To examine whether patients who had a stroke with high recurrence risk perception would have healthier behaviour and to explore whether perceived social support would function as a mediator.
A cross-sectional study.
The study was conducted in a public tertiary hospital in China.
A total of 254 patients with stroke were invited to participate, and 250 patients with stroke completed questionnaires validly.
Questionnaires were administered offline to collect data, consisting of four parts: general demographics and scales related to recurrence risk perception, perceived social support, and health behaviour. A path analysis and correlation analysis were used to analyse the data.
Out of 250 patients with stroke, 78.4% had moderately low health behaviour. The majority (70.8%) of these patients were elderly. High recurrence risk perception and high perceived social support were significantly associated with better health behaviour (all p<0.001). Perceived social support mediated the relationship between recurrence risk perception and health behaviour after controlling for age, gender, education and monthly income in the regression model (95% CI 0.263 to 0.460) and the effect value was 0.360. It was also confirmed that perceived social support had the highest mediation effect with a proportion of mediation up to 59.31%.
Recurrence risk perception and perceived social support were influential factors in promoting health behaviour. Moreover, the impact of recurrence risk perception on health behaviour was partially mediated by perceived social support. Therefore, to enhance the sustainability of health behaviour, it is crucial to inform patients with stroke about the risk of recurrence. Patients with more perception of recurrence risk can improve their recovery confidence and thus perceive more social support.
探讨具有高复发风险感知的卒中患者是否会采取更健康的行为，以及感知到的社会支持是否起到中介作用。
横断面研究。
在中国一家公立三级医院进行。
共邀请 254 名卒中患者参与，250 名卒中患者完成了有效问卷。
线下发放问卷收集数据，内容包括：一般人口统计学信息和与复发风险感知、感知社会支持以及健康行为相关的量表。采用路径分析和相关分析进行数据分析。
在 250 名卒中患者中，78.4%的患者健康行为处于中等偏低水平。其中大部分（70.8%）患者为老年人。高复发风险感知和高感知社会支持与更好的健康行为显著相关（均 p<0.001）。在回归模型中，控制年龄、性别、教育程度和月收入后，感知社会支持在复发风险感知与健康行为之间的关系中起中介作用（95%置信区间 0.263 至 0.460），效应值为 0.360。还证实了感知社会支持具有最高的中介效应，中介比例高达 59.31%。
复发风险感知和感知社会支持是促进健康行为的影响因素。此外，复发风险感知对健康行为的影响部分通过感知社会支持来介导。因此，为了提高健康行为的可持续性，告知卒中患者复发风险至关重要。感知到更高复发风险的患者可以提高康复信心，从而感知到更多的社会支持。
