本文描述了生活质量自述量表（CASP-19）的概念发展，并结合探索性和验证性因素分析方法，针对新千年生活在英格兰和威尔士的老年人的三种不同调查环境，对其结构进行了实证评估。所有评估都是使用 MPlus 进行的，它允许分析师评估一组多元分类项目的量表属性，这些项目不受项目无响应的影响。 CASP-19 是一种主观幸福感衡量标准，源自人类需求的明确理论，涵盖四个生活领域：控制、自主、自我实现和快乐。正式地说，CASP-19 是一个自我报告的总结性指数，由 19 个李克特量表项目组成。这三项调查包括对 263 名处于老年早期的人进行的邮政调查，受访者在 1930 年代首次接受采访时就进行了跟踪调查，英国老龄化纵向研究 (ELSA_1) 的第一波（2002 年）和英国家庭小组调查 (BHPS_11) 也于 2002 年进行了第十一波。这些具有全国代表性的调查包括 9300 名和 6471 名老年受访者。 55 岁及以上。 Boyd-Orr 样本为评估提供了探索性背景，ELSA_1 与 BHPS_11 一起提供了对三种测量模型进行验证性分析的机会。有人支持使用 CASP-19 作为独立的总结性指数。然而，分析表明，分析师推荐的模型是在二阶测量模型中结合生命领域“控制和自主”的缩短的 12 项量表。这项工作是由英国经济和社会研究委员会的老龄化计划及其人类能力和复原力优先网络资助的。授权号 L480254016 和 L326253061。
This paper describes the conceptual development of a self-enumerated scale of quality of life (CASP-19) and presents an empirical evaluation of its structure using a combination of exploratory and confirmatory factor analytic approaches across three different survey settings for older people living in England and Wales in the new millennium. All evaluations are conducted using MPlus which allows the analyst to evaluate the properties of the scale for a set of multivariate categorical items which are subject to item non-response. CASP-19 is a subjective measure of well-being derived from an explicit theory of human need spanning four life domains: control, autonomy, self-realisation and pleasure. Put formally, CASP-19 is a self-reported summative index consisting of 19 Likert scale items. The three survey settings include a postal survey of 263 people in early old age followed up from childhood when the respondents were first interviewed in the 1930's, the first wave (2002) of the English Longitudinal Study of Ageing (ELSA_1) and the eleventh wave of the British Household Panel Survey (BHPS_11) also conducted in 2002. These nationally representative surveys consisted of 9300 and 6471 respondents aged 55 years and older. The Boyd-Orr sample provides an exploratory context for the evaluation and ELSA_1 together with BHPS_11 provide the opportunity for confirmatory analyses of three measurement models. There is some support for the use of CASP-19 as a stand alone summative index. However, the analysis reveals that a shortened 12-item scale which combines the life domains 'control and autonomy' in a second order measurement model is the recommended model for analysts.
