Non-randomized trial evaluated mindfulness and psychoeducation impacts on rumination and cognitive bias in psychiatric clients, suggesting engagement may improve.
Purpose: Mindfulness-based interventions may reduce depression and rumination; however, rumination can hinder engagement and increase dropout. The current study evaluated the preliminary efficacy of a nurse-led, mindfulness-based program incorporating psychoeducation on rumination, compared to usual psychiatric daycare alone. Method: A prospective, multicenter, non-randomized controlled trial was conducted with adults presenting depressive symptoms in daycare settings (intervention: n = 20; control: n = 17). Primary outcomes were rumination and dropout rates. Results: No significant between-group difference was found in rumination, although small but meaningful pre-post effect sizes were observed only within the intervention group. Dropout rates were 5% (intervention) and 11.8% (control). A significant between-group difference was observed in the “fortune-teller error” subscale of cognitive bias (secondary outcome), with medium pre-post effect sizes in the intervention group. Conclusion: The program may help reduce cognitive biases and improve engagement, even among individuals with depressive symptoms.
