Objective To explore the effects of trans - theoretical model - based motivational interviewing on blood glucose level and self - management behavior of elderly patients with type 2 diabetes. Methods 162 elderly patients with type 2 diabetes who were admitted to Geriatrics Department of the Third Xiangya Hospital of Central South University from January 2014 to March 2015 were divided into experimental group(80 cases)and control group(82 cases)by the random number table method. Patients in experimental group received trans - theoretical model - based motivational interviewing on the basis of routine nursing and health education,while patients in control group received routine nursing and health education. Before intervention and 6 months after intervention,levels of fasting blood glucose(FBG),glycosylated hemoglobin(HbA1c )and 2 - hour post -meal blood glucose(2 hPBG),type 2 diabetes self - management behavior scale score( the scale included 6 contents:diet control,physical exercise,take the medicine according to the instruction,blood sugar monitoring,foot care,abnormal blood sugar processing)were compared between two groups. Results There was no significant difference in levels of FBG,2 hPBG and HbA1c before intervention and level of 2 hPBG after intrvention between two groups(P > 0. 05). After intervention,levels of FBG and HbA1c of patients in experimental group were significantly lower than those of patients in control group,respectively(P< 0. 05). Before intervention,there was no significant difference in scores of diet control,physical exercise,take the medicine according to the instruction,blood sugar monitoring,foot care and abnormal blood sugar processing between two groups(P >0. 05). After intervention,scores of diet control,physical exercise,take the medicine according to the instruction,blood sugar monitoring,foot care and abnormal blood sugar processing of patients in experimental group were significantly higher those of patients in control group, respectively ( P < 0. 05 ) . Conclusion The trans - theoretical model - based motivational interviewing can help control blood glucose level and improve self - management behavior among elderly patients with type 2 diabetes.%目的：探讨基于跨理论模型的动机性访谈对老年2型糖尿病患者血糖及自我管理行为的影响。方法选取2014年1月—2015年3月在中南大学湘雅三医院老年科住院治疗的2型糖尿病患者162例，采用随机数字表法将患者分为试验组（80例）和对照组（82例）。对照组患者入院后采用常规护理和健康教育进行干预，试验组患者在常规护理和健康教育基础上采用基于跨理论模型的动机性访谈进行干预。干预前及干预后6个月，比较两组患者空腹血糖（FBG）、糖化血红蛋白（HbA1c ）、餐后两小时血糖（2 hPBG）以及2型糖尿病自我管理行为量表评分（包含饮食控制、锻炼、遵医嘱服药、血糖监测、足部护理、高低血糖处理6个方面）。结果两组患者干预前 FBG、2 hPBG、HbA1c水平及干预后2 hPBG 水平比较，差异无统计学意义（P ＞0.05）；干预后试验组患者 FBG、HbA1c 水平低于对照组（P ＜0.05）。干预前两组患者饮食控制、锻炼、遵医嘱服药、血糖监测、足部护理、高低血糖处理评分比较，差异无统计学意义（P ＞0.05）；干预后试验组患者饮食控制、锻炼、遵医嘱服药、血糖监测、足部护理、高低血糖处理评分均高于对照组（P ＜0.05）。结论基于跨理论模型的动机性访谈能帮助老年2型糖尿病患者有效控制血糖，并改善其自我管理行为。
