Improving the quality of life (QoL) of older people is a key priority for governments, clinicians, researchers and service providers worldwide. However, the lack of culturally appropriate QoL tools for First Nations people is a major barrier to such efforts. The purpose of this study was to evaluate the psychometric properties of the Good Spirit, Good Life (GSGL) QoL tool for older Aboriginal Australians.
One hundred and twenty older Aboriginal people living in Perth and Melbourne, Australia, were administered the GSGL tool, along with several other instruments assessing cognition (KICA-Cog), depression (KICA-Dep), anxiety (GAI-SF), health and well-being (EQ-5D-5L and ICECAP-O) and resilience (ARRQ-25). Associations between these instruments and the GSGL tool were explored to determine concurrent and known-groups validity. Internal consistency was assessed with split-half reliability and Cronbach's alpha. Exploratory factor analysis was performed to investigate construct validity.
GSGL scores were positively correlated with ICECAP-O and ARRQ-25 scores, and negatively correlated with EQ-5D-5L score. GSGL scores differed significantly between participants with a probable anxiety disorder or depression, but not those with cognitive impairment. The Spearman-Brown prophecy estimate was 0.83 and Cronbach's alpha was 0.75. Principal component analysis identified two factors, which were labelled foundation and external.
The GSGL tool is a valid tool to assess quality of life in older Aboriginal Australians. The tool demonstrates acceptable convergent, concurrent and known-groups validity. It was co-designed at all stages with older Aboriginal people contributing to its strong face and content validity.
提高老年人的生活质量（QoL）是世界各国政府、临床医生、研究人员和服务提供商的首要任务。然而，缺乏适合原住民的 QoL 工具是实现这一目标的主要障碍。本研究旨在评估专为澳大利亚老年原住民设计的“美好精神，美好生活”（GSGL）QoL 工具的心理测量特性。
在澳大利亚珀斯和墨尔本，120 名老年原住民接受了 GSGL 工具的评估，同时还评估了其他几种工具，包括认知能力（KICA-Cog）、抑郁（KICA-Dep）、焦虑（GAI-SF）、健康和幸福感（EQ-5D-5L 和 ICECAP-O）和韧性（ARRQ-25）。探索这些工具与 GSGL 工具之间的关联，以确定同时存在的有效性和已知群体的有效性。采用分半信度和克朗巴赫的 alpha 来评估内部一致性。进行探索性因子分析以检验结构有效性。
GSGL 评分与 ICECAP-O 和 ARRQ-25 评分呈正相关，与 EQ-5D-5L 评分呈负相关。GSGL 评分在有疑似焦虑症或抑郁症的参与者之间存在显著差异，但在有认知障碍的参与者之间没有显著差异。Spearman-Brown 预测值为 0.83，克朗巴赫的 alpha 为 0.75。主成分分析确定了两个因素，分别命名为基础和外部。
GSGL 工具是评估澳大利亚老年原住民生活质量的有效工具。该工具具有可接受的收敛性、同时存在的有效性和已知群体的有效性。该工具在所有阶段都与老年原住民共同设计，使其具有很强的表面和内容有效性。
