体重自卑对生活质量和健康行为的有害影响已经得到了充分的证实。然而，导致这些负面结果的过程却鲜为人知。心理僵化被定义为一种僵化的心理反应模式，支配着价值观和有意义的行动。缺乏有价值的行动的特点是缺乏与个人有意义的活动相关的活动。在第二次分析中，我们的目的是通过检验心理不灵活、经验回避和缺乏有价值的行动这两个子过程来扩展研究，作为体重自我污名与生活质量/健康行为结果之间关系的统计中介。分析了一项临床试验的基线数据，该试验比较了194名超重或肥胖并寻求治疗的成年人的减肥维持干预措施。结果表明，较大的经验回避和较低的行动价值与较低的生活质量和对社会角色的满意度显著相关，以及较大的抑郁、焦虑和暴饮暴食。此外，来自平行中介分析的结果表明，体重自我污名通过与经验回避和缺乏有价值的行动的关系间接地与焦虑、无节制饮食和饥饿有关。
Harmful effects of weight self-stigma on quality of life and health behaviors have been well-established. However, the processes that lead to these negative outcomes are less understood. Psychological inflexibility is defined as a pattern of rigid psychological reactions dominating over values and meaningful actions. A lack in valued action is characterized by the absence of activities that are connected to what is personally meaningful. In this secondary analysis, we aim to extend research by examining two subprocesses of psychological inflexibility, experiential avoidance and lack of valued action, as statistical mediators of the relations between weight self-stigma and quality of life/health behavior outcomes. Baseline data from a clinical trial comparing weight loss maintenance interventions in a sample of 194 adults living with overweight or obesity and seeking treatment is analyzed. Results show that greater experiential avoidance and lower valued action were significantly related to lower quality of life and satisfaction with social roles, as well as greater depression, anxiety, and binge eating. Further, results from a parallel mediation analysis indicated that weight self-stigma is indirectly related to anxiety, disinhibited eating, and hunger through the relationship with experiential avoidance and lack of valued action.
