Painhunting Therapy Versus Cognitive Behavioural Therapy for Event-Related Depression (PH-CBT)

2026년 7월 28일 업데이트: Uzakova Sanemkhan, Painhunting LLP

Painhunting Therapy Versus Cognitive Behavioural Therapy for Event-Related Depression: Active-Comparator Randomized Pilot Trial With Adaptive Sample-Size Re-Estimation

This randomized, active-comparator pilot trial will compare Painhunting Therapy with manualized Cognitive Behavioural Therapy (CBT) in adults with event-related depressive symptoms. Participants will be randomly assigned in a 1:1 ratio to receive either Painhunting Therapy or CBT. The primary outcome is depressive symptom severity measured by the Patient Health Questionnaire-9 (PHQ-9) at six weeks after randomization. Secondary outcomes include anxiety symptoms, event-related distress, functional impairment, treatment response and remission, treatment retention, and durability of outcomes at 10 to 12 weeks. The study will also assess treatment fidelity, therapeutic alliance, and selected potential moderators of treatment response. The trial uses a randomized, rater-blinded, parallel-group design with an adaptive sample-size approach.

상세 설명

The purpose of this study is to compare the effectiveness of Painhunting Therapy with manualized Cognitive Behavioural Therapy (CBT), an established psychological treatment for depression, in adults experiencing depressive symptoms associated with adverse life events.

Eligible participants will be randomly assigned in a 1:1 ratio to one of two treatment groups. 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.

The 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.

Outcome 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.

The trial will initially enroll 30 participants, with 15 participants per treatment arm. An interim analysis and prespecified adaptive sample-size procedure will determine continuation toward a planned final analyzed sample of 60 participants, with 30 participants per arm, unless a prespecified stopping criterion is met.

측정값 설명
기간
Depressive symptom severity measured by the Patient Health Questionnaire-9 (PHQ-9)
기간: 6 weeks post-randomization
Depressive symptom severity will be assessed using the Patient Health Questionnaire-9 (PHQ-9). The PHQ-9 consists of 9 items, each scored from 0 to 3, yielding a total score ranging from 0 to 27. Higher scores indicate greater severity of depressive symptoms. The primary comparison between treatment groups will evaluate PHQ-9 scores at six weeks post-randomization, adjusting for baseline PHQ-9.

Painhunting mechanism recognition across treatment sessions
기간: Across Painhunting treatment sessions, approximately 2 to 4 weeks
Prespecified Painhunting treatment mechanisms will be assessed across sessions in participants assigned to the Painhunting arm using the Painhunting mechanism recognition checklist. A stratified sample of 20% of Painhunting session recordings will be independently rated to triangulate self-report against rater-coded mechanism content.
