Interpersonal therapy for depression in Breast Cancer

描述（由申请人提供）：抑郁障碍和症状在乳腺癌患者中普遍存在，在癌症治疗过程中恶化，在癌症治疗后持续存在，显著损害生活质量，并降低对癌症治疗的依从性和生存率。然而，对于乳腺癌患者的抑郁症还没有确定的治疗方法。随着癌症幸存者越来越普遍，迫切需要建立一个经验基础，为这一人群提供有效的循证治疗。我们提出了一项随机临床试验，以比较人际心理治疗（IPT），解决问题的治疗（PST），和短期支持性心理治疗（BSP）在减轻抑郁症状和改善生活质量的乳腺癌患者与DSM-IV重性抑郁症（MDD）的疗效。IPT是一种手动的、有时间限制的治疗方法，在治疗MDD方面显示出重复的疗效，并且在不同年龄范围、文化、形式和递送方式上具有显著的灵活性和疗效。PST是一种简短的，手动形式的认知行为疗法（CBT），已被用于治疗癌症患者的抑郁症，并显示出非常有希望的结果。BSP是临床实践中常用的一种相对非结构化的心理治疗，专注于患者的情感。它通过仔细倾听和同情病人，验证和鼓励容忍病人的情绪，建立了一个强大的治疗联盟。它在患有癌症和其他医学疾病的抑郁症患者中显示出有希望的结果。除了抑郁症状的改善，社会人口学特征，临床因素，抑郁症治疗依从性和结果护理之间的关系将被检查。每种疾病的患者将在16周内接受12次治疗，并将再随访4个月以检查反应的稳定性。我们的模型是基于现有的文献，我们在乳腺癌患者的生存护理的长期经验，提出的治疗的理论吸引力和有前途的数据，以及广泛的初步数据。此外，拟议的研究将通过检查治疗结果的中介者和调节者来深入了解影响关键结果的因素。通过研究一个富有成效的研究团队提供的有希望的试点数据的理论为基础的治疗模型，我们相信我们可以帮助产生迫切需要的经验基础，为抑郁的乳腺癌患者提供有效的治疗。公共卫生相关性：尽管DSM-IV重度抑郁症（MDD）在乳腺癌患者中的患病率和不良后果，但还没有确定的治疗方法。我们提出了一项随机临床试验，以比较人际心理治疗（IPT），解决问题的治疗（PST）和短期支持治疗（BSP）在改善抑郁症乳腺癌患者的抑郁症状和生活质量的疗效。我们希望这项研究的结果将有助于建立迫切需要的经验基础，为这一人群提供有效的循证治疗。

DESCRIPTION (provided by applicant): Depressive disorders and symptoms are prevalent in patients with breast cancer, worsen over the course of cancer treatment, persist after cancer therapy, significantly impair quality of life, and decrease adherence to cancer therapy and survival. Yet, there are no established treatments for depression in breast cancer patients. As surviving cancer becomes increasingly common, there is an urgent need to develop an empirical basis to provide effective, evidence-based treatments to this population. We propose a randomized clinical trial to compare the efficacy of Interpersonal Psychotherapy (IPT), Problem-Solving Therapy (PST), and Brief Supportive Psychotherapy (BSP) in alleviating depressive symptoms and improving quality of life for breast cancer patients with DSM-IV major depressive disorder (MDD). IPT, a manualized, time-limited therapy, has shown repeated efficacy in treating MDD, and remarkable flexibility and efficacy across age ranges, cultures, formats, and modes of delivery. PST is a brief, manualized form of cognitive-behavioral therapy (CBT) that has been adapted to treat depression in cancer patients and shown highly promising results. BSP is a relatively unstructured psychotherapy commonly used in clinical practice that focuses on the patient's affect. It builds a strong therapeutic alliance through listening carefully and empathically to the patient, validating and encouraging toleration of the patient's emotions. It has shown promising results in depressed individuals with cancer and other medical illnesses. In addition to improvement in depressive symptoms, relationships between sociodemographic characteristics, clinical factors, depression treatment adherence, and outcomes care will be examined. Patients in each condition will receive 12 therapy sessions within a 16-week period, and will be followed for another 4 months to examine the stability of response. Our model is based on the existing literature, our long-standing experience in survivorship care of breast cancer patients, the theoretical appeal and promising data of the proposed treatments, and a broad range of preliminary data. In addition, the proposed study will yield insight into factors that influence key outcomes by examining mediators and moderators of treatment outcome. By investigating a theoretically-based treatment model with promising pilot data from a productive research team, we believe we can help generate the urgently needed empirical foundations for the provision of effective treatment to depressed breast cancer patients. PUBLIC HEALTH RELEVANCE: Despite the prevalence and adverse consequences of DSM-IV major depressive disorder (MDD) for breast cancer patients, no established treatments exist. We propose a randomized clinical trial to compare the efficacy of Interpersonal Psychotherapy (IPT), Problem-Solving Therapy (PST) and Brief Supportive Therapy (BSP) in improving depressive symptoms and quality of life among breast cancer patients with MDD. We hope that the results of this study will help to build the urgently needed empirical basis for effective, evidence-based treatments for this population.
