传统上，抑郁症的治疗主要集中在减少患者的症状或缺陷，而较少关注建立积极的资源。本研究旨在比较经验性积极心理学干预(PPI)和认知-行为疗法(CBT)方案的有效性。这项对照临床试验包括96名患有DSM-IV诊断为严重抑郁症或心境恶劣的成年女性。参与者被盲目分配到10个疗程的PPI(n=47)或CBT(n=49)小组治疗条件下。意向处理分析显示，两种干预措施均能有效缓解临床症状，提高幸福感。两组在主要结果(即抑郁症状的严重程度和临床诊断)或次要结果(例如积极和消极的情绪，以及对生活的满意度)方面都没有显著差异。即使在最严重抑郁的参与者中，PPI和CBT之间也没有出现差异。如果进一步的临床研究证实了这些结果，这将扩大患者和专业人员的治疗选择。
Traditionally, treatments for depression have been primarily focused on reducing patients' symptoms or deficits and less concerned with building positive resources. This study aims to compare the efficacy of a manualized protocol of empirically-validated positive psychology interventions (PPI) with a cognitive-behavioral therapy (CBT) protocol. This controlled clinical trial included 96 adult women with a DSM-IV diagnosis of major depression or dysthymia. Participants were blindly allocated to a 10-session PPI (n = 47) or CBT (n = 49) group therapy condition. Intention to treat analysis showed that both interventions were effective in reducing clinical symptoms and increasing well-being. There were no significant differences between groups in either main outcomes (i.e., severity of depressive symptoms and clinical diagnosis) or secondary outcomes (e.g., positive and negative affect, and satisfaction with life). Even within the most severely depressed participants, no differences between PPI and CBT emerged. If further clinical studies confirm these results, this would widen treatment choice for both patients and professionals.
