背景能力指数(ICECAP)是通过对40名老年人的深入访谈编制的，包括五个属性：依恋、安全、享受、角色和控制。本文探讨了这五种能力属性的结构效度。方法对英国各地65岁及以上的老年人进行访谈调查。采用卡方检验(分类变量)或单因素方差分析(连续变量)对数据进行6类分析(社会人口学变量和总体幸福感、与他人接触、健康、地区和环境性质、社会支持和参与)。结果共访问了约315人(回复率为66%)。人际关系总体上符合预期：年龄和能力与幸福感和能力之间存在较强的相关关系，而能力与性别和社会阶层之间没有关系；身体健康指标与角色、享受和控制之间以及心理健康指标与依恋和享受之间存在较强的关系。结论本研究为ICECAP量表的结构效度提供了一些早期证据。如果没有观察到预期的关系，这可能部分是因为ICECAP指数询问的是能力，但审查关联的因素在很大程度上不可避免地是功能的衡量标准。
Background The index of capability (ICECAP) was developed using in-depth interviews with 40 older people and comprises five attributes: attachment, security, enjoyment, role and control. This paper explores the construct validity of these five capability attributes.Methods An interview survey was conducted with individuals aged 65 and over located across the UK. Data were analysed in six categories (socio-demographic variables and general well-being, contact with others, health, nature of the locality and environment, social support and participation) using chi-squared tests (for categorical variables) or one-way analysis of variance (for continuous variables).Results About 315 individuals were interviewed (response rate 66%). Relationships were generally as anticipated with, for example: strong relationships between age and capability and well-being and capability, but no relationships between capability and either sex or social class; strong relationships between physical measures of health and role, enjoyment and control, and between mental health measures and attachment and enjoyment.Conclusions This study provides some early evidence for the construct validity of the ICECAP measure. Where anticipated relationships were not observed this might in part be explained in that the ICECAP index asks about capability, but the factors with which associations were examined were largely and inevitably measures of function.
