Examining the Stability of the 7-Item Social Physique Anxiety Scale Using a Test-Retest Method

Abstract

This study examined the stability of the 7-item Social Physique Anxiety Scale (SPAS-7) using a test-retest method. Collegiate, undergraduate (N = 201) students completed two administrations of the SPAS-7, with a 14-day separation between the administrations. The scale was administered either at the beginning or end of the physical activity class. The intraclass correlation coefficient (one-way analysis of variance) for two administrations of the SPAS-7 was R = .94 (95% confidence interval [CI]= .93 to .96). For a single administration, the intraclass correlation coefficient was R = .89 (95% CI = .86 to .92). The results revealed the SPAS-7 to be a stable tool for measuring social physique anxiety among college students.
