Obesity is a growing epidemic. Weight control interventions can achieve weight loss, but most is regained over time. Stigma and low quality of life are significant problems that are rarely targeted.
A new model aimed at reducing avoidant behavior and increasing psychological flexibility, has shown to be relevant in the treatment of other chronic health problems and is worth examining for improving the lives of obese persons.
Patients who had completed at least 6 months of a weight loss program (N = 84) were randomly assigned to receive a 1-day, mindfulness and acceptance-based workshop targeting obesity-related stigma and psychological distress or be placed on a waiting list.
At a 3-month follow-up, workshop participants showed greater improvements in obesity-related stigma, quality of life, psychological distress, and body mass, as well as improvements in distress tolerance, and both general and weight-specific acceptance and psychological flexibility. Effects on distress, stigma, and quality of life were above and beyond the effects due to improved weight control. Mediational analyses indicated that changes in weight-specific acceptance coping and psychological flexibility mediated changes in outcomes.
Results provide preliminary support for the role of acceptance and mindfulness in improving the quality of life of obese individuals while simultaneously augmenting their weight control efforts.
肥胖问题日益严重。体重控制干预措施能够实现体重减轻，但随着时间推移，大部分体重会反弹。耻辱感和低生活质量是严重问题，却很少得到关注。
一种旨在减少回避行为并增强心理灵活性的新模式，已被证明与其他慢性健康问题的治疗相关，值得研究以改善肥胖者的生活。
完成至少6个月减肥计划的患者（N = 84）被随机分配，一组参加为期1天、以正念和接纳为基础、针对肥胖相关耻辱感和心理困扰的工作坊，另一组则被列入等待名单。
在3个月的随访中，参加工作坊的参与者在肥胖相关耻辱感、生活质量、心理困扰和体重方面有更大改善，在痛苦耐受力、总体及体重特异性接纳和心理灵活性方面也有改善。对困扰、耻辱感和生活质量的影响超出了因体重控制改善所带来的影响。中介分析表明，体重特异性接纳应对和心理灵活性的变化介导了结果的变化。
研究结果为接纳和正念在改善肥胖个体生活质量同时增强其体重控制努力方面的作用提供了初步支持。
