Metabolic syndrome is a cluster of medical disorders that increase the risk of developing cardiovascular disease. From the perspective of disease prevention, individuals with metabolic syndrome need to engage in exercise, eat a healthy diet, relieve stress, and quit smoking to reduce the incidences of cardiovascular disease. As no such questionnaire is available, so we aimed to design a questionnaire (10 items) to quantify the knowledge of metabolic syndrome prevention. People who participated to the health screening examination at Taoyuan and graduate school students (nursing, physical therapy, occupational therapy) were invited to fill out the questionnaire. Validity (including expert validity, known-group difference of construct validity, hypothesis testing of construct validity) and reliability (including internal consistence, test-retest reliability) were assessed. After developing the questionnaire, the content was rated by six experts, resulting in a mean content validity index (CVI) of 98.1%. The overall percentage of correctness reached statistical significance between participants who attended a health screening examination (n=48, 44.2%) and graduate students (n=40, 64.3%) (p<.0001), indicating our questionnaire has a satisfactory known-group difference of construct validity. In regards to hypothesis testing of construct validity, the overall percentage of correctness was significantly higher after education (95.8%) than before education (64.3%) among 40 graduate students (p<.0001). The Cronbach’s was 0.69 (n=88), indicating acceptable internal consistency. In a two-week period, 40 graduate students filled out the questionnaire twice and a Pearson correlation coefficient of 0.56 (p=.0002) was achieved, indicating a good test-retest reliability. Our questionnaire has an acceptable psychometric property, including good content validity, construct validity, internal consistency, and test-retest reliability. We welcome other researchers to use our questionnaire to survey the knowledge of metabolic syndrome prevention for other populations so that findings can be compared on the same basis. |
