菸害衛教是防治菸害最常見介入措施，針對衛教內容進行評值，可瞭解衛教成效。本研究目的為發展與測試菸害健康認知量表；第一階段為建構菸害健康認知量表並檢定內容效度。第二階段針對未吸菸者及吸菸者施測，並進行探索性因素分析以檢定量表效度。本研究通過北部某區域醫院倫理審查委員會核可，經方便取樣，針對該院內外科住院病人進行調查，共140 位未吸菸者及249 位吸菸者完成問卷。菸害健康認知量表共計22 題。以未吸菸者資料萃取出三個因素，分別是生理認知- 記憶性、理解性及心理認知，可解釋總變異量為52.13%。而吸菸者資料萃取出四因素，分別是生理認知- 記憶性、理解性、應用性及心理認知，可解釋總變異量為50.87%。菸害健康認知量表可適用於評量未吸菸者與吸菸者之菸害衛教後之菸害認知。其中生理認知次量表歸類因素不盡相同，但可區辨未吸菸者及吸菸者間之認知差異性，以作為菸害防治工作之參考。

Health education regarding the harms of tobacco use is essential for preventing tobacco-related health problems. The health education content of a test was analyzed to establish the results and effectiveness of health education. The aim of this study was to develop a tobacco harm to health cognitive scale (THHCS). In the first phase of the construction of the THHCS, the content validity was tested. The second phase involved nonsmokers and smokers being administered the test. Exploratory factor analysis (EFA) was applied to detect the validity of the scale. This study was approved by the ethics institutional review board of the study hospital. Convenience sampling was used. A total of 140 nonsmoking and 249 smoking inpatients completed the questionnaire in the medical and surgical wards of the study hospital. The THHCS comprised 22 questions. The EFA of nonsmokers involved extracting three factors, namely physiological cognition, memory/ comprehension, and psychological cognition; the total explanatory variation was 52.13%. The EFA of smokers involved extracting four factors, namely physiological cognition, memory/ comprehension/application, and psychological cognition; the total explanatory variation was 50.87%. The THHCS can be applied to both nonsmokers and smokers after tobacco harm education for tobacco harm prevention. ＂Physiological perception＂ had different subscales for nonsmokers and smokers; therefore, the scoring scale required consideration of whether users were nonsmokers or smokers.
