The University of Jyvaskyla Active Aging Scale (UJACAS) assesses active aging through willingness, ability, opportunity, and frequency of involvement in activities. Recognizing the lack of a German version, the Finnish original was translated (UJACAS-G). This study aimed: (1) to evaluate the test-retest reliability of UJACAS-G; and (2) to explore correlations with health-related parameters (concurrent validity).
The study (test-retest design) targeted healthy older adults aged 65+. Reliability of UJACAS-G (total and subscores) was assessed using Bland-Altman analyses and Intraclass Correlation Coefficients (ICCs). Furthermore, correlations (Spearman's rho) between UJACAS-G scores and physical function (walking speed, handgrip strength, balance, 6-minute walk distance), physical activity (International Physical Activity Questionnaire), life-space mobility (Life-Space Assessment), and health-related quality of life (Short Form-36 Health Survey) were calculated.
Bland-Altman analyses (N = 60; mean age 72.3, SD 5.9 years; 50% women) revealed mean differences close to zero and narrow limits of agreement for all scores (total score: mean difference -1.9; limits -31.7 to 27.9). The ability subscore showed clustering at its upper limit. ICC was 0.829 (95% CI 0.730 to 0.894) for the total score and ranged between 0.530 and 0.876 for subscores (all p-values < 0.001). The total score correlated with walking speed (rho = 0.345; p = 0.008), physical activity (rho = 0.279; p = 0.033) and mental health (rho = 0.329; p = 0.010).
UJACAS-G is reliable for assessing active aging among German-speaking healthy older adults. A potential 'ceiling effect' regarding the ability subscore should be considered when applying UJACAS-G to well-functioning populations. Analyses of concurrent validity indicated only weak correlations with health-related parameters.
于韦斯屈莱积极老龄化量表（UJACAS）通过意愿、能力、机会和参与活动的频率来评估积极老龄化。由于缺乏德语版本，芬兰原文被译为 UJACAS-G。本研究旨在：（1）评估 UJACAS-G 的重测信度；（2）探索与健康相关参数的相关性（同时效度）。
该研究（重测设计）以年龄在 65 岁以上的健康老年人为对象。使用 Bland-Altman 分析和组内相关系数（ICC）评估 UJACAS-G（总分和分量表）的重测信度。此外，还计算了 UJACAS-G 评分与身体功能（步行速度、握力、平衡、6 分钟步行距离）、身体活动（国际体力活动问卷）、生活空间移动性（生活空间评估）和健康相关生活质量（36 项简短健康调查）之间的相关性（Spearman rho）。
Bland-Altman 分析（N=60；平均年龄 72.3，SD 5.9 岁；50%为女性）显示，所有评分的平均差异接近零，且一致性界限较窄（总分：平均差异-1.9；界限-31.7 至 27.9）。能力分量表在上限处显示出聚类现象。总分为 0.829（95%CI 0.730 至 0.894），分量表范围在 0.530 至 0.876（所有 p 值均<0.001）。总分与步行速度（rho=0.345；p=0.008）、身体活动（rho=0.279；p=0.033）和心理健康（rho=0.329；p=0.010）呈正相关。
UJACAS-G 可用于评估德语地区健康老年人的积极老龄化情况，具有可靠性。在将 UJACAS-G 应用于功能良好的人群时，应考虑能力分量表的潜在“天花板效应”。同时效度分析表明，与健康相关参数的相关性较弱。
