Resilience, the ability to bounce back after adverse events may be an important factor in active aging. The 10-item version of the Connor-Davidson Resilience Scale (CD-RISC10) seems suitable for aging research owing to its low participant burden; however, its psychometric properties have not been comprehensively reported for older people. For example, no estimate exists of the test-retest reliability of the scale when used with older adults. Hence, this study evaluated the psychometric properties of the CD-RISC10 in a large population-based sample of community-dwelling older people.
The scale's internal consistency, factor structure, construct validity, test-retest reliability, and user experience were analyzed among 1018 Finnish older adults (57% women) aged 75 (45%), 80 (33%) and 85 years (22%).
The internal consistency of the CD-RISC10 was good (Cronbach's α = 0.85), test-retest reliability moderate (ICC = 0.61), and the scale was unidimensional. However, a two-factor solution was found among the 75-year-olds, where the ability to deal positively with change (e.g. using humor) explained an additional part of resilience. While no differences by gender, age, or education were observed in total scores, very good perceived financial situation was associated with higher resilience. The scale showed good construct validity, and user feedback indicated that administering the scale in research is quick and easy.
In general, the CD-RISC10 is a valid method to study older adults' psychological resilience. However, the present test-retest reliability values suggest caution in using the scale as an outcome measure in intervention studies.
韧性是指在遭受逆境后恢复的能力，它可能是积极老龄化的一个重要因素。Connor-Davidson 韧性量表（CD-RISC10）的 10 项版本由于其参与者负担较低，似乎适合衰老研究；然而，其心理测量学特性尚未在老年人中得到全面报道。例如，当用于老年人时，该量表的重测信度尚无估计值。因此，本研究在一个基于社区的大型老年人样本中评估了 CD-RISC10 的心理测量学特性。
本研究分析了 1018 名芬兰老年人（57%为女性）的量表内部一致性、结构、构念效度、重测信度和用户体验，这些老年人的年龄为 75（45%）、80（33%）和 85 岁（22%）。
CD-RISC10 的内部一致性良好（Cronbach's α=0.85），重测信度中等（ICC=0.61），且量表具有单维性。然而，在 75 岁的老年人中发现了两因素解决方案，其中积极应对变化的能力（例如使用幽默）解释了韧性的另外一部分。虽然在总分数上没有观察到性别、年龄或教育程度的差异，但非常好的经济状况与更高的韧性相关。该量表具有良好的结构效度，用户反馈表明，在研究中管理量表既快速又简单。
总的来说，CD-RISC10 是一种研究老年人心理韧性的有效方法。然而，目前的重测信度值表明，在干预研究中使用该量表作为结果测量时应谨慎。
