代謝症候群是心血管危險因子的聚集現象。從預防疾病的角度，可採用運動、健康飲食、適當壓力舒解、戒菸等來改善代謝症候群，以降低引發心血管疾病的發生。因目前尚未有合適的代謝症候群防治知識量表，我們擬定一份共10題的代謝症候群防治知識量表，並進行信效度測試。對桃園地區整合性篩檢(以下簡稱整篩)的民眾及桃園地區仍在學的研究生(護研所、復科所、臨行所，以下統稱研究生)，詢問代謝症候群防治知識，並提供衛生教育的宣導。採專家效度、已知團體差異的建構效度、假說驗證的建構效度、內在一致性及再測信度等方式評估量表的信效度。結果有6位專家對此量表評分，CVI=98.1%。整體答對率是整篩民眾(48位，44.2%)低於研究生(40位，64.3%)，且達統計顯著意義(p＜.0001)，表示具已知團體差異的建構效度。研究生在衛教後(後測)的整體答對率為(95.8%)明顯高於衛教前(64.3%)，表示具假說驗證的建構效度(p＜.0001)。整篩民眾及研究生填寫量表的Cronbach's α=0.69(n=88)，表示具有不錯的內在一致性。研究生在兩週內兩次整體答對率的相關係數r值為0.56，且達統計顯著意義(p=.0002)，表示具良好的再測信度。此份代謝症候群防治知識量表具良好的信效度，歡迎廣為運用於其他研究，以求進一步比較。

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 was 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 a 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.
