DESCRIPTION (provided by applicant): It has been estimated that each new episode of depression increases a patient's cumulative risk for relapse by 16% and those patients who have experienced three or more past depressions are at an elevated risk of staying chronically depressed (Solomon 2000). Patients with recurrent depression are, therefore, a logical group for targeted prevention efforts. To date, the best validated and most widely used approach for preventing relapse in recurrent depression is maintenance medication. However, the protection afforded lasts only as long as patients continue to take their medication. In light of this concern, there has been a growing interest in the use of treatments that combine recovery through medication with psychological prevention of relapse/recurrence (Fava et al., 1998). One such treatment is Mindfulness-Based Cognitive Therapy (MBCT), a group intervention designed to train recovered depressed patients to disengage from mood-linked depressive thinking styles that may trigger relapse/recurrence. While there are preliminary data on MBCT's preventative effects, we do not know how well this treatment fares in comparison with the most pervasive preventive intervention for depression, namely maintenance medication. We plan to identify a sample of 272 recurrently depressed outpatients and, during the acute treatment phase of this study, provide antidepressant medication. Remitted patients will then be randomly assigned to receive either maintenance medication, be withdrawn from medication and receive MBCT or be withdrawn and receive placebo and clinical management. All patients will then be followed for the next eighteen months. Our main hypotheses are that MBCT and maintenance medication will not differ in their efficacy, and that both will outperform placebo and clinical management. We will also perform analyses to examine a possible cognitive mechanism underlying MBCT's effectiveness as well as estimate the relative costs of MBCT compared to maintenance medication for prevention of relapse. Findings from this study would have clear public health significance because MBCT could prove to be an additional effective treatment for recurrently depressed patients who require maintenance courses of treatment to prevent relapse/recurrence.

描述(由申请人提供)：据估计，每出现一次新的抑郁症发作，患者的累积复发风险增加16%，那些过去经历过三次或更多抑郁症的患者保持慢性抑郁症的风险增加(所罗门2000)。因此，复发性抑郁症患者是有针对性的预防措施的合乎逻辑的群体。到目前为止，预防复发性抑郁症复发的最有效和最广泛使用的方法是维持药物。然而，这种保护只有在患者继续服药的情况下才能持续。鉴于这一关切，人们对使用将药物康复与心理预防复发/复发相结合的治疗方法越来越感兴趣(Fava等人，1998年)。其中一种治疗方法是基于正念的认知疗法(MBCT)，这是一种旨在训练康复的抑郁症患者摆脱可能引发复发/复发的与情绪相关的抑郁思维方式的小组干预。虽然有关于MBCT预防效果的初步数据，但我们不知道这种治疗与最普遍的抑郁症预防干预措施，即维持药物相比，效果如何。我们计划确定272名反复抑郁的门诊患者的样本，并在本研究的急性治疗阶段提供抗抑郁药物。然后，缓解的患者将被随机分配到接受维持药物治疗、停药并接受MBCT或停药并接受安慰剂和临床治疗。所有患者将在接下来的18个月内接受随访。我们的主要假设是，MBCT和维持性药物的疗效不会有什么不同，而且两者的表现都将优于安慰剂和临床治疗。我们还将进行分析，以检查MBCT有效性的可能认知机制，并估计MBCT与用于预防复发的维持药物相比的相对成本。这项研究的结果将具有明显的公共卫生意义，因为MBCT可能被证明是一种额外的有效治疗方法，用于需要维持疗程以防止复发/复发的复发性抑郁症患者。
