Abstract

Background and objectives: To better inform service provision and social services, Australia has long needed a comprehensive national ageing study that is comparable with international ageing studies and eligible to join the register of harmonized cross-national studies of ageing. We conducted a pilot study to fill this gap in Australia's social and health data collection on ageing.

Research design and methods: We utilized online computer-assisted web interviewing (CAWI) and a follow-up Telephone Interview for Cognitive Status (TICS) screening. Participants were drawn from a Roy Morgan Consumer Panel using random probability sampling. Data collected were compared with the national Census data.

Results: Among 1172 online CAWI survey participants (mean age: 65.8 years; 51.0% female), 46.8% had a chronic health condition or disability, 26.1% were full-time employed, and 46.8% were fully or partially retired. Compared with 2021 Australian Census data, the sample was broadly representative by age, sex, geographic region, and health, but respondents tended to have higher education levels (66% reported completing secondary schooling vs 42% in the Census) and underrepresented culturally and linguistically diverse backgrounds (21% born overseas vs 39%; 4% speak a language other than English at home vs 23%); 804 respondents completed TICS (mean[SD] = 33.6[2.8]; range: 22-41), with 71.4% classified as cognitively normal, 27.7% ambiguous, and 1.1% cognitively impaired.

Discussion and implications: This pilot demonstrated the feasibility of online and telephone-based data collection with cognitive screening to capture demographic and health profiles of older Australians, providing a strong foundation for future large-scale national ageing studies.

一项国家试点研究，为澳大利亚老龄问题纵向跨学科国家数据的设计提供信息。

背景和目标：为了更好地为服务提供和社会服务提供信息，澳大利亚长期以来一直需要一项与国际老龄化研究相媲美的全面的全国老龄化研究，并有资格加入统一的跨国老龄化研究登记册。我们进行了一项试点研究，以填补澳大利亚关于老龄化的社会和健康数据收集方面的空白。研究设计和方法：我们使用在线计算机辅助网络访谈（CAWI）和随访电话访谈进行认知状态（TICS）筛查。参与者是从罗伊摩根消费者小组中抽取的，采用随机概率抽样。收集的数据与全国人口普查数据进行了比较。结果：在1172名在线CAWI调查参与者中（平均年龄：65.8岁，51.0%为女性），46.8%患有慢性健康状况或残疾，26.1%为全职工作，46.8%为完全或部分退休。与2021年澳大利亚人口普查数据相比，该样本在年龄、性别、地理区域和健康状况方面具有广泛代表性，但受访者往往受过高等教育（66%报告完成中学教育，人口普查为42%），文化和语言多样性背景的代表性不足（21%出生在海外，39%；4%在家说英语以外的语言，23%）；804名受访者完成了TICS (mean[SD] = 33.6[2.8]；范围：22-41)，其中71.4%的人认知正常，27.7%的人认知模糊，1.1%的人认知受损。讨论和影响：该试点项目证明了利用认知筛选进行在线和电话数据收集以获取澳大利亚老年人的人口和健康概况的可行性，为今后大规模的全国老龄化研究提供了坚实的基础。

期刊介绍： Innovation in Aging, an interdisciplinary Open Access journal of the Gerontological Society of America (GSA), is dedicated to publishing innovative, conceptually robust, and methodologically rigorous research focused on aging and the life course. The journal aims to present studies with the potential to significantly enhance the health, functionality, and overall well-being of older adults by translating scientific insights into practical applications. Research published in the journal spans a variety of settings, including community, clinical, and laboratory contexts, with a clear emphasis on issues that are directly pertinent to aging and the dynamics of life over time. The content of the journal mirrors the diverse research interests of GSA members and encompasses a range of study types. These include the validation of new conceptual or theoretical models, assessments of factors impacting the health and well-being of older adults, evaluations of interventions and policies, the implementation of groundbreaking research methodologies, interdisciplinary research that adapts concepts and methods from other fields to aging studies, and the use of modeling and simulations to understand factors and processes influencing aging outcomes. The journal welcomes contributions from scholars across various disciplines, such as technology, engineering, architecture, economics, business, law, political science, public policy, education, public health, social and psychological sciences, biomedical and health sciences, and the humanities and arts, reflecting a holistic approach to advancing knowledge in gerontology.
