目的 探索社会参与在脑卒中患者复发风险感知与生活质量间的中介作用，为提高脑卒中患者的生活质量提供干预靶点。方法 2021年6-8月，采取便利抽样法选取河南省某三级甲等医院的住院脑卒中患者250例为研究对象，采用脑卒中复发风险感知量表、卒中专用生活质量量表（stroke specific quality of life，SS-QOL）、自主参与量表（impact on participation and autonomy questionnaire,IPA）等对其调查。 结果 脑卒中患者生活质量、脑卒中复发风险感知、社会参与得分分别为（210.18±32.86）分、（41.04±8.64）分和[4（0,16）]分，三者间呈正相关（均P＜0.05）。不同年龄、工作状态、自理程度、卒中次数的脑卒中患者,在上述得分上的差异均有统计学意义（均P＜0.05）。社会参与在脑卒中患者生活质量和复发风险感知中存在部分中介作用，中介效应为57.84%。 结论 复发风险感知不仅可直接影响生活质量，还可通过社会参与间接影响脑卒中患者生活质量水平。医务人员在帮助患者树立正确的脑卒中复发风险意识的同时，可鼓励和支持其主动进行社会参与，进而提高其生活质量水平。

Objective To explore the mediating effect of social participation on recurrence risk perception and quality of life in stroke patients, and to provide intervention for improving the quality of life in stroke patients.Methods From June to August 2021, a total of 250 stroke inpatients were selected from a tertiary A hospital in Henan province by convenience sampling method.A questionnaire survey was conducted using stroke recurrence risk perception scale, stroke specific quality of life (SS-QOL), and impact on participation and autonomy questionnaire (IPA).Results The scores of quality of life, recurrence risk perception and social participation were (210.18±32.86) points, (41.04±8.64) points and [4（0,16）] points respectively, which were positively correlated（all P＜0.05）.Stroke patients with different age, working status, self-care degree and stroke frequency had statistically significant differences in the above scores (all P＜0.05).Social participation partially mediated the quality of life and recurrence risk perception of stroke patients.The mediating effect was 57.84%.Conclusions Recurrence risk perception can indirectly affect the quality of life of stroke patients through social participation.It is suggested that while helping patients establish the correct risk awareness of stroke recurrence, medical staff can encourage and support patients to actively participate in society, so as to improve stroke patients’ quality of life.
