对消极情绪和焦虑的沉思反应的倾向增加是抑郁症复发的重要脆弱性因素。在这项研究中，我们调查了反刍和焦虑担忧的变化轨迹，在一个为期八周的正念认知疗法（MBCT）的过程中，复发性抑郁症患者的复发预防。来自随机对照试验MBCT组的104名参与者提供了每周评级。混合线性模型表明，在反刍和担心的过程中的程序遵循一般的线性趋势的变化，与此趋势周围的显着变化所示的模型拟合随机斜率后显着增加。对个别轨迹的探索表明，尽管波动很大，但几乎没有证据表明突然增加是经常发生的。研究结果符合一般的概念，即在正念认知疗法中，脆弱性的降低主要是通过定期和一致的实践来驱动的，而突然的认知洞察力本身不太可能导致持久的影响。
Increased tendencies towards ruminative responses to negative mood and anxious worry are important vulnerability factors for relapse to depression. In this study, we investigated the trajectories of change in rumination and anxious worry over the course of an eight-week programme of mindfulness-based cognitive therapy (MBCT) for relapse prevention in patients with a history of recurrent depression. One hundred and four participants from the MBCT-arm of a randomized-controlled trial provided weekly ratings. Mixed linear models indicated that changes in rumination and worry over the course of the programme followed a general linear trend, with considerable variation around this trend as indicated by significant increases in model fit following inclusion of random slopes. Exploration of individual trajectories showed that, despite considerable fluctuation, there is little evidence to suggest that sudden gains are a common occurrence. The findings are in line with the general notion that, in MBCT, reductions in vulnerability are driven mainly through regular and consistent practice, and that sudden cognitive insights alone are unlikely to lead into lasting effects.
