People living with overweight and obesity often experience weight-based stigmatization. Investigations of the prevalence and correlates of weight bias and evaluation of weight bias reduction interventions depend upon psychometrically-sound measurement. Our paper is the first to comprehensively evaluate the psychometric properties, use of people-first language within items, and suitability for use with various populations of available self-report measures of weight bias.
We searched five electronic databases to identify English-language self-report questionnaires of weight bias. We rated each questionnaire's psychometric properties based on initial validation reports and subsequent use, and examined item language.
Our systematic review identified 40 original self-report questionnaires. Most questionnaires were brief, demonstrated adequate internal consistency, and tapped key cognitive and affective dimensions of weight bias such as stereotypes and blaming. Current psychometric evidence is incomplete for many questionnaires, particularly with regard to the properties of test-retest reliability, sensitivity to change as well as discriminant and structural validity. Most questionnaires were developed prior to debate surrounding terminology preferences, and do not employ people-first language in the items administered to participants.
We provide information and recommendations for clinicians and researchers in selecting psychometrically sound measures of weight bias for various purposes and populations, and discuss future directions to improve measurement of this construct.
超重和肥胖人群经常遭受基于体重的污名化。对体重偏见的患病率及其相关因素的调查以及体重偏见减少干预措施的评估依赖于心理测量学上可靠的测量方法。我们的论文首次全面评估了现有自我报告式体重偏见测量方法的心理测量特性、条目中以人为本语言的使用情况以及对不同人群的适用性。
我们检索了五个电子数据库，以识别有关体重偏见的英文自我报告问卷。我们根据初始验证报告和后续使用情况对每份问卷的心理测量特性进行评分，并检查条目的语言。
我们的系统评价识别出40份原始自我报告问卷。大多数问卷简短，显示出足够的内部一致性，并涉及体重偏见的关键认知和情感维度，如刻板印象和指责。许多问卷目前的心理测量证据不完整，特别是在重测信度、对变化的敏感性以及区分效度和结构效度方面。大多数问卷是在围绕术语偏好的辩论之前编制的，并且在向参与者发放的条目中未使用以人为本的语言。
我们为临床医生和研究人员提供了信息和建议，以便他们为不同目的和人群选择心理测量学上可靠的体重偏见测量方法，并讨论了改进这一结构测量的未来方向。
