A Psychometric Evaluation of the Self-Presentational Efficacy Scale

This study examined the psychometric properties of the Self-Presentational Efficacy Scale (SPES) developed by Gammage, Hall, and Martin Ginis (2004 Gammage, K. L., Hall, C. R. and Martin Ginis, K. A. 2004. Self-presentation in exercise contexts: Differences between high and low frequency exercisers. Journal of Applied Social Psychology, 34: 1638–1651. Crossref], Web of Science ®] , Google Scholar]). University students (196 men and 269 women) completed the SPES and measures of social physique anxiety, fear of negative evaluation, and physical activity. Participants also completed the SPES a second time. A series of multivariate data analyses were conducted to examine the SPES's factor structure. Confirmatory factor analysis indicated a 3-factor model, with each factor representing a distinct latent variable. Acceptable internal consistency and test–retest reliability were found. Evidence of concurrent validity with respect to sex and exercise status was demonstrated. Convergent validity was also shown, as relationships to exercise participation and self-presentational anxiety were found. Future research should assess the reliability and validity of the SPES in other samples and the relative and unique contribution of the three factors in predicting exercise-related outcomes.
