Weight self-stigma is conceptualized as a multidimensional concept involving experiences of shame, self-devaluation and the perception of being discriminated against in social situations due to one's weight. It has been associated with experiential avoidance, unhealthy eating behaviors, binge eating and diminish quality-of-life (QoL). The current study aims to explore the mediation effect of weight-related experiential avoidance on the relationship between weight self-stigma and obesity-related QoL in women with and without binge eating (BE). The sample comprised 282 women with overweight or obesity, from which 100 presented BE symptoms. Sample's mean age was 44.24 years (SD = 11.30), with a mean BMI of 31.40 kg/m(2) (SD = 4.53). Participants completed a set of self-reported measures regarding BE symptoms, weight self-stigma, weight-related experiential avoidance and QoL. Results from path analysis supported the mediation of weight-related experiential avoidance on the relationship between weight self-stigma and QoL, even when controlling for BMI. The model accounted 58% of QoL variance. Furthermore, the multi-group analysis revealed that the model was not invariant for both groups. The analysis of the critical ratios showed that the path from weight-related experiential avoidance to QoL was stronger for the BE group. Also the model only explained 39% of QoL for the group without BE and 65% of QoL for the BE group. This study highlights the pervasive role of weigh self-stigma, particularly fear of being discriminated and weigh-related experiential avoidance on obesity-related quality-of-life, especially for those women with BE. Additionally, it supports that interventions should focus not only in weight loss but also in improving individual's QoL, promoting the development of adaptive emotional regulation strategies.
体重自我污名被概念化为一个多维度的概念，涉及到因体重而在社交场合感到羞耻、自我贬低和被歧视的体验。它与体验回避、不健康的饮食行为、暴食和降低生活质量（QoL）有关。本研究旨在探讨体重相关体验回避在有或没有暴食（BE）的超重或肥胖女性的体重自我污名与肥胖相关 QoL 之间的关系中的中介作用。样本包括 282 名超重或肥胖的女性，其中 100 名有 BE 症状。样本的平均年龄为 44.24 岁（SD=11.30），平均 BMI 为 31.40kg/m²（SD=4.53）。参与者完成了一系列关于 BE 症状、体重自我污名、体重相关体验回避和 QoL 的自我报告测量。路径分析的结果支持体重相关体验回避在体重自我污名与 QoL 之间的关系中的中介作用，即使在控制 BMI 的情况下也是如此。该模型解释了 QoL 方差的 58%。此外，多组分析表明，该模型对两组均不具有不变性。关键比分析表明，体重相关体验回避到 QoL 的路径在 BE 组更强。此外，该模型仅解释了无 BE 组 QoL 的 39%和 BE 组 QoL 的 65%。这项研究强调了体重自我污名的普遍作用，特别是对被歧视和体重相关体验回避的恐惧对肥胖相关生活质量的影响，特别是对那些有 BE 的女性。此外，它支持干预措施不仅应关注体重减轻，还应关注改善个体的生活质量，促进适应性情绪调节策略的发展。
