老年人的健康状况不断改善，生活方式不断变化，因此有必要制定一个能够更好地衡量他们在更高水平上的能力的量表。我们通过项目分析开发了日本科学技术机构能力指数（JST-IC），并评估了其心理测量学特性。参与者是1306名社区老年人（男性623名，女性683名，74.0 ± 2.8岁），他们完成了54个项目的JST-IC草案，以确定他们的独立水平。三个程序经项目筛选、因素分析、信度和效度分析，最终确定了JST-IC量表，并对其进行了心理测量学评价。（a）15个，因为比率很高（80%或以上）回答“是”的应答者，（B）1人因性别差异（phi系数= 0.34），（c）5名，因为他们与东京都老年学研究所能力指数的联系不强（Pearson相关系数为0.30或更小），以及（d）由于与其他项目的意义冗余而为5。通过因素分析，我们选择了16个项目的四个因素的解决方案，为最终版本。JST-IC得分呈近似正态分布，且存在显著的性别和年龄差异，与社会网络规模和主观幸福感水平呈中度相关，与TMIG-IC得分、身体素质和健康素养呈强相关，JST-IC有助于评估社区老年人更高水平的能力。
Older adults' ever-improving health and changing lifestyles necessitate the development of a scale that can better measure their competence at a higher level. We developed the Japan Science and Technology Agency Index of Competence (JST-IC) via item analysis and assessed its psychometric properties.Participants were 1306 community-dwelling older adults (623 men and 683 women, 74.0 +/- 2.8 years old) who completed the 54-item draft JST-IC to determine their level of independence. Three procedures (including item selection, factor analyses, and reliability and validity analyses) were conducted to finalize the JST-IC and evaluate its psychometric properties.The item selection resulted in exclusion of 26 items for the following reasons: (a) 15 because of very high ratios (80% or more) of responders who answered "yes", (b) one because of gender differences (phi coefficient = 0.34), (c) five because of their weak association with the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) (Pearson correlation coefficient of 0.30 or smaller), and (d) five because of redundancy of meaning with other items. Through factor analyses, we selected 16 items with a four-factor solution for the final version. JST-IC score exhibited a near-normal distribution and significant gender and age differences, and had moderate correlations with size of social network and level of subjective well-being and strong correlations with TMIG-IC score, physical fitness, and health literacy.The JST-IC is useful for assessing competence at a higher level in community-dwelling older adults.
