Rheumatoid arthritis (RA) is an auto-immune disease accompanied by systemic complications affecting the major body organs including the heart, lungs, and blood vessels, joint pain, spasticity, and edema, as well as inducing permanent joint deformity and malformation (1). In patients with RA, anxiety and depression are common, compared to the general population and have been associated with fatigue, pain, and health care costs (2). Worse physical health can lead to mental problems (3). Reciprocally, mental health problems can also impact on physical activity (4). Thus, it is important that these problems are recognized, to ensure suitable psychological treatment and appropriate management of RA. In general, regular exercise has been robustly associated with positive physical and psychological health (5). Many experimental studies indicate higher levels of exercise engagement to lead to improvements in inflammatory disease activity, physical function, and mental health (6-8). Patients with RA are restricted from exercise and activity for a variety of reasons (9). The major reasons behind the lack of exercise including Abstract Background: Despite the awareness that regular exercise has a positive impact on maintaining health, patients with rheumatoid arthritis (RA) engage in markedly less exercise than do the general population. Weaimed to construct and test a structural equation model of exercise behavior in patients with RA based on selfdetermination theory and self-efficacy theory. Methods: Participants were 214 outpatients with RA at Chonnam National University Hospital located in the Gwangju City, South Korea from Mar to Apr 2018. A structured self-report questionnaire was used to assess autonomy support, autonomy, competence, relatedness, autonomous motivation, self-efficacy, and exercise behavior. Collected data were analyzed using SPSS 22.0 and AMOS 22.0 program. Results: The structural model showed a good fitness with the data (χ2= 727.27, df = 392, P<0.001, TLI = 0.92, CFI = 0.93, RMSEA = 0.07, SRMR = 0.07). Autonomous motivation and self-efficacy had a significant effect on exercise behavior in patients with RA. This model explained 21.2% of the variance of exercise behavior in patients with RA. Conclusion: Self-efficiency and autonomous motivation should be promoted in order to strengthen the exercise behavior of patients with RA.

类风湿关节炎患者运动行为模型的构建

类风湿性关节炎 (RA) 是一种自身免疫性疾病，伴有全身性并发症，影响主要身体器官，包括心脏、肺和血管，关节疼痛、痉挛和水肿，并导致永久性关节畸形和畸形 (1) . 与普通人群相比，RA 患者的焦虑和抑郁很常见，并且与疲劳、疼痛和医疗保健费用有关 (2)。身体健康状况不佳会导致精神问题 (3)。反过来，心理健康问题也会影响身体活动 (4)。因此，重要的是要认识到这些问题，以确保对 RA 进行适当的心理治疗和适当的管理。一般来说，定期锻炼与积极的身心健康密切相关 (5)。许多实验研究表明，更高水平的运动参与可以改善炎症性疾病活动、身体机能和心理健康 (6-8)。由于各种原因，RA 患者的运动和活动受到限制 (9)。缺乏运动背后的主要原因包括摘要背景：尽管意识到定期运动对维持健康有积极影响，但类风湿关节炎 (RA) 患者的运动量明显低于普通人群。旨在基于自我决定理论和自我效能理论构建并检验RA患者运动行为的结构方程模型。方法：参与者是 2018 年 3 月至 4 月在位于韩国光州市的全南国立大学医院的 214 名 RA 门诊患者。结构化的自我报告问卷用于评估自主支持、自主、能力、相关性、自主动机、自我效能和锻炼行为。使用 SPSS 22.0 和 AMOS 22.0 程序分析收集的数据。结果：结构模型与数据具有良好的拟合度（χ2= 727.27，df = 392，P<0.001，TLI = 0.92，CFI = 0.93，RMSEA = 0.07，SRMR = 0.07）。自主动机和自我效能对RA患者的运动行为有显着影响。该模型解释了 RA 患者运动行为差异的 21.2%。结论：应促进自我效能和自主动机，以加强RA患者的运动行为。和运动行为。使用 SPSS 22.0 和 AMOS 22.0 程序分析收集的数据。结果：结构模型与数据具有良好的拟合度（χ2= 727.27，df = 392，P<0.001，TLI = 0.92，CFI = 0.93，RMSEA = 0.07，SRMR = 0.07）。自主动机和自我效能对RA患者的运动行为有显着影响。该模型解释了 RA 患者运动行为差异的 21.2%。结论：应促进自我效能和自主动机，以加强RA患者的运动行为。和运动行为。使用 SPSS 22.0 和 AMOS 22.0 程序分析收集的数据。结果：结构模型与数据具有良好的拟合度（χ2= 727.27，df = 392，P<0.001，TLI = 0.92，CFI = 0.93，RMSEA = 0.07，SRMR = 0.07）。自主动机和自我效能对RA患者的运动行为有显着影响。该模型解释了 RA 患者运动行为差异的 21.2%。结论：应促进自我效能和自主动机，以加强RA患者的运动行为。自主动机和自我效能对RA患者的运动行为有显着影响。该模型解释了 RA 患者运动行为差异的 21.2%。结论：应促进自我效能和自主动机，以加强RA患者的运动行为。自主动机和自我效能对RA患者的运动行为有显着影响。该模型解释了 RA 患者运动行为差异的 21.2%。结论：应促进自我效能和自主动机，以加强RA患者的运动行为。
