Abstract
Background and Purpose: This study assessed the psychometric properties of a modified
self-efficacy scale—the Pregnancy-Exercise Self-Efficacy Scale (P-ESES).
Methods: Pregnant women completed the P-ESES and physical activity questionnaires (N 5 88).
Results: Internal consistency was confirmed by Cronbach’s alpha (a 5 0.838) and equal length
Spearman–Brown (a 5 8.22). Squared multiple correlation coefficients were
calculated showing 9 of 10 items with values greater than the desired .5. A nonrotated
exploratory principal components analysis confirmed the same 9 of 10 items loaded on
a single factor, accounting for 46.1% of the variance. Each item had an acceptable load
value of .40 or higher.
Conclusions: Initial testing of the P-ESES confirmed validity and
reliability with the exception of 1 item from the original measure: “Exercising without
physician approval.”
