Internalized weight stigma (IWS) is highly prevalent and associated with deleterious mental and physical health outcomes. Initiatives are needed to address IWS and promote effective coping and resilience among individuals who are exposed to weight stigma. We conducted a systematic review of psychological interventions for IWS and examined their feasibility, acceptability, and preliminary efficacy at reducing IWS and related negative physiological and psychological health outcomes.
Eight databases were searched. Inclusion criteria included: (1) psychological intervention; (2) published in English; and (3) included internalized weight stigma as an outcome. Exclusion criteria included: (1) commentary or review; and (2) not a psychological intervention. A systematic narrative review framework was used to synthesize results.
Of 161 articles screened, 20 were included. Included interventions demonstrated high feasibility, acceptability, and engagement overall. Sixteen of 20 included studies observed significant reductions in IWS that were maintained over follow-up periods, yet data on whether interventions produced greater reductions than control conditions were mixed. Studies observed significant improvements in numerous physical and mental health outcomes.
Findings indicate that existing interventions are feasible, acceptable, and may provide meaningful improvements in IWS and associated health outcomes, highlighting the potential for psychological interventions to promote improved health and wellbeing in individuals with IWS. Additional research using rigorous study designs (e.g., randomized controlled trials) is needed to further evaluate the efficacy of interventions for IWS.
内化的体重歧视（IWS）非常普遍，且与有害的身心健康结果相关。需要采取措施来应对IWS，并促进遭受体重歧视的个体有效应对及恢复适应力。我们对针对IWS的心理干预措施进行了系统综述，并考察了它们在降低IWS以及相关负面生理和心理健康结果方面的可行性、可接受性和初步疗效。
检索了八个数据库。纳入标准包括：（1）心理干预；（2）以英文发表；（3）将内化的体重歧视作为一项结果。排除标准包括：（1）评论或综述；（2）非心理干预。采用系统的叙述性综述框架来综合结果。
在筛选的161篇文章中，纳入了20篇。纳入的干预措施总体上显示出较高的可行性、可接受性和参与度。20项纳入研究中有16项观察到IWS显著降低，且在随访期间保持稳定，但关于干预措施是否比对照条件产生更大降幅的数据参差不齐。研究观察到许多身心健康结果有显著改善。
研究结果表明，现有干预措施是可行的、可接受的，并且可能在IWS及相关健康结果方面带来有意义的改善，这凸显了心理干预在促进IWS个体健康和幸福方面的潜力。需要使用严格的研究设计（如随机对照试验）进行更多研究，以进一步评估针对IWS的干预措施的疗效。
