Cognitive dissonance-based interventions (CDIs) have been well established as effective programs for the prevention of eating disorders. However, limited research has qualitatively explored adolescent girls experience of such interventions. The present study examined the acceptability of a cognitive dissonance-based body image intervention among adolescent girls in UK secondary schools. Adolescent girls aged 14–18 years (N = 99; M_age = 14.87, SD = 0.97) who opted to participate in the intervention were invited to provide intervention feedback via open-ended questions and small focus groups. The findings suggest that the intervention was largely acceptable among adolescent girls. Peers played an important role. Despite initial concerns about sharing within the group, the groups provided a sense of belonging and participants no longer felt alone in their experience of body dissatisfaction. Participants discussed a transition from negative to positive body image following the intervention. Although acceptability was generally high, the data provides some interesting insights into potential considerations and modifications which may be advantageous in future CDIs. These include enhancing authenticity through reduced reliance on the script, inclusion of more personal content from the peer-leaders, and more interactive activities and physical movement.

基于认知失调的干预措施 (CDI) 已被公认为预防饮食失调的有效计划。然而，有限的研究定性地探讨了青春期女孩对此类干预的体验。本研究调查了英国中学少女对基于认知失调的身体意象干预的可接受性。14-18 岁少女（N = 99；M_年龄= 14.87，SD = 0.97) 选择参与干预的人被邀请通过开放式问题和小型焦点小组提供干预反馈。研究结果表明，青春期女孩在很大程度上可以接受这种干预措施。同行发挥了重要作用。尽管最初担心在小组内分享，但这些小组提供了一种归属感，参与者在对身体不满的经历中不再感到孤单。参与者讨论了干预后从消极身体形象到积极身体形象的转变。尽管可接受性普遍较高，但数据提供了一些有趣的见解，可以了解可能对未来 CDI 有利的潜在考虑因素和修改。这些包括通过减少对脚本的依赖来增强真实性，
