To investigate the impact of different approaches for measuring 'successful ageing', four alternative researcher and participant definitions were compared, including a novel measure informed by cluster analysis. Rates of successful ageing were explored, as were their relative associations with age and measures of successful adaptation, to assess construct validity.
Participants, aged over 65, were recruited from community-based organisations. Questionnaires (assessing successful ageing, lifestyle activities and selective optimisation with compensation) were completed by 317 individuals.
Successful ageing ranged from 11.4% to 87.4%, with higher rates evident from participant definitions. Though dependent upon the definition, successful agers were typically younger, reported greater engagement with lifestyle activities and more frequent optimisation.
While the current study suggested an improved classification algorithm using a common research definition, future research should explore how subjective and objective aspects of successful ageing may be combined to derive a measure relevant to policy and practice.
为研究不同的“成功老龄化”衡量方法的影响，比较了四种不同的研究者定义和参与者定义，其中包括一种基于聚类分析的新方法。探讨了成功老龄化的比率及其与年龄和成功适应指标的相对关联，以评估结构效度。
从社区组织招募了65岁以上的参与者。317人完成了问卷（评估成功老龄化、生活方式活动以及选择性优化与补偿）。
成功老龄化的比率在11.4%至87.4%之间，从参与者定义来看比率更高。尽管取决于定义，但成功老龄化者通常更年轻，报告称更多地参与生活方式活动且更频繁地进行优化。
虽然当前研究提出了一种使用通用研究定义的改进分类算法，但未来研究应探索如何将成功老龄化的主观和客观方面结合起来，以得出与政策和实践相关的衡量方法。
