摘要目的 评价自制脑卒中知识测量工具的信效度,了解社区全科门诊就诊的中老年人群的脑卒中知识知晓现状.方法 编制脑卒中知识测量工具,于2017年1-7月对上海市3个区10家社区卫生服务中心全科门诊就诊的45～ 75岁患者进行调查.评估工具的信效度指标包括内容效度、内部一致性信度及分半信度,并分析受试人群的知识得分情况.结果 构建脑卒中知识测量问卷1份,共计3个维度,14个条目,大范围施测在10家社区共纳入1 750例患者,其中男709例,女1 041例,年龄(65.93±3.67)岁.总量表的标准化Cronbach'sα系数为0.742,分半相关系数为0.686(P＜0.01);内容效度示各分量表与总量表及各分量表之间均呈正相关,相关系数为0.448～ 0.728(P＜0.0).受试人群脑卒中知识总体满分率8.46％(148/1 750);其中,脑卒中早期症状相关知识维度满分率46.00％(805/1 750);脑卒中相关用药知识维度满分率54.40％(952/1750);脑卒中危险因素相关知识维度满分率17.94％(314/1 750).logistic回归分析显示,女性、文化程度高、已婚/同居的人群知识得分更高(P＜0.01).结论 开发出的脑卒中知识测量问卷在社区全科门诊中老年人群中有良好的信度和效度,可作为该人群脑卒中相关知识评价工具;受试人群得分情况并不理想,该测量工具有望为全科医生向患者提供更精准全面的诊疗策略提供信息参考.

abstractsObjective To develop a stroke knowledge instrument for middle-aged and aged people in community general outpatient clinics.Methods A stroke knowledge measurement tool was developed and the reliability and validity of the tool were evaluated.The developed measurement tool was applied for patients aged 45 to 75 years old from 10 community health service centers of three Shanghai districts,and the knowledge scores of the target population were analyzed.Results A total of three dimensions and 14 items were made up of the stroke knowledge instrument.A total of 1 750 subjects,including 709 males and 1 041 females with an average age of (65.93±3.67) years,were included in the survey.The standardized Cronbach's coefficient was 0.742,and split-half correlation coefficient was 0.686 (P＜0.01) for instrument test performance.There was a positive correlation between the sub-instrument and the overall-instrument,and the correlation coefficient was 0.448-0.728 (P＜0.01) for content validity.The full score rate of overall stroke knowledge instrument was 8.46％(148/1 750),the full score rate for disease early symptomswas 46.00％(805/1 750),that for drug-related knowledge was 54.40％(95/1 750) and that for high risk factors was 17.94％(314/1 750).Logistic regression analysis showed that females,subjects with higher education level and married/cohabitation state had higher knowledge scores (P＜0.01).Conclusions The developed stroke knowledge instrument has good reliability and validity for the middle-aged and aged population of community general outpatient clinic.The stroke knowledge levels are less satisfactory for this study population.
