中文摘要：

目的调查胃肠肿瘤患者手术及化疗后健康行为自我效能的现状，并分析其影响因素。方法采用问卷调查法对586例胃肠肿瘤患者进行健康行为自我效能的调查，内容为患者健康行为自我效能的水平、一般人口学资料及患者的临床资料。结果胃肠肿瘤患者术后化疗后健康行为自我效能总体得分为（71．50±16．08）分，仅132例（22％）患者得分指标大于80％。患者的营养状况、文化程度和医保力度等与其总体自我效能呈正相关（P〈0．05），患者年龄、临床分期、合并慢性疾病、造口和转移隋况等与其总体自我效能呈负相关（P〈0．05），其中造口、合并慢性疾病、营养状况和年龄等是患者健康行为自我效能最主要的预测因子。结论大部分胃肠肿瘤患者健康行为自我效能仍处于中低水平，在设计和实施临床护理的过程中，应重视提高患者的健康行为自我效能，帮助患者建立和维持良好的健康生活方式，提高患者生活质量。

英文摘要：

Objective To investigate health behavior self-efficacy among gastrointestinal cancer patients after surgery and chemotherapy, and to analyze factors that influence it. Methods A total of 586 gastrointestinal cancer patients filled out a question- naire about self-efficacy,demographic characteristics and clinical disease information. Results The overall score of health behavior self-efficacy was 71.50 ± 16.08 for patients.Only 132 （22%） patients scored over 80%.Patient nutritional status,education and medical care positively correlated with general self-efficacy（P〈0.05 ）,while age, clinical stage,chronic disease, stoma and metastasis negatively correlated with it（P〈0.05）.Stoma,chronic disease,nutritional status and age were the main predictors of self-efficacy. Condusions Health behavior self-efficacy is still at a low level in most gastrointestinal cancer patients,which should be taken into account when designing and implementing clinical care.Efforts are needed to help patients adopt and maintain a health-promoting lifestyle in order to improve their quality of life.
