Weight loss is hard to achieve and even harder to maintain. Engaging in effortful behavioural change to manage body weight can sometimes result in feelings of guilt and shame. Self-compassion, the tendency to find kindness for oneself in times of struggle, may facilitate coping with the unique challenges of weight management. This study assessed whether a remotely delivered self-compassion intervention improved weight management outcomes when delivered as a supplement to an existing digital behavioural weight management programme, Weight Watchers (WW).
Using a mixed-method study design, 249 adults seeking to manage weight were randomized to either the WW programme or WW supplemented with the self-compassion for weight management intervention (SC4WM). Participants completed measures of self-compassion, eating behaviour, physical activity, body weight and emotional well-being along with potential moderators, including weight self-stigma, eating restraint, psychological coping and perceived stress at baseline, post-intervention (4 weeks) and follow-up (12 weeks).
There was no evidence that the SC4WM intervention had a significantly different effect than WW alone. Other than body weight, all outcomes improved over time in both groups. Self-compassion was slightly higher overall in the SC4WM group (p = .05), with this group reporting higher self-kindness at 4 weeks (p = .014) and lower self-judgement at 12 weeks (p = .023) compared to the control group.
Although the SC4WM intervention group did show a small increase in self-kindness and reduction in self-judgement, weight management outcomes were not improved over and above the existing WW programme. Recommendations for adapting the SC4WM intervention to improve efficacy to augment weight management outcomes are provided.
减肥很难实现，维持体重更是难上加难。努力进行行为改变来控制体重有时会导致内疚和羞耻感。自我同情，即在困难时期善待自己的倾向，可能有助于应对体重管理的独特挑战。本研究评估了作为现有数字行为体重管理计划“慧俪轻体”（WW）的补充，远程提供的自我同情干预是否能改善体重管理结果。
采用混合方法研究设计，将249名寻求控制体重的成年人随机分为WW计划组或补充了体重管理自我同情干预（SC4WM）的WW组。参与者在基线、干预后（4周）和随访（12周）时完成了自我同情、饮食行为、身体活动、体重和情绪健康的测量，以及潜在的调节因素，包括体重自我污名、饮食克制、心理应对和感知压力。
没有证据表明SC4WM干预与单独的WW有显著不同的效果。除体重外，两组的所有结果都随时间有所改善。SC4WM组的自我同情总体略高（p = 0.05），与对照组相比，该组在4周时报告的自我友善度更高（p = 0.014），在12周时自我评判更低（p = 0.023）。
尽管SC4WM干预组确实显示出自我友善度略有提高，自我评判有所降低，但体重管理结果并未比现有的WW计划有更大改善。提供了调整SC4WM干预以提高疗效以增强体重管理结果的建议。
