This study evaluated a 90-min single session school-based body image intervention (Dove Confident Me: Single Session), and investigated if delivery could be task-shifted to teachers. British adolescents (N = 1707; 11-13 years; 50.83% girls) participated in a cluster randomised controlled trial [lessons as usual control; intervention teacher-led (TL); intervention researcher-led (RL)]. Body image, risk factors, and psychosocial and disordered eating outcomes were assessed 1-week pre-intervention, immediate post-intervention, and 4-9.5 weeks follow-up. Multilevel mixed-models showed post-intervention improvements for intervention students relative to control in body esteem (TL; girls only), negative affect (TL), dietary restraint (TL; girls only), eating disorder symptoms (TL), and life engagement (TL; RL). Awareness of sociocultural pressures increased at post-intervention (TL). Effects were small-medium in size (ds 0.19-0.76) and were not maintained at follow-up. There were no significant differences between conditions at post or follow-up on body satisfaction, appearance comparisons, teasing, appearance conversations and self-esteem. The intervention had short-term benefits for girls' body image and dietary restraint, and for eating disorder symptoms and some psychosocial outcomes among girls and boys. A multi-session version of the intervention is likely to be necessary for sustained improvements. Teachers can deliver this intervention effectively with minimal training, indicating broader scale dissemination is feasible.

本研究评估了一项 90 分钟的单次学校身体意象干预（自信的鸽子：单次课程），并探讨了是否可以将其任务转移给教师。英国青少年（N=1707；11-13 岁；50.83%为女孩）参加了一项集群随机对照试验[常规课程对照；干预教师主导（TL）；干预研究人员主导（RL）]。在干预前 1 周、干预后即刻和 4-9.5 周随访时评估身体意象、风险因素以及心理社会和饮食失调结果。多层次混合模型显示，干预学生在身体自尊（TL；仅女孩）、负性情绪（TL）、饮食限制（TL；仅女孩）、饮食失调症状（TL）和生活参与度（TL；RL）方面的改善优于对照组。干预后（TL）对社会文化压力的认识增加。干预的效果为中等大小（ds 0.19-0.76），在随访时并未持续。在干预后或随访时，条件之间在身体满意度、外貌比较、嘲笑、外貌对话和自尊方面没有显著差异。该干预对女孩的身体意象和饮食限制以及女孩和男孩的饮食失调症状和一些心理社会结果有短期益处。需要多轮干预才能持续改善。经过少量培训，教师即可有效地提供这种干预，表明更广泛的推广是可行的。
