目的 构建适用于直肠癌预防性回肠造口术后患者的高排量健康教育效果评价指标体系，为临床护理人员评估患者健康教育效果，开展针对性的健康教育和指导提供依据。 方法 以知信行理论为指导，通过文献研究、半结构式访谈法、德尔菲法及层次分析法，确定直肠癌预防性回肠造口高排量健康教育效果评价指标体系及各指标权重。 结果 2轮专家函询的有效问卷回收率分别为75%（15/20）和87%（13/15），专家判断依据系数为0.873、0.969，专家熟悉程度为0.920、0.938，专家权威程度为0.897、0.954，2轮函询各级指标的肯德尔和谐系数分别为0.267~0.338、0.377~0.397（P<0.05）。最终构建的直肠癌预防性回肠造口高排量健康教育效果评价指标体系包括3个一级指标、13个二级指标和63个三级指标。 结论 构建的直肠癌预防性回肠造口高排量健康教育效果评价指标体系能够为临床护理人员进行全面、高效的健康教育效果评价提供参考。

Objective To establish an evaluation index system for health education among high output stoma patients with low anterior resection of rectal cancer and preventive ileostomy so as to provide reference for clinical nurses to carry out targeted health education and guidance for prophylactic ileostomy patients with high output stoma. Methods Literature review，semi-structured interviews，as well as the Delphi method and Multi-dimensional Analytic Hierarchy Process were used to establish a framework of the evaluation index system based on the theory of Knowledge-Belief-Practice and set weighted value for each evaluation index. Results The response rates of the two rounds of expert consultations was 75% and 87%，respectively. The expert authority coefficients was 0.873 and 0.969，respectively. The total Kendall harmony coefficients of the two rounds of expert consultations were 0.267-0.338 and 0.377-0.397（P<0.05）. As a result，an evaluation index system of health education was developed which comprised three first-level indexes，13 second-level indexes and 63 third-level indexes for high output stoma patients with low anterior resection of rectal cancer and preventive ileostomy. Conclusion The evaluation index system can provide evidence and a practice tool for clinical nurses in conducting a comprehensive and efficient evaluation of health education among high output stoma patients with low anterior resection of rectal cancer and preventive ileostomy.
