Individuals with higher weight (overweight or obesity) may experience social stigma due to their weight. Weight stigma can be internalized with adverse health effects. Internalized weight stigma is relevant across different weight categories, but no validated weight-neutral measure of internalized weight bias currently exists in Norway. The current study aimed to examine the validity of a Norwegian translation of the Modified Weight Bias Internalization Scale.
A Norwegian translation of the Modified Weight Bias Internalization Scale (WBIS-M) was administered in an adult Norwegian sample (N = 315, of which 251 women) ranging from self-reported "very underweight" to "very overweight".
A confirmatory factor analysis was conducted on 11 of the original 11 items in the WBIS-M. Based on previous factor analyses with this scale, we expected a one-factor model. One of the items related to competence showed poor model fit, and concern was raised around possible item ambiguity partway through the study. Two versions of this item were therefore tested, neither of which yielded an acceptable fit. After exclusion of this item, the results showed high loadings for the remaining 10 items on one factor with a high internal consistency (α = 0.94). Convergent validity was approached by looking at the relationship between answers on the WBIS-M, self-perceived weight, and items on overall health and psychological/emotional state.
The 10-item Norwegian version of the WBIS-M shows sound psychometric properties and can be used to measure internalized weight bias in a weight-neutral fashion in a Norwegian-speaking population. Internalized weight bias was correlated with psychological/emotional state and overall health, with those reporting more internalized weight bias also reporting that they felt worse. This relationship was stronger for women than men in our sample and was partially dependent on weight. The women also showed higher internalized weight bias than the men. Future studies should include more male participants and explore alternative versions of the missing item related to competence.
体重较高（超重或肥胖）的个体可能因其体重而遭受社会耻辱。体重耻辱感可能会内化并对健康产生不利影响。内化的体重耻辱感在不同体重类别中都存在，但挪威目前尚无经过验证的衡量内化体重偏见的无体重差异量表。本研究旨在检验挪威语版改良体重偏见内化量表的有效性。
对改良体重偏见内化量表（WBIS-M）进行挪威语翻译，并施测于一个成年挪威样本（N = 315，其中251名女性），样本的自我报告体重范围从“非常体重过轻”到“非常超重”。
对WBIS-M原有的11个项目中的11项进行了验证性因素分析。基于此前使用该量表进行的因素分析，我们预期为单因素模型。其中一个与能力相关的项目显示出较差的模型拟合度，且在研究过程中，人们对该项目可能存在的歧义表示担忧。因此对该项目的两个版本进行了测试，但均未得到可接受的拟合度。排除该项目后，结果显示其余10个项目在一个因素上有较高的负荷，且内部一致性较高（α = 0.94）。通过考察WBIS-M的回答、自我感知体重以及总体健康和心理/情绪状态项目之间的关系来探讨收敛效度。
WBIS-M的10项挪威语版本显示出良好的心理测量学特性，可用于以无体重差异的方式测量挪威语人群的内化体重偏见。内化的体重偏见与心理/情绪状态和总体健康相关，报告有更多内化体重偏见的人也表示感觉更差。在我们的样本中，这种关系在女性中比在男性中更强，且部分取决于体重。女性的内化体重偏见也高于男性。未来的研究应纳入更多男性参与者，并探索与能力相关的缺失项目的替代版本。
