目的:验证基于信息—动机—行为（IMB）模型的健康教育在溃疡性结肠炎患者中的应用效果。方法:采用便利抽样法，选取2019年3月—2020年3月无锡市第二人民医院消化内科收治的83例溃疡性结肠炎患者为研究对象，按照随机数字表法分为试验组（42例）和对照组（41例）。对照组接受常规护理，试验组在常规护理的基础上接受基于IMB模型的健康教育。研究结束后，对照组因病情退出2例，试验组失访3例。最终纳入对照组和试验组患者各39例。比较两组患者的用药依从性、疾病活动程度、疾病不确定感、生活质量得分。结果:出院时、出院后1周、出院后1个月试验组的用药依从性得分高于对照组，疾病活动程度得分低于对照组，差异有统计学意义（n P<0.01）。干预后，试验组患者疾病不确定感得分低于对照组，生活质量得分高于对照组，差异均有统计学意义（n P<0.01）。n 结论:基于IMB模型的健康教育可以提升溃疡性结肠炎患者的治疗依从性，降低其疾病活动度和疾病不确定感，提高其生活质量。“,”Objective:To verify the effectiveness of information-motivation-behavior model (IMB) -based health education in patients with ulcerative colitis.Methods:A total of 83 patients with ulcerative colitis admitted to the Department of Gastroenterology in Wuxi Second People's Hospital from March 2019 to March 2020 were selected as the study subjects, and they were divided into an experimental group (n n=42) and a control group (n n=41) according to the random number table method. The control group received routine nursing care, while the experimental group received health education based on the IMB model besides routine nursing care. After the end of the study, 2 patients in the control group withdrew due to illness, and 3 patients in the experimental group were lost to follow-up. Finally, 39 patients in the control group and 39 patients in the experimental group were included. The scores of medication compliance, disease activity, disease uncertainty and quality of life were compared between the two groups.n Results:At the time of discharge, one week after discharge and one month after discharge, the scores of medication compliance in the experimental group were higher than those in the control group, and the scores of disease activity in the experimental group were lower than those in the control group. The differences were statistically significant (n P<0.01) . After the intervention, the score of disease uncertainty in the experimental group was lower than that in the control group, and the score of quality of life in the experimental group was higher than that in the control group, and the differences were statistically significant (n P<0.01) .n Conclusions:Health education based on the IMB model can improve the treatment compliance of ulcerative colitis patients, reduce the disease activity and disease uncertainty, and improve the quality of life.
