Posttraumatic stress disorder (PTSD) is the most highly prevalent mental health disorder among U.S. military Veterans. PTSD is a chronic disorder that is associated with significant morbidity, mortality, disability, and costly health care expenditures. The clinical impairment associated with PTSD among Veterans is severe and associated with comorbid depression, suicidality, substance abuse, physical health problems, interpersonal violence, and neuropsychiatric impairment. Despite these pervasive health consequences, the current treatment services offered to Veterans do not adequately address PTSD. Several promising psychosocial interventions, including Prolonged Exposure (PE) therapy, have been developed for the treatment of PTSD. Although PE is one of the most widely used evidence-based treatments for PTSD, there is substantial room for improvement in outcomes and retention rates. For example, approximately one-third of patients dropout of PE treatment prematurely, and the highest dropout rates occur among Veterans. Consistent with the VA Office of Research and Development initiative to develop effective treatments for PTSD, identifying pharmacotherapies to enhance PTSD treatment retention and outcomes is critical. Accumulating data from our group and others suggests that oxytocin is a promising candidate to achieve this goal. Oxytocin is known to promote prosocial behaviors associated with successful psychosocial treatment outcomes (e.g., trust, safety, social cognition) and has demonstrated positive effects on extinction learning in animal and human stress models. Furthermore, recent neuroimaging studies show that oxytocin has the ability to ameliorate dysregulation of the corticolimbic brain circuitry, which is a central component of the pathophysiology and maintenance of PTSD. In the only study to date examining the feasibility, acceptability, and preliminary efficacy of augmenting PE with oxytocin, our group found that participants randomized to the oxytocin condition demonstrated lower PTSD and depression symptoms during PE, and had higher working alliance scores compared to participants randomized to the placebo condition. Therefore, the primary objective of the proposed two-site Phase II study is to examine the ability of oxytocin (vs. placebo) combined with PE therapy to (1) reduce PTSD symptom severity, (2) improve rate of PTSD symptom improvement, and (3) improve PE adherence and retention rates. To accomplish these objectives, we will employ a randomized, double-blind, placebo-controlled trial and use standardized, repeated dependent measures of change at five time points (baseline, mid-treatment, end of treatment, and 3 and 6 month follow-up). The proposed study directly addresses the mission of the Veterans Health Administration Blueprint for Excellence in that it seeks to advance personalized and proactive mental health care opportunities for Veterans. Findings from this study will provide critical new information regarding the efficacy of oxytocin to augment psychosocial treatment for PTSD, as well as information regarding the neurobiological mechanisms underlying PTSD and positive treatment response.

创伤后应激障碍（PTSD）是美国最常见的心理健康障碍。 退伍军人。创伤后应激障碍是一种慢性疾病，与显着的发病率、死亡率， 残疾和昂贵的医疗保健支出。退伍军人创伤后应激障碍的临床损害 严重并伴有抑郁症、自杀倾向、药物滥用、身体健康 问题、人际暴力和神经精神障碍。尽管这些普遍的健康 因此，目前为退伍军人提供的治疗服务并不能充分解决PTSD问题。 一些有希望的心理社会干预措施，包括延长暴露（PE）疗法，已经被 用于治疗创伤后应激障碍虽然PE是最广泛使用的循证医学之一， PTSD的治疗，在结果和保留率方面有很大的改善空间。比如说， 大约三分之一的患者过早退出PE治疗， 在退伍军人中。与VA研究和开发办公室的倡议一致， 治疗PTSD，确定药物疗法，以提高PTSD治疗的保留和结果是 很危险从我们小组和其他人积累的数据表明，催产素是一个有希望的候选人， 实现这一目标。众所周知，催产素可以促进与成功相关的亲社会行为。 心理社会治疗结果（例如，信任，安全，社会认知），并已显示出积极的影响 在动物和人类压力模型中的灭绝学习。此外，最近的神经成像研究表明， 催产素有能力改善皮质边缘脑回路的失调，皮质边缘脑回路是中枢神经系统， PTSD的病理生理学和维持的组成部分。在迄今为止唯一一项研究中， 可行性、可接受性和用催产素增强PE的初步疗效，我们的研究小组发现， 随机分配到催产素组的参与者表现出较低的PTSD和抑郁症状 在PE期间，与随机分配到安慰剂组的参与者相比， 条件因此，拟议的两个中心II期研究的主要目的是检查 催产素（与安慰剂相比）联合PE治疗（1）减轻PTSD症状严重程度，（2）改善 PTSD症状改善率;（3）提高PE依从性和保留率。到 为了实现这些目标，我们将采用随机、双盲、安慰剂对照试验， 在5个时间点（基线、治疗中期、治疗结束）标准化、重复依赖性变化测量 治疗，3个月和6个月随访）。拟议的研究直接涉及退伍军人的使命 健康管理卓越蓝图，因为它寻求推进个性化和积极主动的心理 为退伍军人提供医疗保健机会。这项研究的结果将提供关键的新信息， 催产素加强创伤后应激障碍心理社会治疗的功效，以及有关 创伤后应激障碍的神经生物学机制和积极的治疗反应。
