雖然既往的研究已檢視影響健康行為的一些特定因子，至於慢性病患者其健康概念與健康行為間的交互關係則尚未有人做探討。本研究目的即在探討慢性病患者健康概念六大因素對其健康行為的個別影響力。以健康概念量表與健康行為量表訪談了372位慢性病患者。六個假設模式以最大概似法來加以檢定評估，所使用的電腦軟體為LISREL 8.3。本研究所提出模式的適當性支持健康概念的因素會影響健康行為的觀點。其中又以對生活的熱忱、安寧、與意義為影響量較大的因素。這些因素分別可解釋健康行為34-43%的變異量。本研究結果支持慢性病患者健康行為能由其健康概念來加以預估的立論。未來可採縱貫式研究設計，以進一步確定慢性病患者健康概念與其健康行為間的因果關係。

　　　　　Although previous studies have examined selected factors influencing health behavior, the complex interplay of the concept of health and health behavior in persons with chronic illness has not been investigated. The purpose of this study was to investigate the individual effects of six factors in the concept of health on the health behavior of Taiwanese people with chronic illness. A sample of 372 persons with chronic illness completed instruments measuring their concept of health and health behavior. Six proposed models were assessed using the maximum likelihood estimation, which is implemented by LISREL 8.3. The overall fit of the models tested in this study lends support to the assertion that the factors of the concept of health affect health behavior. Zest for life, serenity and meaning were the strongly affecting factors. These factors each accounted for 34-43% of the variance in health behavior. The results of this study support the notion that the health behavior of people with chronic illness can be predicted by their concept of health. Further research using a longitudinal design is needed to clarify the causal relationship between the concept of health and health behavior in Taiwanese people with chronic illness.
