体重偏差内化（WBI）是一种基于体重的自我贬低过程，与不良的心理和身体健康有关。然而，WBI 现有的概念化和操作化存在局限性，引发了人们对该证据基础的影响的质疑。为了解决这些局限性，本研究通过对 WBI（目前已实施）和概念相关的相关性之间的关联进行荟萃分析，调查了 WBI 的构造有效性。截至 2021 年 10 月的研究已确定，这些研究为 WBI 与概念相关的构造之间的关联提供了零阶相关性。元回归确定这些关联在 WBI 指标和人口统计（年龄、性别、种族、BMI）和研究水平（发表状态、样本类型、研究质量）调节因素中是否存在差异。确定了 128 个（子）样本的数据（M 样本大小 = 477.83，SD = 1,679.90；Mage = 34.46，SD = 12.17；范围 = 10.21–56.60）。更大的 WBI 与与此结构有相当大重叠的因素（消极和积极的身体形象、自我贬低）、一般和特定体重的经验性回避以及个人对未来体重耻辱的预期表现出很大到非常大的关联。对于 WBI 概念化中差异化包含的其他结构（认可体重偏见、体重耻辱刻板印象意识、体重耻辱经历）以及通过测量相关、人口统计和研究水平因素，关联有所不同。这些发现提供了可以推进 WBI 概念化和措施细化的重要信息。
Weight bias internalization (WBI), a process of weight-based self-devaluation, has been associated with adverse mental and physical health. However, there are limitations with the existing conceptualization and operationalization of WBI that raise questions about the implications of this evidence-base. To address these limitations, the present study investigated the construct validity of WBI by conducting a meta-analysis of associations between WBI (as currently operationalized) and conceptually-related correlates. Studies identified through October 2021 that provided zero-order correlations for associations between WBI and conceptually-related constructs were examined. Meta-regression determined whether these associations differed across WBI measures and demographic (age, sex/gender, race, BMI) and study-level (publication status, sample type, study quality) moderators. Data for 128 (sub)samples were identified (Msample size=477.83, SD=1,679.90; Mage=34.46, SD=12.17; range=10.21–56.60). Greater WBI exhibited large to very large associations with factors suggested to have considerable overlap with this construct (negative and positive body image, self-devaluation), general and weight-specific experiential avoidance, and individuals’ anticipation of future weight stigma. Associations varied for other constructs that have been differentially included in conceptualizations of WBI (endorsing weight bias, weight stigma stereotype awareness, weight stigma experiences), and via measurement-related, demographic, and study-level factors. These findings provide important information that can advance WBI conceptualization and measure-refinement.
