Rumination is theorized to be a cognitive avoidance process that is implicated in several manifestations of psychopathology. Few interventions directly target rumination as a core process maintaining emotional disorder symptoms. This pilot study compared the feasibility and preliminary efficacy of self-directed behavioral approaches for reducing rumination. Participants (N = 60) with elevations in rumination were randomized to 3 weeks of self-directed interventions: (a) scheduled rumination time; (b) a strategy combining mindfulness, shaping, and disengagement strategies; or (c) self-monitoring control. Both active treatment conditions outperformed self-monitoring control on post-treatment depression scores. Scheduled rumination time significantly outperformed the other two conditions on measures of rumination and worry. No between-group differences emerged on the secondary outcome (i.e., anxiety symptoms). Brief, self-directed, behavioral interventions targeting rumination are feasible and demonstrate preliminary efficacy. Scheduled rumination time shows moderate to large effects. The use of a small, non-treatment seeking sample was the primary limitation.

反刍被认为是一种认知回避过程，与精神病理学的几种表现有关。很少有干预措施直接将反刍作为维持情绪障碍症状的核心过程。这项试点研究比较了自我指导的行为方法减少反刍的可行性和初步效果。参与者（N = 60) 反刍增加的人被随机分配到 3 周的自主干预：(a) 预定的反刍时间；(b) 结合正念、塑造和脱离接触策略的策略；(c) 自我监测控制。两种积极的治疗条件都优于治疗后抑郁评分的自我监测控制。预定的反刍时间在反刍和忧虑方面明显优于其他两个条件。次要结局（即焦虑症状）没有出现组间差异。针对反刍的简短、自我导向的行为干预是可行的，并显示出初步的疗效。预定的反刍时间显示出中到大的影响。使用小的、非寻求治疗的样本是主要限制。
