The Fat Acceptance Scale: Development and initial validation.

The fat acceptance movement arose to combat the widespread stigmatization of fatness and fat people through personal liberation and political activism. Support for the movement and its underlying ideology has grown rapidly over the past three decades; however, a self-report measure of fat acceptance with strong psychometric properties has not yet been developed. The current studies aimed to develop the Fat Acceptance Scale (FAS), a measure of fat-accepting beliefs, attitudes, and behaviors that was designed to be appropriate for use with people of all sizes. In Study 1, exploratory factor analysis ( = 266) and confirmatory factor analysis ( = 267) supported a three-factor solution assessing fat activism, health beliefs related to weight, and interpersonal respect for fat individuals. In Study 2 ( = 291), FAS scores predicted reactions to fictitious fat women after controlling for an established measure of antifat attitudes. Data from a subsample of 47 participants indicated moderate-to-high stability of the FAS over 4 weeks. In Study 3 ( = 156), health service psychology doctoral students' FAS scores predicted their reactions to a fictional fat psychotherapy client after controlling for antifat attitudes. Taken together, results provided preliminary evidence for the validity and reliability of FAS scores and suggest that the FAS may be a valuable tool for researchers, clinicians, and advocates interested in fat acceptance.
