Abstract

This pilot study examined test-retest and internal consistency reliabilities of original and modified formats of the Exercise Self-efficacy Scale in college-age women. 30 completed original and modified versions of the scale. Data from both tests, administered 1 wk. apart, were analyzed using the intraclass correlation coefficient (ICC) to assess test-retest reliability and Cronbach coefficient alpha for internal consistency. Scores for both versions correlated .96. Cronbach coefficients alpha for the original scale were .96 for Time 1 and .98 for Time 2, Cronbach coefficients alpha for the revised scale were .95 for Time 1 and .98 for Time 2. Test-retest reliability and internal consistency remained consistently high for both versions of the scales within this sample. Implications for use of this scale and recommendations for research are given.
