Body dissatisfaction is prevalent among adolescents and a primary risk factor for eating disorders, yet there are few body image interventions for older adolescents that support development of positive body image. Therefore, we assessed the feasibility, acceptability and preliminary effectiveness of BodyKind, a four-lesson, mixed gender, teacher-led, school-based curriculum for older adolescents, that combines principles of self-compassion, compassion for others, cognitive dissonance, and social activism to address contemporary adolescent body image concerns (i.e., appearance bias, comparisons on social media) and strengthen positive body image development. The sample contained 147 adolescents, predominantly racial/ethnic minorities (>95%), 54.8% male, 41.5% female and 4.1% gender-minority students aged 15–18 years (M=16.24, SD=.96) from a low-income, inner-city high school in the Midwestern US. Two teachers received training and delivered the curriculum to students. This single arm, mixed methods trial assessed student and teacher acceptability, teacher fidelity and student intervention outcomes. Despite reasonable teacher fidelity, recruitment/attendance rates, post-intervention data loss (35% attrition) limited evaluations of program effectiveness and study feasibility. Important learnings regarding study feasibility will inform optimisation for future school-based trials. Findings demonstrate high acceptability of BodyKind among teachers and adolescents in a lower socioeconomic school setting, and further randomized controlled effectiveness trials are required.

身体不满意在青少年中普遍存在，也是饮食失调的主要危险因素，但针对年龄较大的青少年，很少有身体意象干预措施能够支持积极的身体意象的发展。因此，我们评估了 BodyKind 的可行性、可接受性和初步有效性，这是一门针对年龄较大青少年的四节课、混合性别、教师主导、校本课程，结合了自我同情、同情他人、认知失调和社会行动主义，解决当代青少年身体形象问题（即外表偏见、社交媒体上的比较）并加强积极的身体形象发展。样本包含 147 名青少年，主要是少数族裔 (>95%)，其中 54.8% 为男性，41.5% 为女性，4.1% 为 15-18 岁的性别少数学生（M =16.24，SD =.96），来自低收入家庭。收入，美国中西部的市中心高中。两名教师接受了培训并向学生教授课程。这项单臂、混合方法试验评估了学生和教师的可接受性、教师的忠诚度和学生干预结果。尽管教师忠诚度合理，但招聘/出勤率、干预后数据丢失（35% 流失）限制了项目有效性和研究可行性的评估。有关研究可行性的重要知识将为未来校本试验的优化提供信息。研究结果表明，社会经济地位较低的学校环境中的教师和青少年对 BodyKind 的接受度很高，需要进一步的随机对照有效性试验。
