民族地区中小学教师政治信任量表编制研究

A study on the construction of political trust scale in primary and secondary school teachers in minority areas

利用项目反应理论(IRT)编制政治信任量表.方法:根据层面理论的映射语句技术制定25个项目,项目是5级计分,被试474名.结果:选取测量误差SEE小于0.5水平的l4个项目组成量表;项目区分度在[0.46,2.09]之间,符合理论标准;项目位置参数在[-3.89,3.65]之间,符合理论标准;各分量表内部一致性系数大于0.7;运用最小空间分析和结构方程进行结构验证,拟合良好.结论:编制的政治信任量表达到预期的目的并符合理论标准,项目反应理论和层面理论在量表编制中具有较好的可行性.

The scale on political trust constructed in this paper is based on the item response theory. In the paper there are mainly three parts. Firstly, researching methodology： this paper includes 474 participants as sample and 25 items, 5 levels scored, on the basis of mapping sentence in the facet theory. Secondly, the results： 14 items are selected to construct the scale on the level of error of measurement smaller than 0.5; meeting the criteria, the discriminability is [0.46-2.09], and the location parameter of item is [-3.89-3.65]; the Cronbach＇s a is greater than 0.7; in addition, its goodness of fit is fine after being verified with the smallest space analysis and structural equation modeling. Thirdly, the conclusion： the expected aims are achieved in the scale, according to theoretical requirements, and a good feasibility is assessed in the item response theory and facet theory in constructing the scale.
