OBJECTIVE The study explored the presence of different patterns of change in a sample of patients who received cognitive therapy for depression sequentially in two different formats: group and individual. Our hypothesis was that patients' baseline characteristics (e.g., symptom severity, self-esteem) would discriminate patterns of response to group and individual therapy. METHOD 108 adults who met criteria for depression and completed the treatments included in a randomized controlled trial (RCT) were assessed with the Beck Depression Inventory-II (BDI-II), the Clinical Outcome in Routine Evaluation-Short Form B (CORE-SFB), the Global Assessment of Functioning (GAF), and the repertory grid technique. Growth mixture modeling was carried out to identify the patterns of change. Mixed linear models and repeated measures analysis of variance were performed to compare patients' characteristics in each pattern. Multinomial logistic regression was used to compute predictive models for the patterns from patients' characteristics. Finally, hierarchical linear regression was used to establish the power of each pattern to predict treatment outcome. RESULTS A 3-class solution was obtained: group therapy improvers, individual therapy improvers, and nonimprovers. Group therapy improvers started therapy with less severe levels of depression and psychological distress, higher functioning and self-esteem, lower perceived social isolation, and lower dilemmatic construction of the self than the other groups. Individual therapy improvers and nonimprovers presented similar characteristics at baseline. However, a significant proportion of nonimprovers presented a concurrent diagnosis of fibromyalgia. CONCLUSION The greater the impairment that patients present at baseline, the more likely they are to benefit from individual therapy after group therapy. A diagnosis of fibromyalgia can be considered a risk factor for therapy failure in the treatment of depression. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

小组和个人抑郁症心理治疗的变化模式及其与结果和随访的关系。

目的这项研究探索了依次接受两种不同形式的抑郁症认知疗法的患者样本中不同变化模式的存在：群体和个体。我们的假设是，患者的基线特征（例如症状严重程度，自尊心）将区分对集体和个体疗法的反应方式。方法对108名符合抑郁标准并完成了随机对照试验（RCT）治疗的成年人进行了贝克抑郁量表II（BDI-II），常规评估-简短表格B的临床结果（CORE-SFB）的评估），全局功能评估（GAF）和库格式技术。进行生长混合物建模以识别变化模式。进行了混合线性模型和方差的重复测量分析，以比较每种模式下患者的特征。多项逻辑回归用于根据患者特征计算模式的预测模型。最后，使用分层线性回归来建立每种模式的功效以预测治疗结果。结果获得了3类解决方案：小组治疗改进剂，个体治疗改进剂和非改进剂。小组治疗改进者开始治疗时，与其他小组相比，抑郁症的严重程度不那么严重，抑郁和心理困扰程度更高，功能和自尊心更高，感知的社会孤立感更低，自我的困境结构也更低。个体治疗改善者和非改善者在基线时表现出相似的特征。然而，大量非改善者同时诊断为纤维肌痛。结论患者在基线时出现的损害越大，他们在团体治疗后受益于个体治疗的可能性就越大。纤维肌痛的诊断可以认为是抑郁症治疗失败的危险因素。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
