This Randomized Controlled Trial [(RCT) aims to evaluate the effectiveness of a brief Acceptance and Commitment Therapy (ACT)-based intervention combined with treatment as usual (TAU) compared to TAU only in improving psychological conditions in a sample of adolescents with obesity (body mass index, BMI > 97th percentile for age and sex) within the context of a wider multidisciplinary rehabilitation program for weight loss. Fifty consecutive adolescents (12-17 years) of both genders with obesity will be recruited among the patients hospitalized in a clinical center for obesity rehabilitation and randomly allocated into two experimental conditions: ACT + TAU vs. TAU only. Both groups will attend a three-week in-hospital multidisciplinary rehabilitation program for weight loss. The ACT + TAU condition comprises a psychological intervention based on ACT combined with a standard psychological assessment and support to the hospitalization. The TAU comprises the standard psychological assessment and support to the hospitalization. At pre- to post-psychological intervention, participants will complete the Avoidance and Fusion Questionnaire for Youth, the Psychological Well-Being Scale, the Depression Anxiety Stress Scale, the Difficulties in Emotion Regulation Scale, and the Emotional Eating subscale of the Dutch Eating Behavior Questionnaire to assess psychological well-being as the primary outcome and experiential avoidance, psychological distress, emotional dysregulation, and emotional eating as secondary outcomes. Repeated-measures ANOVAs (2 × 2) will be conducted. The study will assess the effectiveness of a brief ACT-based intervention for adolescents with obesity in improving their psychological conditions by targeting specific core processes of the ACT framework (openness, awareness, and engagement). Future directions of the study will assess whether these psychological processes will contribute to addressing long-term weight loss.
这项随机对照试验（RCT）旨在评估基于简短接受与承诺疗法（ACT）的干预措施与常规治疗（TAU）相结合，与仅接受 TAU 相比，在改善肥胖青少年（身体质量指数，BMI>年龄和性别的第 97 百分位）的心理状况方面的有效性，其纳入的对象为更广泛的减肥多学科康复计划背景下的患者。将在肥胖康复临床中心住院的 50 名连续肥胖青少年（12-17 岁）招募为连续患者，并随机分配到两个实验组：ACT+TAU 组与 TAU 组。两组均将参加为期 3 周的住院减肥多学科康复计划。ACT+TAU 组包括基于 ACT 的心理干预，以及标准的心理评估和对住院的支持。TAU 组仅包括标准的心理评估和对住院的支持。在心理干预前后，参与者将完成青少年回避融合问卷、心理幸福感量表、抑郁焦虑压力量表、情绪调节困难量表和荷兰饮食行为问卷的情绪性进食分量表，以评估心理幸福感作为主要结果，回避和融合、心理困扰、情绪失调和情绪性进食作为次要结果。将进行重复测量方差分析（2×2）。该研究将评估针对 ACT 框架的特定核心过程（开放性、意识和参与）的简短基于 ACT 的干预措施对改善肥胖青少年心理状况的有效性。该研究的未来方向将评估这些心理过程是否有助于解决长期的体重减轻问题。
