This article describes the development and psychometric evaluation of the Counseling Women Competencies Scale (CWCS). The CWCS is designed to assess clinicians' self-perceived competencies with regard to therapeutic practice with diverse female clients. Through an extensive review of the literature on counseling women and expert review by 32 members of the Section for the Advancement of Women (Division 17, APA), content validity was supported. Exploratory factor analysis, conducted on a sample of 321 male and female counseling and psychology graduate students and professionals, supported a two-factor model consisting of knowledge/skills and self-awareness factors. Findings also provided support for the internal consistency reliability and construct (convergent, divergent, and incremental) validity of the scale. (Contains 3 tables.)
