摘要:
目的 应用格林模式中三大因素与行为进行相关性分析,以便了解马鞍山市常住居民阿尔茨海默病(alzheimer's disease,AD)的相关行为,探索三大因素对AD有关行为的影响。 方法 采用问卷调查法,以滚雪球抽样法进行问卷发放,合计回收有效问卷761份。数据分析采用SPSS 21.0软件,其中倾向因素与行为分析采用AMOS 21.0建模,利用结构方程模型(structural equation model,SEM)分析相关性;促成因素、强化因素与行为之间采用Spearman和Pearson相关性分析。 结果 倾向因素中态度对行为的总体影响为0.562,知识对行为的间接影响为0.243;促成因素中医疗质量(r=-0.073,P=0.045)、开展分级诊疗(r=0.146,P < 0.001)、制定老年疾病相关政策(r=0.099,P=0.006),三者均与行为有相关性。强化因素中自我健康评估(r=0.110,P=0.002)、通过组织健康传播(r=0.191,P=0.035)或大众健康传播(r=0.115,P=0.011)渠道获得AD相关信息的频率,以及人际健康传播(r=0.274,P < 0.001)或组织健康传播(r=0.177,P < 0.001)中对老年健康议题的传播频率,五者与行为的关系均呈正相关。 结论 通过健康传播途径提高阿尔茨海默病与老年健康相关知识的传播、促进当地医疗条件的改善,以及开展分级诊疗并制定与老年疾病相关的政策,有助于促进受众对阿尔茨海默病持以正向的行为。 Abstract:Objective In order to study the behaviors of Ma'anshan residents on alzheimer's disease (AD), by using the three factors of PRECEDE-PROCEED model, this paper analyzed their correlation with behaviors, explored the influence of three factors on AD related behavior. Methods The study used snowball sampling method to conduct questionnaire survey, 761 valid questionnaires were collected in total. SPSS 21.0 software was applied to analyze the data, and AMOS 21.0 modeling was used to analyse the predisposing factors and behaviors, structural equation model (SEM) was used to analyze the correlation. Spearman and Pearson were used to analyze the relativity among enabling factors, reinforcing factors and the behaviors. Results It was found that about predisposing factors, attitude affected behavior with a general influence coefficient of 0.562, and knowledge had an indirect effect on behavior with an influence coefficient of 0.243. Among the enabling factors, medical quality (r=-0.073, P=0.045), hierarchical medical treatment (r=0.146, P < 0.001) and policy support on elderly diseases (r=0.099, P=0.006) were all correlated with behaviors. The self-health assessment (r=0.110, P=0.002) of reinforcing factors, the frequency of obtaining AD related information through organization health communication (r=0.191, P=0.035) or mass health communication (r=0.115, P=0.011) channels and the frequency of elderly health issue transmission in interpersonal health communication (r=0.274, P < 0.001) or organization health communication (r=0.177, P < 0.001), which were positively correlated with behaviors. Conclusions It is conducive to promote people's positive behaviors toward AD through health communication sharing on AD and other elderly diseases, the improvement of local medical conditions, the implementation of hierarchical medical treatment and the formulation of relevant policies of elderly diseases. -
