Abstract
The purpose of the present study was to provide further evidence for the factor structure and composition of the Sport Anxiety Scale (SAS; Smith, Smoll, & Schutz, 1990) using a sample of competitive male rugby players (N = 570). Three models were tested using both confirmatory factor analytic and polyto-mous item-response theory procedures: Smith et al’s original model; Dunn et al.’s (2000) alternative model in which Items 14 and 20 were originally designed to measure Concentration Disruption load on the Worry factor (Model A); and Model B (the removal of Item 1). Results showed that Models A and B provided similar fits to the data. Overall these findings argue for the utilization of Model B to improve model fit and maintain conceptual clarity. Our findings suggest that the factor structure and composition of the SAS needs further examination and possible refinement before researchers can feel more confident about the effectiveness of the instrument’s psychometric properties.
