The development of a scale to measure an abused woman's self‐efficacy is described. The Self‐Efficacy Scale for Abused Women (SESAW) originally was a 27‐item 100‐mm visual analog scale. It underwent face and content validity testing and was administered to a community sample of abused women ( N = 50). The SESAW was tested for internal consistency, test–retest reliability, and construct validity. Cronbach's alphas were .95 and .96 at times 1 and 2, respectively. The bivariate correlation between the SESAW at times 1 and 2 was r = .85, p < .01. Construct validity was established by a moderate bivariate correlation with the criterion as measured by the Self‐Efficacy Scale—general/global subscale ( r = .64, p < .01 at time 1, and r = .78, p < .01 at time 2). The SESAW was streamlined to 19 items. The SESAW is an acceptable measure of situation‐specific self‐efficacy in community‐based abused women. © 2004 Wiley Periodicals, Inc.
