The development of a survey to examine knowledge about and attitudes toward concussion in high-school students

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.
