(1) Background: This study aims to put into evince the relationship between the variability of the reaction time (RT) during repeated testing, expressed through indicators extracted by the Poincaré plot method, and the age of the participants, their self-reported health (SRH), and level of perceived anxiety. (2) Methods: The study was performed using computerized RT testing software. An observational cross-sectional study was performed on a group of 120 subjects (mean age 42.33 ± 21.12 years), sex ratio men to women 1.14:1. Data were processed through descriptive and inferential statistics. The Poincaré plot method was applied in the analysis of the RT series of data, by calculating the indicators SD, SD, SD/SD, and area of the fitting ellipse (AFE) (3) Results: We provided evidence of the excellent reliability of the web-based RT serial testing (Cronbach's Alpha 0.991) with this sample group. Our results showed that age is an important predictor for mean values of RT, while SD, SD, and AFE indicators are for SRH ( < 0.01). (4) Conclusions: the variability of RT, expressed by the Poincaré plot indicators, reflects the health status rather than the aging of the subjects and is barely influenced by their level of anxiety.
(1) 背景：本研究旨在通过 Poincaré 图法提取的指标，展示重复测试中反应时（RT）变化与参与者年龄、自我报告健康状况（SRH）和感知焦虑水平之间的关系。(2) 方法：本研究使用计算机化 RT 测试软件进行。对 120 名受试者（平均年龄 42.33 ± 21.12 岁，男女比例为 1.14:1）进行了观察性横断面研究。通过描述性和推断性统计方法对数据进行处理。Poincaré 图法用于分析 RT 数据系列，计算指标 SD、SD、SD/SD 和拟合椭圆面积（AFE）。(3) 结果：我们为这个样本组提供了基于网络的 RT 系列测试（Cronbach's Alpha 0.991）具有极好可靠性的证据。我们的结果表明，年龄是 RT 均值的重要预测因素，而 SD、SD 和 AFE 指标则与 SRH 相关（<0.01）。(4) 结论：由 Poincaré 图指标表示的 RT 变化反映了受试者的健康状况，而不是年龄，并且几乎不受其焦虑水平的影响。
