수행 분석은 ICC = 1.0로 중간수준에서 높은 수준의검사-재검사 신뢰도를 보였다. 검사자 간 신뢰도는 실행 속도 ICC = 1.0, 기능 정도 kappa = .79-1.0, 수행 분석 ICC = .94-1.0으로 상당한 수준에서 높은 수준의 신뢰도를 보였다. 결론 : TEMPA는 손 기능의 장애가 있는 성인을 구별해 낼 수 있고, 높은 수준의 신뢰도를 보이는 평가 도구로 임상적 평가 및 근거 기반의 연구에 있어 많이 사용되기를 기대한다.

Objective : This study aimed to verify the validity and reliability of the Upper Extremity Performance Test for the Elderly (TEMPA) by modifying its items to exhibit cultural differences. Methods : This study included 171 healthy adults and older adults and 41 individuals with impaired upper extremity function. Content validity, discriminant validity, test-retest reliability, and inter-rater reliability were analyzed. Results : The following items, exhibiting cultural differences, were modified: "open a lock and take the top off a pillbox" and "write and affix a postage stamp." The discriminant validity results indicated that participants with normal upper extremity function performed better than those with impaired in the upper extremity function (p<.001). The test-retest reliability of the execution speed (intraclass correlation coefficient; ICC) was .71-.94, functional rating (kappa) was 1.0, and task analysis (ICC) was 1.0. The inter-rater reliability of the speed of execution was 1.0, functional rating was .79-1.0, and task analysis was .94-1.0. Conclusion : TEMPA has moderate to high level of reliability and is an assessment tool that can clearly distinguish individuals with upper extremity impairment from those without impairment.

문제 정의
The cultural traits of Koreans must be taken into consideration prior to the implementation of TEMPA in Korea. Therefore, this study aimed to measure the construct validity of TEMPA usage in Korean clinics and modify the assessment tool in accordance with the Korean culture. It also aimed to verify the validity and reliability of the modified TEMPA when used in the Korean clinical setting to evaluate upper extremity function.
This study aimed to verify the validity and reliability of TEMPA. Through the content validity verification process, two items of TEMPA were modified due to cultural differences in experiences and language.
제안 방법
To verify content validity, the content validity index (CVI) calculation method was used (Polit, & Beck, 2006). Discriminant validity was verified by comparing the results of the impaired group and the healthy group. The comparison experiment was conducted separately for the dominant hand and the non-dominant hand.
Functional rating measures how the individual successfully and easily performs the tasks. In the task analysis, the upper extremity performance is measured by five variables: range of movement, strength, control of gross movement, prehension patterns, and fine movement, related to basic neurosensorimotor skills of the upper extremities. Both functional rating and task analysis have a four-point system, ranging from 0 to –3.
Therefore, this study aimed to measure the construct validity of TEMPA usage in Korean clinics and modify the assessment tool in accordance with the Korean culture. It also aimed to verify the validity and reliability of the modified TEMPA when used in the Korean clinical setting to evaluate upper extremity function.
The pillbox opens when the arrows are lined up, but this pillbox is not used in Korea. The participants were not familiar in using this type of pillbox, the arrows were marked with red tape to be more recognizable, and participants were instructed in how to open the pillbox before the test. “Write and affix a postage stamp” was modified for cultural and linguistic reasons.
The tool is used to evaluate an older adult’s performance of nine tasks (four unilateral and five bilateral tasks) selected through task analysis of daily activities.
대상 데이터
A total of 212 individuals, 171 younger and older adults without upper extremity impairment and 41 younger and older adults with upper extremity impairment, were recruited in the study (Table 1, 2). Individuals (1) without neurological and musculoskeletal deficits that affect upper extremity function, (2) without cognitive impairment, and (3) without comprehension difficulties in following instruction during evaluation constituted the healthy group.
데이터처리
0. Among the results of the discriminant validity, the result of the speed of execution was analyzed using an independent t test, and the chi-square test was used to analyze functional rating and task analysis. In the reliability study, ICC was used to analyze the speed of execution and functional rating.
이론/모형
Descriptive statistic was used to analyze demographic information of participants. CVI was a 5-point scale ranging from 1 to 5, and the results of each task were calculated using the geometric mean method. Then, each score was converted to a 5-point scale ranging from 0 to 1.
성능/효과
For the quantitative assessment, the results for the speed of execution showed that eight items, apart from the “pick-up and move a jar” item, were different between the impaired group and healthy group.
The result of the discriminant validity test indicated that TEMPA is an assessment tool, which can clearly distinguish individuals with upper extremity impairments from those without impairments. The reliability test result showed that TEMPA has a moderate to high test-retest reliability score and moderate to high inter-rater reliability score.

The results of our study indicated that TEMPA can be used to obtain more detailed information of the participants’ upper extremity functions.
The results of the speed of execution showed that the healthy group competed all tasks faster than the impaired group, except the “pick-up and move a jar” task, and the difference was statistically significant (p<.05).
