To translate and culturally adapt the Physical Activity Scale for Elderly into Urdu, and to assess reliability and validity.
The descriptive, analytical study was conducted from March 2023 to January 2024 at Riphah International University, Islamabad, Pakistan, and comprised healthy individuals of either gender aged at least 60 years who were enrolled from the Safari Hospital, Islamabad. The Physical Activity Scale for Elderly was tested for validity and reliability, while its translation and cultural adaptation were done in accordance with the Consensus-Based Standards for the Selection of Health Status Measurement Instruments guidelines. For face and content validity, Percent Agreement and Content Validity Index at scale and item levels were determined. Internal consistency and test-retest reliability was evaluated using Cronbach's alpha and Intraclass Correlation Coefficient. Pearson's correlation coefficient was used to assess concurrent validity. Data was analysed using SPSS 27.
Of the 300 subjects, 163(54.3%) were males and 137(45.7%) were females. The overall mean age was 65.71±5.82 years (range: 60-80 years). Intraclass Correlation Coefficient 0.98 showed outstanding test-retest reliability. Cronbach's alpha value was 0.98 for the total, and for the items it was 0.99, 0.99 and 1. Face validity items 4, 7 and 9(a, d) were answered by 12 experts and 11(92%) of them answered in the affirmative, while items 1-3, 5- 9(b, c) and 10 were answered in the affirmative by 12(100%). Content validity index at item level was >0.9, and at scale it was 0.76. Concurrent Validity, Pearson correlation coefficient values were 0.78 for Berg Balance Scale-Urdu, and 0.74 for Activities-specific Balance Confidence Scale-Urdu, showing a strong positive correlation, while there was a very strong negative correlation with Time Up and Go Test (-0.70) and Five Times Sit To Stand test (-0.71). Principal Component Analysis revealed 4 factors based on eigenvalues >1 for the Urdu version of Physical Activity Scale for Elderly, with (Kaiser-Meyer-Olkin's value 0.708. These 4 components explained 68.31% of total variance.
The Urdu version of the Physical Activity Scale for Elderly was found to be a valid and reliable tool for evaluating physical activity level in older Pakistani adults.
将《老年人身体活动量表》翻译成乌尔都语并进行文化调适，同时评估其信效度。
2023年3月至2024年1月在巴基斯坦伊斯兰堡的里法国际大学开展了描述性分析研究，纳入了至少60岁的健康个体，他们均来自伊斯兰堡的萨法里医院，男女不限。对《老年人身体活动量表》进行效度和信度测试，并按照《基于共识的健康状况测量工具选择标准》指南进行翻译和文化调适。对于表面效度和内容效度，确定了量表和条目层面的百分比一致性和内容效度指数。使用克朗巴哈α系数和组内相关系数评估内部一致性和重测信度。采用皮尔逊相关系数评估同时效度。使用SPSS 27对数据进行分析。
300名受试者中，163名（54.3%）为男性，137名（45.7%）为女性。总体平均年龄为65.71±5.82岁（范围：60 - 80岁）。组内相关系数为0.98，显示出出色的重测信度。总量表的克朗巴哈α值为0.98，各条目分别为0.99、0.99和1。12名专家对表面效度条目4、7和9（a、d）进行了回答，其中11名（92%）回答为是，而条目1 - 3、5 - 9（b、c）和10的回答为是的比例为12名（100%）。条目层面的内容效度指数>0.9，量表层面为0.76。同时效度方面，乌尔都语版伯格平衡量表的皮尔逊相关系数值为0.78，乌尔都语版特定活动平衡信心量表为0.74，显示出强正相关，而与起立行走测试（-0.70）和五次坐立测试（-0.71）呈非常强的负相关。主成分分析显示，基于乌尔都语版《老年人身体活动量表》特征值>1提取出4个因子（凯泽 - 迈耶 - 奥尔金值为0.708）。这4个成分解释了总方差的68.31%。
乌尔都语版《老年人身体活动量表》是评估巴基斯坦老年成年人身体活动水平的有效且可靠工具。
