The 18-item Body, Eating, and Exercise Comparison Orientation Measure (BEECOM; Fitzsimmons-Craft, Bardone-Cone, & Harney, 2012 assesses body-, eating-, and exercise-related social comparison tendencies. The BEECOM [scale abbreviation] can be administered online and in person to adults and is free to use in any setting. This chapter first discusses the development of the BEECOM and then provides evidence of its psychometrics. More specifically, the BEECOM has been found to have three-factor structure within exploratory and confirmatory factor analyses and demonstrates invariance across age, gender, and eating disorder history status. Internal consistency reliability, test-retest reliability, convergent validity, discriminant validity, and incremental validity support the use of the BEECOM. Next, this chapter provides the BEECOM items in their entirety, instructions for administering the BEECOM to participants, the item response scale, and the scoring procedure. A nine-item abbreviated form is offered, and translations are provided. Logistics of use, such as permissions, copyright, and contact information, are provided for readers.
