- Abstract
- Objectives: Broadly considered as a transdiagnostic feature of anxiety, mood, and stress-related disorders, rumination is associated with slower treatment response, lower rates of recovery, and higher rates of relapse. Accordingly, research has focused on the development of rumination-focused treatment. Recently, transcranial Direct Current Stimulation (tDCS), mostly applied over the frontal brain areas (as a proxy of attention control), has emerged as a potential new tool for targeting rumination. Yet, study-to-study variations in stimulation, targeted brain regions, and research protocols preclude a comprehensive understanding of the impact of tDCS on rumination. Methods: To tackle this issue, we conducted a preregistered systematic review of the published studies aiming at modifying rumination via tDCS. Only sham-controlled studies reporting the effects of tDCS on at least one measure of rumination among healthy participants or patients with psychiatric disorders were included. Moreover, we also assessed risk of methodological bias in this field. Results: Heterogeneity in results, stimulation parameters, and study designs was high. Several methodological limitations were also identified. Conclusion: Implications for both basic and clinical research in the field of rumination will be discussed. Methodological recommendations for future studies will be also be discussed.
