Clinical Trial Summary

The primary aim of this study is to investigate the effect of Internet-delivered Acceptance and commitment therapy for PTSD and comorbid chronic pain. First, a pilot study (no randomization; N=10) will be conducted to test the intervention and assessment procedures. This will be followed by a randomized controlled trial with waitlist control. The participants will go through an active internet-based ACT treatment focused on education about PTSD, value-based exposure for the traumatic memory and avoided situations, and behavior change through exercises targeting the processes mindfulness, cognitive defusion and acceptance. The treatment is delivered on a safe internet platform. Participants have planned telephone contact with their assigned psychologist 3 times during the program and can also contact their psychologist via a message system in the platform and expect answer within 48 hours.

Description:

Objective: The primary aim of this study is to investigate the effect of Internet-delivered Acceptance and commitment therapy (iACT) for PTSD and comorbid chronic pain.

Sample size: 10 participants.

Trial design: All participants are offered treatment. Participants are recruited from the Pain Rehabilitation Unit at Skåne University Hospital. The unit is a government supported, regional specialist center focused on assessment and treatment of chronic pain and related disability.

Assessments: Baseline and post treatment (2 weeks after treatment) assessments will be conducted by an assessor who is trained to administer the study measures. Self-report measures will also collected at this time, post treatment (2 weeks after treatment) as well as during a 3-month follow up.

Assessment includes:

Pre-and post assessment: Assessors will collect demographic information, self-report measures, and trauma history. During the pre- and post-assessment the Clinician-Administered PTSD Scale for DSM-5 will be administered to establish PTSD whether participants met the DSM-5 criteria for PTSD.

During the pre-assessment the Mini International Neuropsychiatric Interview 5.0 (MINI) will be administered to detect the presence of other comorbid disorders and assess inclusion criteria and rule out exclusion criteria.

Post-treatment exit interview: At the post-assessment, the assigned assessor will ask participants about their satisfaction with and experience of the program, what they found helpful or unhelpful and suggestions for future improvements.

During treatment: During treatment the treatment credibility scale will be administered to assess the patients' perceptions of how credible the treatment is following the introduction of the treatment rationale and the main treatment components (included in the internet program).

Safety parameters: As a mean to monitor safety and progress participants complete two self-report measures within the program (PTSD Checklist for DSM-5 [PCL-5] and Hospital anxiety and depression scale [HADS] twice during the program and the therapist can follow these scores. In addition, participants can report any adverse events during treatment, at post treatment and follow-up assessment.

Data collection: Self-report measures will be mailed to participants

Main statistical analysis: Between-group estimates on outcome will be conducted using repeated measurements. The analyses will be conducted using intention to treat principles and post hoc comparisons.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	PTSD diagnostic status as measured by the Clinician-Administered PTSD Scale (CAPS)	(changes between assessments) The scale assesses the presence of the DSM-5 PTSD criteria A-J.	Baseline, two-week-post treatment.
Primary	PTSD symptom severity as measured by the the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5) and the Life Events Checklist (LEC-5)	(changes between assessments) The scale ranges from 0-80 and higher sores indicate greater severity of PTSD symptoms.	Baseline, two-week-post treatment, 3 month-follow-up.
Secondary	Anxiety and depression as measured by the Hospital Anxiety and Depression Scale (HADS)	(changes between assessments) The subscales range from 0-21 and higher scores corresponds to greater severity of depression/anxiety.	Baseline, two-week-post treatment, 3 month-follow-up.
Secondary	Psychological inflexibility as measured by the Psychological Inflexibility in Pain Scale (PIPS)	(changes between assessments) The scale ranges from 12-84 and higher scores corresponds to greater psychological inflexibility.	Baseline, two-week-post treatment, 3 month-follow-up.
Secondary	Acceptance as measured by the Chronic Pain Acceptance Questionnaire-8 (CPAQ-8)	(changes between assessments) The scale ranges from 0-48 and higher scores corresponds to greater acceptance.	Baseline, two-week-post treatment, 3 month-follow-up.
Secondary	Posttraumatic Cognitions as measured by the Posttraumatic Cognitions Inventory (PTCI)	(changes between assessments) The scale ranges from 33-231 and higher scores corresponds to greater endorsement of trauma-related thoughts and beliefs.	Baseline, two-week-post treatment, 3 month-follow-up.
Secondary	Pain interference as measured by the Multidimensional Pain Inventory (MPI)	(changes between assessments) The scales ranges from 0-6 and higher scores corresponds to greater pain interference.	Baseline, two-week-post treatment, 3 month-follow-up.
Secondary	Pain intensity as measured by the Numerical Rating Scale (NRPS)	(changes between assessments) The scale ranges from 0-10 and higher scores corresponds to greater pain intensity.	Baseline, two-week-post treatment, 3 month-follow-up.
Secondary	Pain catastrophizing as measured by the Pain Catastrophizing Questionnaire (PCS)	(changes between assessments) The scale ranges from 0-52 and higher scores represent greater pain catastrophizing.	Baseline, two-week-post treatment, 3 month-follow-up.
Secondary	Perceived health as measured by the RAND-36 Measure of Health-Related Quality of Life (RAND-36)	(changes between assessments) Each subscale is directly transformed into a 0-100 scale where higher scores correspond to greater levels on that specific subscale.
