The 11-item Body Image Ideals Questionnaire (BIQ; Cash & Szymanski, 1995) approaches the assessment of evaluative body image by considering both appearance evaluation and importance within its structure. Each item has two parts: first respondents evaluate an aspect of their body (appearance, functionality) and then rate how important that specific aspect is to them. The BIQ can be administered online or in-person to adolescents or adults; it is free to use. This chapter first discusses the development of the BIQ and then provides evidence of its psychometrics. More specifically, the BIQ has been found to have a 2-factor structure: Discrepancy (from body ideal) and Importance (of ideal to body image). Internal consistency reliability and convergent validity support the use of the BIQ, and the BIQ is responsive to therapeutic intervention. Next, this chapter provides all items and the response scales for both Discrepancy and Importance, instructions for administering the BIQ to participants, and scoring procedures. Logistics of use, such as how to obtain the scale, permissions, copyright, and contact information are provided for readers.
