Development of stroke knowledge instrument for middle-aged and aged people in community general outpatient clinics / 中华全科医师杂志

ABSTRACT

Objective 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.
