To evaluate the construct (convergent and known group) validity of the Quality-of-Life-Aged Care Consumer (QOL-ACC), an older-person-specific quality-of-life measure designed for application in quality assessment and economic evaluation in aged care.
Convergent validity was assessed by examining relationships with other validated preference-based measures (EQ-5D-5L, ASCOT), quality of aged care experience (QCE-ACC) and life satisfaction (PWI) through an online survey. Known-group validity was assessed by testing the ability to discriminate varying levels of care needs, self-reported health and quality of life.
Older people (aged ≥ 65 years) receiving community-aged care (N = 313) responded; 54.6% were female, 41.8% were living alone and 56.8% were receiving higher-level care. The QOL-ACC and its six dimensions were low to moderately and significantly correlated with the EQ-5D-5L (correlation co-efficient range, ρ = 0.39-0.56). The QOL-ACC demonstrated moderate and statistically significant correlations with ASCOT (ρ = 0.61), the QCE-ACC (ρ = 0.51) and the PWI (ρ = 0.70). Respondents with poorer self-reported health status, quality of life and/or higher-level care needs demonstrated lower QOL-ACC scores (P < 0.001), providing evidence of known-group validity.
The study provides evidence of the construct validity of the QOL-ACC descriptive system. A preference-weighted value set is currently being developed for the QOL-ACC, which when finalised will be subjected to further validation assessments.
评估专为老年护理质量评估和经济评估应用而设计的老年人特定生活质量衡量标准——生活质量老年护理消费者（QOL-ACC）的结构（收敛和已知组）有效性。
通过在线调查，评估与其他经过验证的偏好衡量标准（EQ-5D-5L、ASCOT）、老年护理体验质量（QCE-ACC）和生活满意度（PWI）的关系，评估收敛有效性。通过测试区分不同护理需求水平、自我报告的健康和生活质量的能力，评估已知组有效性。
参与调查的是接受社区老年护理的老年人（年龄≥65 岁，N=313）；54.6%为女性，41.8%独居，56.8%接受更高层次的护理。QOL-ACC 及其六个维度与 EQ-5D-5L 呈低度至中度显著相关（相关系数范围，ρ=0.39-0.56）。QOL-ACC 与 ASCOT（ρ=0.61）、QCE-ACC（ρ=0.51）和 PWI（ρ=0.70）具有中度且具有统计学意义的相关性。自我报告健康状况、生活质量较差和/或护理需求较高的受访者的 QOL-ACC 得分较低（P<0.001），这提供了已知组有效性的证据。
该研究为 QOL-ACC 描述性系统的结构有效性提供了证据。目前正在为 QOL-ACC 开发偏好加权值集，完成后将对其进行进一步的验证评估。
