The Perceived Effects of Media Exposure Scale (PEMES) assesses people’s beliefs about how their body image was impacted by exposure to specific media images (Frederick et al., 2017). It has been administered in experiments where participants are exposed to images of fashion models versus control images, and participants report whether the images had negative, neutral, or positive impacts on their feelings about different aspects of their appearance. It is was inspired by two previous scales that ask participants to assess the impact of pornography (Hald & Malamuth, 2008) and their body images (Body Image Quality of Life Inventory; Cash et al., 2004) on different aspects of their lives. The PEMES can be administered to adolescents and/or adults and is free to use. This chapter describes the development and psychometrics of the PEMES. The PEMES has been found to have a two-factor structure within two exploratory factor analyses: The PEMES-Weight subscale and PEMES-Face subscales. Internal reliability was high for both subscales. The chapter provides the PEMES items, responses scale, and scoring procedure. Logistics of use, such as permissions, copyright, and contact information, are provided for readers.
