The Painhunting Therapy arm will receive a brief structured course of therapy, with a minimum planned dose of three sessions except for participants meeting prespecified early-remission criteria, and additional sessions permitted when clinically indicated. The CBT arm will receive manualized CBT for depression delivered over approximately six to eight sessions. The intended primary treatment comparison is approximately three Painhunting sessions versus six CBT sessions, reflecting the typical delivery format of each intervention rather than a matched-dose comparison.\n\nThe primary endpoint is PHQ-9 score at six weeks after randomization. Additional assessments will examine depressive symptoms at earlier and later time points, anxiety symptoms, event-related distress, functional impairment, treatment response and remission, treatment retention, and maintenance of outcomes at 10 to 12 weeks.\n\nOutcome assessments at key follow-up time points will be conducted by assessors blinded to treatment allocation. Treatment adherence and fidelity will be independently assessed in both treatment arms using prespecified treatment-specific rating instruments.\n\nThe trial will initially enroll 30 participants, with 15 participants per treatment arm.
