As stroke patients may have impaired motor function, there may have increased sedentary behavior. Factors associated with sedentary behavior need to be explored to develop targeted interventions. Although studies explore the effects of exercise self-efficacy and perceived social support on sedentary behavior, the relationship is not clear. The aim of this study was to explore the mediating effect of exercise self-efficacy on perceived social support and objective measured sedentary behavior in stroke patients.
The random sampling method was adopted to select 275 stroke patients from the neurology department of a third-grade hospital of Henan Province from June 2023 to March 2024 in a cross-sectional descriptive study. A general data questionnaire, exercise self-efficacy scale, perceived social support scale, and ActiGraph GT3X accelerometer were used to investigate. The structural equation model was used to analyze the mediating effect of exercise self-efficacy between perceived social support and sedentary behavior.
The mean sedentary behavior time in stroke patients in this study was (479.65 ± 112.65) min, the mean score of perceived social support was (47.53 ± 17.16), and the mean score of exercise self-efficacy was (24.19 ± 6.25). The correlation analysis revealed that, the sedentary behavior of stroke patients was negatively correlated with exercise self-efficacy and perceived social support. The results of the mediation analysis showed that exercise self-efficacy played a partial mediating role between perceived social support and sedentary behavior.
Perceived social support and exercise self-efficacy were influential factors in sedentary behavior. Moreover, the impact of perceived social support on sedentary behavior was partially mediated by exercise self-efficacy. Therefore, to decrease the sedentary behavior, it is crucial to improve the level of perceived social support in stroke patients. Patients with less perceived social support can improve their exercise self-efficacy and thus perceive more social support.
由于中风患者可能存在运动功能受损的情况，久坐行为可能会增加。需要探索与久坐行为相关的因素，以制定有针对性的干预措施。尽管有研究探讨了运动自我效能感和感知社会支持对久坐行为的影响，但其关系尚不清楚。本研究的目的是探讨运动自我效能感在中风患者感知社会支持与客观测量的久坐行为之间的中介作用。
在一项横断面描述性研究中，采用随机抽样方法，于2023年6月至2024年3月从河南省某三级医院神经内科选取275例中风患者。使用一般资料问卷、运动自我效能量表、感知社会支持量表和ActiGraph GT3X加速度计进行调查。采用结构方程模型分析运动自我效能感在感知社会支持与久坐行为之间的中介作用。
本研究中中风患者的平均久坐行为时间为（479.65±112.65）分钟，感知社会支持的平均得分为（47.53±17.16），运动自我效能感的平均得分为（24.19±6.25）。相关分析显示，中风患者的久坐行为与运动自我效能感和感知社会支持呈负相关。中介分析结果表明，运动自我效能感在感知社会支持与久坐行为之间起部分中介作用。
感知社会支持和运动自我效能感是久坐行为的影响因素。此外，感知社会支持对久坐行为的影响部分通过运动自我效能感介导。因此，为了减少久坐行为，提高中风患者的感知社会支持水平至关重要。感知社会支持较少的患者可以提高其运动自我效能感，从而感知到更多的社会支持。
