目的基于计划行为理论考察影响中学生吸烟行为意向的相关因素,为青少年吸烟行为干预提供理论支持。方法在四川省乐山市选取2所中学随机抽取1 303名学生进行问卷调查,采用SPSS 17.0和AMOS 18.0对数据进行统计分析。结果有吸烟经历者占被试总数的25.6%,其中男生占16.1%,女生占9.5%;初中生占10.1%,高中生占15.6%。结构方程模型分析结果显示,吸烟行为经验、知觉行为控制、态度、示范性规范能依次有效预测高中生吸烟行为意向;吸烟行为经验、态度、知觉行为控制、指令性规范能依次有效预测初中生吸烟行为意向(P值均<0.05)。结论基于计划行为理论对中学生吸烟行为意向的预测具有重要意义。
Objective To investigate the related factors that influence the intention of smoking behavior of middle school students based on the theory of planned behavior and to provide theoretical support for the intervention of smoking behavior among adolescents. Methods A total of 1 303 students were randomly selected from 2 middle schools in Leshan City, Sichuan Province for questionnaire survey. The data were analyzed by SPSS 17.0 and AMOS 18.0. The results of smoking experience accounted for 25.6% of the total number of subjects, of which 16.1% were boys and girls 9.5%; junior high school students accounted for 10.1%, 15.6% of high school students. Structural equation modeling results show that the experience of smoking behavior, the control of attitude behavior, the attitude and the model norms can in turn effectively predict the intention of smoking behavior of high school students. Smoking behavior experience, attitudes, perceptual behavior control and prescriptive norms can in turn effectively predict junior high school students’ smoking Behavioral intention (P <0.05). Conclusions Based on the theory of planned behavior, it is of great significance to predict the smoking behavior intention of middle school students.
