The 7-item Body Image Disturbance Questionnaire (BIDQ; Cash et al., 2004) assesses three facets of negative body image: body dissatisfaction, body distress (or dysphoria), and body dysfunction (or impairment). Five of the seven items have an open-ended follow-up question that allows participants to clarify their responses, which is useful in clinical contexts and mixed methods research. The BIDQ can be administered online or in-person to adolescents or adults; it is free to use. This chapter first discusses the development of the BIDQ and then provides evidence of its psychometrics. More specifically, the BIDQ has been found to have a unidimensional factor structure. Internal consistency reliability, test-retest reliability, convergent validity, discriminant validity, and predictive validity support the use of the BIDQ. Next, this chapter provides all BIDQ items along with their individualized response scales, instructions for administering the BIDQ to participants, and the scoring procedure. Logistics of use, such as how to obtain the scale, permissions, copyright, and contact information are provided for readers.
