目的编制具有较高信效度的无偿献血动机评价量表,为国内无偿献血动机研究提供量化工具。方法1)以保护动机理论为构建框架,通过文献研究、开放式讨论、焦点小组条目池评分形成量表初稿;2)随机抽取南京红十字血液中心下属5个无偿献血点开展预调查,通过项目分析、语义分析、探索性因子分析进行条目池筛选和调整,形成第1版量表;3)随机抽取江苏省6市进行二次调查,进行不同动机因子的信度检验,得到第2版量表。结果 1)第1版量表支持一阶8因子结构,累计解释变异量为49.32%;2)二次调查中,总量表(!=0.870)、消极动机(!=0.829)、积极动机(!=0.843)及压力(!=0.807)、阻力(!=0.655)、恐惧(!=0.814)、反应代价(!=0.786)、内部奖励(!=0.794)、外部奖励(!=0.613)、自我效能(!=0.774)、严重性(!=0.612)信度良好。结论本研究开发的无偿献血动机量表具有良好的信效度,可作为我国无偿献血者献血动机评价研究的工具。
Objective To develop a scale of voluntary blood donation evaluation with high reliability and reliability, and to provide a quantitative tool for the study of motivation of voluntary blood donation in China. Methods 1) Based on the theory of protection motivation, the first draft of the scoring scale was formed through literature research, open discussion and focus group entry pool; 2) 5 unofficial blood donation points were randomly selected from Nanjing Red Cross Blood Center to conduct pre-investigation. Analysis, semantic analysis, exploratory factor analysis of the entry pool screening and adjustment, the formation of the first edition of the scale; 3) randomly selected six cities in Jiangsu Province for the second survey, the reliability of different motivation factor test, the second edition table. Results 1) The first edition of the scale supported the first-order 8-factor structure and explained a total of 49.32% of variance. 2) In the second survey, the total scale (= 0.870), negative motivation ! = 0.843) and pressure (= 0.807), resistance (= 0.655), fear (= 0.814), reaction cost (= 0.786), internal reward Self-efficacy (! = 0.774), severity (! = 0.612) Good reliability. Conclusion The voluntary blood donation motivation scale developed in this study has good reliability and validity and can be used as a tool to evaluate the motivation of blood donation in our country.
