    We made detailed research for relationships among physical condition, self-efficacy and psychological adjustment of patients with advanced cancer in Japan. The sample consisted of 85 (41 males and 43 females) advanced cancer patients. Interviews were conducted with some measurement scales including the Self-efficacy scale for Advanced Cancer (SEAC). and the Hospital Anxiety and Depression Scale (HADS). Karnofsky Performance Status (KPS) and medication status were also recorded from the evaluation by physicians. We used structural equation modeling (SEM) for statistical analysis. The analysis revealed that the model, including three self-efficacy subscales, depression. anxiety, KPS. meal, liquid-intake. prognosis and three latent variables: 'Self-efficacy'. 'Emotional Distress'. and 'Physical Condition,' fit the data (chi-square(24) = 28.67, p = 0.23: CFI = 0.98; RMSEA = 0.05). In this model. self-efficacy accounted for 71 ' of the variance in emotional distress and physical condition accounted for of the variance in self-efficacy. Overall, our findings suggest clearly that close relationships existed among physical condition. self-efficacy and emotional distress, That is. patients in good physical condition had a high self-efficacy, and patients with high self-efficacy, ere less emotionally distressed, These results imply that psychological intervention which emphasizes self-efficacy would be effective for advanced cancer patients.
