Improvement in the health of older people and changes in their lifestyles necessitate a scale that can better measure their competence at a higher level. This study describes the development process of the Japan Science and Technology Agency Index of Competence (JST-IC) by (a) refining conceptual definitions and developing preliminary items and (b) examining the basic properties of the items. Participants were 1,253 septuagenarians (539 men and 714 women) living in communities, who were asked to judge whether they were independent via 88 items. To examine the basic properties of the preliminary items, five different analyses were conducted. Thirty-four items were considered as inappropriate (6 overlapped between the analyses): (a) 9 due to very high or low ratios of responders who answered "yes," (b) 4 due to gender or regional differences, (c) 5 due to their weak association with health status, (d) 9 due to low communalities in factor analysis, and (e) 13 due to redundancy of meaning with other items. Conceptual definitions and preliminary items were developed, and the basic properties of the items were examined to create the JST-IC. The next step would be to screen the remaining 54 items to create the final version of the scale.
老年人健康状况的改善及其生活方式的变化，需要一种能够在更高水平上更好地衡量其能力的量表。本研究描述了日本科学技术振兴机构能力指数（JST-IC）的开发过程，包括（a）完善概念定义并制定初步条目，以及（b）检验条目的基本属性。参与者为1253名居住在社区的七十多岁老人（539名男性和714名女性），他们被要求通过88个条目来判断自己是否具备自理能力。为了检验初步条目的基本属性，进行了五种不同的分析。34个条目被认为不合适（各分析之间有6个重叠）：（a）9个是因为回答“是”的应答者比例过高或过低，（b）4个是因为存在性别或地区差异，（c）5个是因为它们与健康状况的关联较弱，（d）9个是因为在因子分析中共同度较低，（e）13个是因为与其他条目存在意义冗余。通过完善概念定义和制定初步条目，并检验条目的基本属性，创建了JST-IC。下一步将筛选其余54个条目，以创建该量表的最终版本。
