  • The researchers acknowledge and thank the abused women survivors who participated in this study and helped us discover new knowledge that may help others. The researchers are most appreciative of the instrument development work of Drs. Varvaro and Palmer and their willingness to give us permission to develop our initial instrument based on a revision of the SESFBW. Copies of the SESAW can be obtained by contacting Dr. May.


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.
