摘要

本研究的目的為建立及驗證中西馨療信念量表。量表之初步建立經由文獻查證、質性研究、專家檢定之外，並實行二次預測；之後，以327位診斷為B型或C型肝炎的病患爲研究對象，檢測此量表之建構效度，同時效標效度，與其他建構概念的相關及內在一致性信度。結果發現以因素分析法刪除5題因素負荷低於0.4的細項後共可檢驗出二個不同的概念因子：中醫優勢信念及西醫優勢信念，其內在一致性兩者皆為0.82；對個別求醫行為的預測發現中醫優勢信念愈強的個案使用中醫中藥的頻率愈高，接受超音波及抽血檢驗肝功能的執行頻率愈低；而西醫優勢信念愈強的人，實行運動調息方式以增強體力及接受超音波檢查肝功能的頻率愈高。在與其他建構概念間的關系則發現不同的中西醫療優勢信念其肝癌預防自我效能，肝病控制信念及肝癌篩檢利益及障礙感受等皆有不同，但與自覺健康狀態則無相關。本研究的結果支持中西醫療信念量表具有一定的信度及效度，並建議此量表可用於其他急慢性或癌症病患上，以便更精準地驗證中西醫療信念與醫療行為的關係。

The Chinese-Western Medicine Beliefs (CWMB) scale is a 22 item, general purpose, medical system beliefs scale that could be adapted for the use of understanding beliefs cancerning complementary and alternative medicine and also to predict medical use behaviors. The purpose of this study is to examine the validity and reliability of the CWMB scale. The preliminary CWMB scale was established through literature reviews, a qualitative design of interviewing 30 renal failure patients about their beliefs and experiences of utilizing Chinese and Western medical system, and three experts in this area to analyze the adequacy of items in representing the hypothetical content. Three hundred and twenty seven hepatitis B or C carrier subjects who followed up their liver function in a medical center were administered the CWMB scale, Form C Health of Locus Control scales, executive liver cancer prevention efficacy scales, benefit and barrier of liver cancer prevention questionnaire, perceived health questionnaire, and liver cancer prevention behavior questionnaire to establish the factor structure of CWMB and to establish the internal reliability, concurrent validity, and predictive validity of the resultant of two subscales: belief in the superiority of Chinese medicine and belief in the superiority of western medicine. The alpha reliabilities of the subscales were found to be sufficiently consistent to be used in research as reliable indicators of Chinese and Western medicine belief. Data from hepatitis B and C carrier subjects possessed considerable concurrent validity among the two subscales and health locus of control, efficacy in executive liver cancer prevention, and perceived benefit and barrier in executive liver cancer prevention. The predictive validity of the CWMB scale also demonstrated a desirable result. The researcher of this study suggests to administer the CWMB scale to subjects with different chronic and acute diseases in order to establish a more thorough prediction of medical choice behaviors among Chinese patients.
