The Acceptance of Cosmetic Surgery Scale (ACSS; Henderson-King & Henderson-King, 2005) was developed to measure individuals’ attitudes about cosmetic surgery as a way of enhancing physical appearance. The 16-item ACSS is comprised of three subscales that assess 1) acceptance of cosmetic surgery for intrapersonal reasons (Intrapersonal), 2) acceptance of cosmetic surgery for social or career reasons (Social), and 3) the degree to which respondents would consider having cosmetic surgery to enhance their own attractiveness (Consider). This chapter briefly describes scale development and summarizes information about psychometric properties. Evidence is provided regarding its factor structure, reliability for the overall scale and each subscale, test-retest reliability, construct validity, and discriminant validity. While the ACSS was initially developed to be administered in its entirety, research focusing only on respondents’ interest in having cosmetic surgery, has relied solely on the items that comprise the Consider subscale. The scale can be administered online or in paper-and-pencil format. All items are presented in this chapter, as are the response scale and scoring instructions.
