成人社会护理成果工具包（阿斯科特）包括一个偏好加权的衡量社会护理相关的生活质量，用于经济评估。阿斯科特有八个属性：个人清洁和舒适、食物和饮料、日常生活控制、个人安全、住宿清洁和舒适、社会参与和参与、职业和尊严。本文旨在证明阿斯科特属性的结构效度。一项对接受公共资助的家庭护理服务的老年人的调查是在英格兰的几个地点通过面对面的访谈进行的。还收集了假设与每个属性相关和不相关的变量的其他数据。通过卡方检验和方差分析（如适用）分析这些变量与属性之间的关系，以检验每个属性的结构效度。301人接受了采访，大约10%的回答是由代理回答者给出的。结果表明，每个属性捕获的程度，受访者行使选择如何满足他们的结果。还有证据表明，日常生活，职业，个人清洁和舒适，个人安全，住宿清洁和舒适，社会参与和参与属性的控制的有效性。关于食品和饮料以及尊严属性的有效性的证据较少，但这可能是由于难以找到用于验证这些属性的良好数据，以及食品和饮料的分配问题。本研究为阿斯科特属性的结构效度提供了一些证据，从而为阿斯科特在经济评价中的应用提供了支持。它还证明了在老年人中使用的可行性，尽管在某些情况下需要代理答卷人，这表明开发一个适合代理人的版本将是这项工作今后的一个有益方向。对年轻社会护理使用者样本的仪器验证也将是有用的。
The adult social care outcomes toolkit (ASCOT) includes a preference-weighted measure of social care-related quality of life for use in economic evaluations. ASCOT has eight attributes: personal cleanliness and comfort, food and drink, control over daily life, personal safety, accommodation cleanliness and comfort, social participation and involvement, occupation and dignity. This paper aims to demonstrate the construct validity of the ASCOT attributes. A survey of older people receiving publicly-funded home care services was conducted by face-to-face interview in several sites across England. Additional data on variables hypothesised to be related and unrelated to each of the attributes were also collected. Relationships between these variables and the attributes were analysed through chi-squared tests and analysis of variance, as appropriate, to test the construct validity of each attribute. 301 people were interviewed and approximately 10% of responses were given by a proxy respondent. Results suggest that each attribute captured the extent to which respondents exercised choice in how their outcomes were met. There was also evidence for the validity of the control over daily life, occupation, personal cleanliness and comfort, personal safety, accommodation cleanliness and comfort, and social participation and involvement attributes. There was less evidence regarding the validity of the food and drink and dignity attributes, but this may be a consequence of problems finding good data against which to validate these attributes, as well as problems with the distribution of the food and drink item. This study provides some evidence for the construct validity of the ASCOT attributes and therefore support for ASCOT's use in economic evaluation. It also demonstrated the feasibility of its use among older people, although the need for proxy respondents in some situations suggests that developing a version that is suitable for proxies would be a useful future direction for this work. Validation of the instrument on a sample of younger social care users would also be useful.
