摘　　要：目的探讨引入计划行为理论中的相关因素,采用结构方程模型建立老年人流感疫苗接种意愿的预测指标体系。方法成都市5城区中随机抽取2个社区,每个社区抽取1个居民小区,对小区内60岁及以上老年人进行入户调查,每个居民小区调查180人。结果主观规范对老年人的接种意愿影响最大,强度为0.499;其后依次为既往接种史,强度为0.171;行为意向,强度为0.156;接种疫苗的好处,强度为0.154;接种疫苗的坏处,强度为-0.037,是负向作用;最后是预期后悔,强度为0.012。结论主观规范是影响老年人接种意愿的最重要因素,尤其是政府和医生的建议对老年人影响最大。提示政府和医疗机构应该逐步提高临床一线医护人员的认识,形成临床医学与预防医学相结合的模式,重视三级预防,从而不断提高老年人群中流感疫苗的接种率。Objective Structural equation model was adopted to establish the prediction index for influenza vaccination intentions for the elderly. Methods A total of 1800 respondents with age over 60 years old were randomly selected from 10 communities in 5 districts of Chengdu, Sichuan, China, in August 2013. Results The variables for vaccination intention and their impact strengths were as following： subjective norm （β = 0.50）, seasonal influenza vaccination history （β= 0. 171 ）, behavioral intentions （β = 0. 156）, perceived benefits of vaccination （β =0. 154）, concerned adverse effect of vaccination （β = -0. 037）, and anticipated regret （β = 0. 012）. Conclusion Subjective norm is the most important variable for vaccination intention, especially the government and doctors＇ advices, which suggest that the government and medical institutions should improve the clinical medical staffs cognition and pay attention to tertiary prevention to improve the influenza vaccination rate.
