Development and validation of a measure of curvy ideals internalization

Abstract

Several sociocultural female body ideals exist — thin, muscular/athletic, and, more recently, curvier ideals, which research specifically suggests are more prevalent among Black women. Two validated measures assess women’s desire for curvier bodies, but neither assess certain facets of curvy ideals (e.g., thick vs. slim-thick) separately. We developed and validated the Curvy Ideals Internalization (CII) Scale, to be used alone or alongside existing measures of appearance ideal internalization. Focus groups among racially/ethnically diverse women informed initial items. A sample of 897 White (37.1%), Black (34.2%), and biracial Black and White (28.7%) U.S. women completed the initial 37-item CII to determine factor structure, narrow the item pool, and examine validity and reliability. A separate sample (N = 366) of U.S. Black, White, and biracial women completed the CII to confirm the factor structure. The final CII has eleven items, with factors assessing thick/curvy ideal internalization and facets of slim-thick ideal internalization: thin waist and large breast size. The CII has adequate internal consistency, test-retest reliability, construct validity, and factorial validity. The CII is appropriate for use among Black, White, and biracial women to assess internalization of curvier body ideals and needs to be validated in more diverse samples.
