Current research on treatment predictors and long-term effects of trauma-focused interventions for (unaccompanied) refugee minors is limited. This secondary analysis of a recent randomised controlled trial (RCT), evaluating the trauma-focused group intervention “Mein Weg” (English “My Way”) compared to usual care, investigated several refugee-specific factors such as treatment predictors and sustainability of treatment gains. In total N = 50 participants (Mage = 17.00, 94% male) were included in this analysis. Evaluation of 3-month follow-up data included: posttraumatic stress symptoms [(PTSS) CATS-Self, CATS-Care], depression (PHQ-8), and dysfunctional posttraumatic cognitions (CPTCI-S). Baseline symptom severity of the above-mentioned measures, trauma load and socio-demographic factors were investigated as the treatment predictors. Intention-to-treat-analyses (ITT) revealed the sustainability of treatment effects in self-reported PTSS (pre to post change: 6.48 ± 1.60, d = 0.62, p < 0.001; post to 3-month follow-up change: 1.41 ± 1.96, d = 0.11, p = 0.47) and depression (pre to post change: 7.82 ± 2.09, d = 0.64, p < 0.001; post to 3-month follow-up change: 1.35 ± 2.17, d = 0.05, p = 0.54). Country of origin alone was a significant predictor of the change in PTSS (b = − 8.22 ± 3.53, t(30) = − 2.33, p = 0.027), and baseline levels of depression were a significant predictor of the change in depression (b = 0.83 ± 0.19, t(33) = 4.46, p < 0.001). This group intervention can serve as a valuable component in a stepped care approach with promising long-term effects for young refugees. Trial registration DRKS, #DRKS00010915.

针对无人陪伴的年轻难民的以创伤为重点的团体干预：“Mein Weg”——治疗结果的预测因素和治疗效果的可持续性

目前对（无人陪伴的）难民未成年人的治疗预测因素和以创伤为重点的干预措施的长期影响的研究是有限的。这项对最近一项随机对照试验 (RCT) 的二次分析，评估了以创伤为重点的小组干预“Mein Weg”（英语“My Way”）与常规护理相比，调查了几个难民特定因素，如治疗预测因素和治疗的可持续性收益。总共有 N = 50 名参与者（Mage = 17.00，94% 男性）被纳入该分析。对 3 个月随访数据的评估包括：创伤后应激症状 [(PTSS) CATS-Self, CATS-Care]、抑郁症 (PHQ-8) 和功能失调的创伤后认知 (CPTCI-S)。调查上述措施的基线症状严重程度、创伤负荷和社会人口因素作为治疗预测因素。意向治疗分析 (ITT) 揭示了自我报告的 PTSS 治疗效果的可持续性（变化前后：6.48 ± 1.60，d = 0.62，p < 0.001；3 个月随访变化后：1.41 ± 1.96，d = 0.11，p = 0.47）和抑郁症（变化前后：7.82 ± 2.09，d = 0.64，p < 0.001；3 个月随访变化后：1.35 ± 2.17，d = 0.05，p = 0.54)。仅原籍国是 PTSS 变化的重要预测因子（b = − 8.22 ± 3.53，t(30) = − 2.33，p = 0.027），抑郁症的基线水平是抑郁症变化的重要预测因子（b = 0.83 ± 0.19，t(33) = 4.46，p < 0.001)。这种集体干预可以作为阶梯式护理方法的重要组成部分，对年轻难民有希望的长期影响。试用注册 DRKS，#DRKS00010915。2016 年 9 月 15 日注册，https://www.drks。
