The development of a new measure of concussion knowledge and attitudes that is more comprehensive and psychometrically sound than previous measures is described. A group of high-school students (N = 529) completed the measure. The measure demonstrated fair to satisfactory test-retest reliability (knowledge items, r = .67; attitude items, r = .79). Exploratory factor analysis of the attitude items revealed a four-factor solution (eigenvalues ranged from 1.07-3.35) that displayed adequate internal consistency (Cohen's alpha range = .59-.72). Cluster analysis of the knowledge items resulted in a three-cluster solution distributed according to their level of difficulty. The potential uses for the measure are described.
描述了一种新的 concussion 知识和态度测量方法的开发,该方法比以前的测量方法更全面,具有更好的心理测量学特性。一组高中生(N=529)完成了该测量。该测量方法表现出了良好的重测信度(知识项目,r=0.67;态度项目,r=0.79)。对态度项目的探索性因素分析显示了一个四因素解决方案(特征值范围为 1.07-3.35),具有足够的内部一致性(Cohen's alpha 范围为 0.59-0.72)。知识项目的聚类分析产生了根据其难度分布的三聚类解决方案。描述了该测量方法的潜在用途。
