Background: Depression is a significant global public health challenge, and mindfulness-based cognitive therapy (MBCT) is an evidence-based secular intervention for depression; however, it incorporates partially Buddhist mindfulness practices. The Satipaṭṭhāna-based thought purification therapy (SB-TPT) is a structured, seven-week intervention that integrates systematic contemplation of the body, feelings, mind, and mental phenomena based on Theravāda Buddhist meditation teachings. This trial aims to assess the comparative effectiveness of SB-TPT, MBCT, and treatment-as-usual (TAU) in adults diagnosed with depressive disorders.
Methods: This study is a parallel-group, three-arm superiority randomized controlled trial. 92 adults aged 18-45 years, who have been diagnosed with depressive disorders (HAM-D-17 >8 and ≤24) according to ICD-10 and DSM-5-TR, will be recruited from a tertiary-care academic psychiatry centre in Varanasi, India. Participants will be randomized (1:1:1) to: SB-TPT plus TAU; MBCT plus TAU; and TAU alone. The primary outcome is change in clinician-rated depressive symptom severity measured by the HAM-D-17. Secondary outcomes include depressive symptoms (BDI-II), mindfulness (FFMQ-H), quality of life (WHOQOL-BREF), and rumination (RRQ). Assessments will be conducted at baseline, post-intervention, and at the 3-month follow-up. Data will be analyzed using repeated-measures analysis of variance and intention-to-treat principles.
Conclusions: This trial will provide the first randomized evaluation of a structured Satipaṭṭhāna-based intervention compared with MBCT and treatment as usual for depressive disorders. Findings may contribute to understanding the clinical effectiveness of traditionally grounded contemplative approaches within contemporary mental health settings.
