摘要
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 reliable and valid Voluntary Blood Donation Motivation Scale and to provide an instrument for related research on motivation for blood donation. Methods 1） The scale manuscript was formed through researching literature,open discussion and focus groups based on the Protective Motivation Theory. 2） The pre-survey was conducted at five branches of Nanjing Red Cross Blood Center,which were selected randomly. Semantic,content validity analysis and explorative factor analysis（ EFA） were employed in item selection and adjustment,forming the scale in the first edition. 3） The following survey was conducted in six cities of Jiangsu Province and the data collected was used for reliability analysis of different factors,which helped to amend the scale in the second edition. Results 1） First order eight factors of the first edited scale accounted for 49. 32% of the variance in the pre-survey study. 2） The reliability of scale（ α = 0. 870）,positive motivation（ α = 0. 829）,negative motivation（ α = 0. 843）,external pressure（ α = 0. 807）,external resistance（ α =0. 655）,fear（ α = 0. 814）,response cost（ α = 0. 786）,internal rewards（ α = 0. 794）,external rewards（ α = 0. 613）,selfefficacy（ α = 0. 774）,severity（ α = 0. 612） were good in the following study. Conclusion The Voluntary Blood Donation Motivation Scale developed and revised in this study is a reliable and valid instrument,and is suitable for future research related to voluntary blood donation nationwide.
