最近的研究表明，活动的广度和均匀性以及活动的多样性有助于老年人的健康结果。然而，很少有既定的活动多样性评估工具已经开发。本研究通过专家咨询和对18名社区老年人的初步调查，编制了老年人活动多样性问卷（ADQ）。根据Shannon熵计算多样性得分。在研究1中，确定了社区居住的老年人（n = 30）的多样性得分的组内相关系数（ICC）。在研究2中，对2018年在日本板桥病房接受全面健康检查的参与者（n = 766）进行了同步有效性测试。多样性得分的相关系数，然后计算参考东京都老年学研究所的能力指数和日本科学技术机构的能力指数。ADQ的最终版本由20个项目组成，具有良好的重测信度（ICC = 0.84）和中度相关的东京都老年学研究所能力指数和日本科学技术厅能力指数（r = 0.48和0.60，分别）。ADQ是通过科学程序开发的，具有足够的可靠性和有效性。因此，它是一种经过科学验证的评估老年人活动多样性的工具。
Recent research has suggested that the breadth and evenness of activity and activity diversity contribute to health outcomes among older adults. However, few established assessment tools for activity diversity have been developed. This study developed an Activity Diversity Questionnaire (ADQ) for older adults through expert consultation and a preliminary survey among 18 community-dwelling older adults. The diversity score was calculated according to Shannon's entropy. In study 1, the intraclass correlation coefficients (ICC) of the diversity scores were determined for community-dwelling older adults (n = 30). In study 2, concurrent validity was tested with participants receiving comprehensive health checkups at the Itabashi ward in Japan in 2018 (n = 766). The correlation coefficients of the diversity scores were then calculated in reference to the Tokyo Metropolitan Institute of Gerontology Index of Competence and Japan Science and Technology Agency Index of Competence. The final version of the ADQ consisted of 20 total items with excellent test-retest reliability (ICC = 0.84) and moderate correlations with both the Tokyo Metropolitan Institute of Gerontology Index of Competence and Japan Science and Technology Agency Index of Competence (r = 0.48 and 0.60, respectively). The ADQ was developed through scientific procedures and revealed sufficient reliability and validity. As such, it is a scientifically validated tool for assessing activity diversity among older adults.
