Anger dysregulation is part of a broad range of clinical disorders, and as a dynamic risk factor for aggression anger is highly relevant in clinical populations. Problems of anger and reactive aggression are trans-diagnostic and treatments should target the mechanisms involved in problematic anger across disorders. There is empirical evidence that anger rumination is associated with anger as well as aggression. Because rumination-focused CBT (RfCBT) has shown that reduction in rumination seems to be associated with transdiagnostic reductions in symptoms, the present study aimed at extending the applicability of the RfCBT model to target problematic anger in a case of schizotypal personality disorder (SPD). The current study was a clinical case study with a patient suffering from problematic anger and anger rumination, and diagnosed with schizotypal personality disorder (SPD) receiving 25 sessions of rumination-focused CBT (RfCBT) for problematic anger. The primary focus was on anger and anger rumination, which was reduced during therapy, and maintained in the 3 months follow up. Results on the measures of repetitive negative thinking also showed a decrease, however symptoms of depression and anxiety had increased from pre- to post treatment. RfCBT can be applied to a case of SPD with problematic anger, thereby showing proof of concept for a transdiagnostic use of RfCBT and opening up for future research in this area. The applicability of RfCBT to anger problems among patients diagnosed with SPD needs to be replicated in a larger sample of patients diagnosed with SPD/problematic anger and anger rumination.

愤怒失调是许多临床疾病的一部分，并且作为侵略性愤怒的动态危险因素与临床人群高度相关。愤怒和反应性攻击的问题是诊断性疾病，治疗应针对各种疾病中引起问题的愤怒的机制。有经验证据表明，愤怒的反省与愤怒和侵略有关。因为以反刍为中心的CBT（RfCBT）已显示，反刍的减少似乎与症状的转诊减少有关，所以本研究旨在扩展RfCBT模型的适用性，以针对精神分裂型人格障碍（SPD）的有问题的愤怒。当前的研究是一项临床案例研究，患者患有愤怒的愤怒和愤怒反刍，并被诊断患有精神分裂型人格障碍（SPD），接受了25场针对反刍的CBT（RfCBT），以解决愤怒的问题。主要重点是愤怒和愤怒反刍，在治疗过程中减少了愤怒，并在3个月的随访中得以维持。重复否定性思维测验的结果也有所减少，但是从治疗前到治疗后，抑郁和焦虑的症状有所增加。RfCBT可以应用于愤怒有问题的SPD病例，从而显示出对RfCBT进行转诊使用的概念证明，并为该领域的未来研究开辟了道路。RfCBT在诊断为SPD的患者中愤怒问题的适用性需要在被诊断为SPD /有问题的愤怒和愤怒反刍的更大样本患者中重复。
