An appreciation of cognitive predictors of change in treatment outcome may help to better understand differential treatment outcomes. The aim of this study was to examine how rumination and mindfulness impact on treatment outcome in two group-based interventions for non-melancholic depression: Cognitive Behaviour Therapy (CBT) and Mindfulness-Based Cognitive Therapy (MBCT).
Sixty-nine participants were randomly allocated to either 8-weekly sessions of group CBT or MBCT. Complete data were obtained from 45 participants (CBT = 26, MBCT = 19). Outcome was assessed at completion of group treatments.
Depression scores improved for participants in both group interventions, with no significant differences between the two treatment conditions. There were no significant differences between the interventions at post-treatment on mindfulness or rumination scores. Rumination scores significantly decreased from pre- to post-treatment for both conditions. In the MBCT condition, post-treatment rumination scores were significantly associated with post-treatment mindfulness scores.
Results suggest that decreases in rumination scores may be a common feature following both CBT and MBCT interventions. However, post-treatment rumination scores were associated with post-treatment mindfulness in the MBCT condition, suggesting a unique role for mindfulness in understanding treatment outcome for MBCT.
对治疗结果变化的认知预测因素的理解，可能有助于更好地理解不同的治疗结果。本研究旨在检验在两种基于团体的非忧郁性抑郁症治疗方法（认知行为治疗（CBT）和正念认知疗法（MBCT））中，反刍和正念如何影响治疗结果。
69 名参与者被随机分配到每周 8 次的团体 CBT 或 MBCT 治疗中。从 45 名参与者中获得了完整的数据（CBT=26，MBCT=19）。在团体治疗结束时评估了结果。
两组干预措施的参与者抑郁评分均有所改善，两种治疗条件之间无显著差异。在正念或反刍评分方面，两种干预措施在治疗后没有显著差异。对于两种情况，反刍评分均从治疗前到治疗后显著降低。在 MBCT 条件下，治疗后反刍评分与治疗后正念评分显著相关。
结果表明，CBT 和 MBCT 干预后反刍评分的降低可能是共同特征。然而，在 MBCT 条件下，治疗后反刍评分与治疗后正念评分相关，表明正念在理解 MBCT 治疗结果方面具有独特的作用。
