Psychometric Properties of the WBIS/M in a Representative Prebariatric Sample: Evidence for an Improved 10-Item Version.

ABSTRACT:

Introduction

The Weight Bias Internalization Scale and the Modified Weight Bias Internalization Scale are well-established self-report questionnaires for assessing weight bias internalization, which is widespread among bariatric patients. However, among this group, psychometric properties of the Weight Bias Internalization Scale have only been examined in small samples showing unsatisfactory model fit and have not been explored for the modified questionnaire.

Methods

This study psychometrically evaluated and compared the Weight Bias Internalization Scale and Modified Weight Bias Internalization Scale in a large sample of prebariatric patients (N = 825, mean age = 46.75 years, SD = 11.55) regarding item characteristics, model fit to unidimensionality, reliability, construct v
