Brief Summary
This study is a longitudinal, multicenter, single-blind, two-arm randomized controlled trial designed to evaluate the effectiveness of Multi-Modal Cognitive Processing Therapy (MMCPT) for individuals with posttraumatic stress disorder (PTSD). Participants will be randomly assigned to either the intervention group receiving MMCPT or a control group receiving treatment-as-usual (TAU). The intervention follows the standard CPT manual developed by Resick and consists of twelve weekly 90-minute individual sessions. The primary outcomes include PTSD symptom severity assessed by the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) and the PTSD Checklist for DSM-5 (PCL-5). Secondary outcomes include sleep quality (actigraphy, PSQI), anxiety (STAI), depression (HDRS-17), remission rate, and posttraumatic growth (PTGI). Assessments will occur at baseline, mid-treatment, post-treatment, and at 3-, 6-, 9-, and 12-month follow-ups.

Study Arms (2)
Cognitive Processing Therapy (CPT)
EXPERIMENTALParticipants in this arm will receive 12 weekly individual sessions of Cognitive Processing Therapy (CPT), based on the Resick protocol. Each session will last 90 minutes and will be delivered by a trained therapist. The therapy integrates cognitive restructuring, trauma-related belief processing, and behavioral assignments.
Treatment as Usual (TAU)
ACTIVE COMPARATORParticipants in this group will receive routine outpatient psychiatric care as determined by their clinician, which may include medication, general supportive therapy, or psychoeducation, but will not include structured CPT sessions.
Interventions
Participants will receive 12 weekly 90-minute individual sessions of Cognitive Processing Therapy (CPT) following the Resick manual. The intervention includes cognitive restructuring, trauma-related belief processing, and structured behavioral assignments. Sessions are delivered by trained therapists.
Participants will receive routine outpatient psychiatric care as determined by clinicians. This may include medication, general supportive therapy, or psychoeducation, but will not include structured CPT sessions.
