Police officers are frequently exposed to traumatic events and therefore are at elevated risk of developing post-traumatic stress disorder (PTSD) and other mental health conditions. While evidence-based treatments for PTSD such as prolonged exposure therapy demonstrate effectiveness, residual symptoms and relapse remain problematic outcomes. Improvements in outcomes may be enhanced by modifying psychotherapy processes based upon recent neuroscientific findings. The present study explored incorporating memory reconsolidation principles into evidence-based exposure therapy for PTSD to create memory reconsolidation therapy (MRT). MRT incorporates memory recall followed by a wait period to make memories liable for modification. Using a case series design, three police officers diagnosed with PTSD participated in a maximum of twelve 90-min sessions of MRT and recorded weekly self-report measures of trauma symptoms and psychological distress. Results indicated participants experienced significantly reduced psychological distress with gains maintained over a 3-month follow-up. A significant reliable reduction in trauma symptoms by post-therapy was identified in two of the three cases with the third narrowly missing the clinically significant cut-off. These significant changes were maintained over the 3-month follow-up in one participant, while the maintenance of these improvements in trauma symptoms approached significance in the other two participants. These findings provide preliminary evidence to justify larger future studies to test the efficacy of MRT with police officers experiencing PTSD.

警察经常遭受创伤事件，因此罹患创伤后应激障碍（PTSD）和其他心理健康状况的风险较高。尽管针对PTSD的循证治疗（例如延长暴露治疗）显示出有效性，但残留症状和复发仍然是有问题的结果。通过基于最近的神经科学发现修改心理治疗过程，可以提高预后的改善。本研究探索将记忆再巩固原则纳入针对PTSD的循证暴露治疗中，以创造记忆再巩固治疗（MRT）。MRT结合了内存调用和等待时间，以使内存易于修改。使用案例系列设计，三名被诊断为创伤后应激障碍的警官最多参加了十二次90分钟的捷运，并记录了每周关于创伤症状和心理困扰的自我报告。结果表明，参与者经历了3个月的随访，其心理困扰明显减轻，并且获得了收益。在三例中的两例中，通过治疗后创伤症状得到了显着可靠的降低，第三例几乎没有临床意义上的临界值。在一名参与者的三个月随访中，这些显着变化得以维持，而在其他两名参与者中，创伤症状的这些改善的维持达到了显着水平。这些发现提供了初步的证据，以证明将来有更大的研究可以证明在经历PTSD的警察中测试MRT的有效性。
