The objective of this pragmatic trial is to evaluate the beneficial and harmful effects of Patient-centred Modular Cognitive Behavioural Therapy (PACE) compared with the standard post-traumatic stress disorder (PTSD) treatment, Prolonged Exposure (PE), for adults with an ICD-11 diagnosis of Complex post-traumatic stress disorder (CPTSD).
This trial is designed as an investigator-initiated, multi-centre, parallel group, randomised clinical superiority trial of PACE versus standard PTSD treatment, PE, for ICD-11 CPTSD. The total sample size will be 228 participants. The trial will take place at the Danish Veteran Centre and two clinics in the Mental Health Services in Denmark. The participants will be adult military veterans and psychiatric outpatients with ICD-11 CPTSD. After giving their consent, participants will be randomly assigned (1:1) to receive either PACE or PE.
The experimental intervention will be 26 hours PACE (delivered as 26 1-hour sessions of weekly individual psychotherapy). The control intervention will be 25.5 hours PE therapy (17 sessions of weekly individual psychotherapy delivered for 90-minutes).
Outcome assessors, data managers, statisticians, and conclusion drawers will be blinded to group allocation. The primary outcome will be clinician-rated ICD-11 CPTSD symptom severity assessed with the International Trauma Interview (ITI) at 9 months after randomisation. Secondary outcomes include serious adverse events, suicide attempts, symptoms of depression, stress, and anxiety, alcohol use problems, mental well-being, and functional impairment assessed at 9 months after randomisation.

| ITI | CPTSD symptom severity assessed with the International Trauma Interview (ITI), (scale ranging from 0-48, higher scores indicate higher severity) | End of intervention, 9 months after randomisation (and assessed as an exploratory outcome at 18 months after randomisation) |

| SAE | Proportion of participants with at least one serious adverse event (SAE) during the intervention period, assessed via patient medical records by a blinded outcome adjudication committee. SAE is defined as any untoward medical occurrence that resulted in death, was life-threatening, required hospitalisation or prolonging of existing hospitalisation, and resulted in persistent or significant disability or jeopardised the participant. |
| Measure | Description | Time Frame |

| ITQ | Symptoms of ICD-11 complex PTSD, assessed with the International Trauma Questionnaire (ITQ), (a total symptom severity score will be calculated by summing PTDS items (P1-P6) and Disturbances in Self-Organization (items C1-C6) symptoms, yielding a score ranging from 0-48, with higher scores indicating greater CPTSD symptom severity) | 3, 6, and 9 months after randomisation (and assessed as an exploratory outcome at 18 months after randomisation) |

After the results have been published, we aim to make a depersonalised dataset publicly available on e.g. ClinicalTrials.gov and/or the European Union (EU) Zenodo database (https://zenodo.org/). The final choice will reflect which platform(s) that are compliant with current legislation at that time.
