Weight bias internalization has received considerable attention in recent years and has been associated with serious psychological and physical consequences in Westernized societies. The modified weight bias internalization scale (WBIS-M) is one of the most frequently used instruments for assessing internalized weight stigma across different body weight categories. The aim of this study was to adapt the WBIS-M for use in Spanish adult populations. The sample consisted of 678 participants from the Spanish general population recruited through the internet, 79.6% of whom were women. The scale was translated into Spanish and then backtranslated. To study the internal structure, a cross-validation analysis was carried out including both exploratory and confirmatory factor analyses to assess the scale's psychometric properties. Internal consistency was evaluated using Cronbach's alpha and McDonald's omega and a test-retest was conducted to assess one-month stability. Results confirmed that the Spanish adaptation of the WBIS-M is an 11-item unidimensional scale, like the original version and shows excellent psychometric properties. In conclusion, the Spanish WBIS-M version seems to be a robust psychometric tool for use in clinical and research settings.
近年来，体重偏见内化受到了相当多的关注，并与西化社会中严重的心理和生理后果有关。改良的体重偏见内化量表（WBIS-M）是评估不同体重类别中内化的体重耻辱感的最常用工具之一。本研究旨在将 WBIS-M 改编为适用于西班牙成年人群体的量表。样本由通过互联网招募的 678 名西班牙普通人群组成，其中 79.6%为女性。该量表被翻译成西班牙语，然后再翻译回英语。为了研究内部结构，进行了交叉验证分析，包括探索性和验证性因素分析，以评估量表的心理测量特性。内部一致性使用 Cronbach 的 alpha 和 McDonald 的 omega 进行评估，并进行了一个月的重测以评估稳定性。结果证实，WBIS-M 的西班牙语改编版是一个 11 项的单维度量表，与原始版本相似，具有优异的心理测量特性。总之，西班牙 WBIS-M 版本似乎是一种可靠的心理计量工具，可用于临床和研究环境。
