The 14-item Self-Objectification Beliefs and Behaviors Scale (SOBBS; Lindner & Tantleff-Dunn, 2017) assesses the extent to which individuals view themselves from the perspective of a sexually objectifying observer and treat their body as capable of representing their identity. The SOBBS can be administered online or in-person to adolescents and adults and is free to use in any setting. This chapter first discusses the development of the SOBBS and then provides evidence of its psychometrics. More specifically, the Self-Objectification Beliefs and Behaviors Scale has been found to have a two-factor structure within exploratory and confirmatory factor analyses, with evidence of measurement invariance across gender and between binary transgender and non-binary individuals. Internal consistency reliability, test-retest reliability, convergent validity, discriminant validity, and incremental validity support the use of the SOBBS. Next, this chapter provides the SOBBS items in their entirety, instructions for administering the SOBBS to participants, the item response scale, and the scoring procedure.
