The Centers for Disease Control have suggested that physical education plays a role in promoting healthy lifestyles. Prior research suggests a link between attitudes toward physical education and physical activity outside school. The current study provides additional evidence of construct validity through a validation across two instruments measuring attitudes toward physical education by investigating their psychometric properties with a sample of 6th grade students (N = 377). Confirmatory factor analysis results indicate that the four-factor model fit the data well for both instruments based on fit indices, and a multitrait-multimethod analysis provides evidence of convergent and discriminant validity. Cross validation of these instruments permits longitudinal investigations on the role of attitudes toward physical education and their impact on physical activity.
