The aim of this paper is to analyse the factors associated with the dropout from brief psychotherapy for adults with major depressive disorder (MDD) treated at a mental health outpatient clinic. This is a randomized clinical trial with two models of psychotherapy: cognitive behavioural therapy (CBT) and supportive expressive dynamic psychotherapy (SEDP). MDD and anxiety disorders were evaluated through the Mini International Neuropsychiatric Interview-Plus. The personality disorders were evaluated by the Millon Clinical Multiaxial Inventory-III. The severity of depressive symptoms was measured using the Beck Depression Inventory-II and resilience through Resilience Scale. Of the 215 participants, 41.9% abandoned psychotherapy (n = 90), and, of these, 54.4% (n = 49) abandoned after the fourth session. The proportion of psychotherapy dropout was higher among those with nonwhite skin colour, belonging to economic classes C and D, who had children and whose depressive symptoms were moderate. Presence of obsessive–compulsive personality trait was protective against dropout. The damage caused by this abrupt interruption is evident for all those involved in the psychotherapeutic process, so the clinician should pay attention to the predictors found in this study in order to develop strategies that promote therapeutic adherence.

重度抑郁症短暂心理治疗中的辍学：随机临床试验

本文的目的是分析与在心理健康门诊接受治疗的重度抑郁症 (MDD) 成人的简短心理治疗退出相关的因素。这是一项随机临床试验，采用两种心理治疗模型：认知行为疗法 (CBT) 和支持性表达性动态心理疗法 (SEDP)。通过 Mini International Neuropsychiatric Interview-Plus 评估 MDD 和焦虑症。人格障碍通过 Millon Clinical Multiaxis Inventory-III 进行评估。抑郁症状的严重程度使用贝克抑郁量表-II 和复原力量表测量。在 215 名参与者中，41.9% 放弃了心理治疗（n  = 90），其中 54.4%（n = 49) 第四次会议后放弃。非白人肤色、经济阶层C和D、有孩子且抑郁症状中度的人群中，心理治疗退出的比例较高。强迫性人格特质的存在可以防止辍学。这种突然中断造成的损害对所有参与心理治疗过程的人来说都是显而易见的，因此临床医生应注意本研究中发现的预测因素，以制定促进治疗依从性的策略。
