This qualitative study explored which core principles of family‐based treatment (FBT) for adolescents with anorexia nervosa (AN) are perceived as most necessary for FBT to be effective in clinical practice. Paediatric interdisciplinary teams were recruited to discuss the delivery of FBT in eating disorder programmes in Ontario, Canada (N = 6). Thematic analysis was used to analyze the data generated from focus groups. Three major themes emerged: (i) parental empowerment (PE) is the most salient principle of FBT; (ii) various adolescent, parental and family factors are viewed as interfering with or enhancing PE; (iii) a variety of clinical interventions are utilized by clinicians to cultivate and increase PE. PE is identified as essential for adolescents with AN to successfully recover. Greater focus on addressing barriers to empowering parents is needed throughout FBT. Future studies should include measurements of PE to ascertain effects on treatment outcomes. Training and supervision protocols focused on promoting PE are recommended. Practitioner points PE is the most salient principle of FBT. Strategies to enhance PE in phase 1 are imperative if there has been a long illness duration or parents experience mental health issues/burnout. Special clinical attention to individual factors is recommended: comorbid diagnoses, affect dysregulation and enduring eating disorder symptoms. Efforts to enhance parental involvement throughout the treatment is paramount to supporting adolescents to recover from AN. 针对青少年神经性厌食症的家庭为本治疗中的家长赋权的临床视角 该质性研究探索了针对青少年神经性厌食症的家庭为本治疗的哪些核心原则被认为是其在临床实践中发挥有效性的必要因素。研究召集了一队跨学科的儿科医生以讨论加拿大安大略省的六个饮食紊乱项目中家庭为本治疗的执行。对焦点小组讨论的数据通过主题分析法进行了分析, 结果呈现出三个重要主题：一、家长赋权是家庭为本治疗的最显著突出的原则；二、不同的青少年、家长和家庭相关因素被认为是起到了干扰或者加强家长赋权的效果；三、临床医师采用了不同的临床干预手段来培养和促进家长赋权。家长赋权被确认是帮助青少年从神经性厌食症中痊愈的关键因素。在家庭为本的治疗过程中, 需要更加强调如何减少实现家长赋权过程中的阻碍。未来的研究中应该纳入家长赋权的指标, 以确认其在治疗结果中起到的作用。强调提升家长赋权的培训和督导指南是值得推荐的。 对实务工作者的启示 家长赋权是家庭为本治疗的最显著突出的原则 如果病情持续时间较长或者家长经历了心理健康问题/心理耗竭, 那么在第一阶段采取策略加强家长赋权是必要的。 建议临床医师特别关注个体因素：共病诊断, 情绪失调, 以及持续的饮食紊乱症状。 在整个治疗过程中努力增强家长赋权是支持青少年从饮食紊乱中痊愈的首要之务。 关键词：临床医师；饮食紊乱；家庭为本的治疗；家长赋权；质性研究
