Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention used in this study will be the Moral Injury Treatment for Refugees (MIT-R). The aim of this clinical study is to assess if MIT-R is effective in reducing post-traumatic stress disorder symptoms, reducing negative moral emotions (i.e., anger, shame, and guilt) and increasing social functioning in a group of Arabic, Dari, Farsi and English-speaking refugees. MIT-R was developed in consultation with refugee community leaders and service providers. We drew on evidence-based strategies from existing interventions focused on moral injury, anger, guilt and shame, as well as interventions adapted to the refugee context. This study will utilise a randomised multiple baseline case series design, where participants will be randomised to a baseline length of 4, 6, or 8 weeks before receiving the intervention. MIT-R comprises 12 weekly sessions (1.5 hours each session) for individuals and will be delivered online via Zoom. This intervention comprises four phases: Psychoeducation- in this phase, participants’ symptoms are normalised and participants learn about the psychological effects of traumatic events and morally injurious events for refugees; Narrative Exposure Therapy: in this phase, participants’ autobiographical narrative is constructed, key morally injurious/traumatic events are identified and processed. Narrative Exposure Therapy is the leading evidence-based trauma-focused intervention for PTSD in refugees and has been evaluated in more than 20 studies; Culturally-Informed Cognitive Therapy: In this phase, moral injury appraisals are situated within participants’ personal and cultural moral frameworks and addressed using evidence-based cognitive techniques for reducing negative emotions; Reconnecting with Community: In this phase, functional implications of moral injury appraisals are identified; participants re-connect with important relationships and cultural values; an action plan is developed to facilitate increased future engagement in life and with community, consistent with existing treatments of moral injury in non-refugee populations.

The treatment manual for MIT-R has been adapted to suit Arabic, Dari, Farsi and English-speaking refugees. Psychologists trained in the delivery of MIT-R and Narrative Exposure Therapy will facilitate the interventions. Trial therapists will undergo specific training in delivering all treatment sessions including the use of a protocol-based treatment manual.

The following protocols will be followed to ensure close therapeutic compliance with the treatment manual: (i) therapists will receive regular clinical supervision; (ii) participant attendance will be recorded by the clinician as part of routine care; (iii) the treatment manual will be used in all treatment sessions; (iv) with participant consent all treatment sessions will be video recorded and 15% will be randomly selected and rated for therapist adherence to the manual.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be randomly allocated to baseline length using computer software. Allocation to baseline length will be conducted after participant eligibility has been confirmed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Block randomisation methods will be used via computer software to ensure an equal amount of participants are assigned to each baseline length (4, 6 or 8 weeks).

Intervention assignment
Other
Other design features
A randomised, multiple baseline design will be used in this study, where participants are randomly allocated to a baseline length of either 4, 6, or 8 weeks. Assessments will be completed at Baseline (before baseline length randomisation), Pre-treatment (after baseline length completion), Post-treatment and follow-up (3 months after treatment is complete). During baseline and treatment phases, weekly symptom questionnaires (PTSD, anger, shame, guilt, depression and social wellbeing) will be administered.

Efficacy
Statistical methods / analysis
The total sample size for the project is 12 participants from a refugee background who speak either Arabic, Dari, Farsi or English, comprising 10 participants who undertake the intervention, and allowing for two who may either not show a stable pattern of PTSD during the baseline phase or drop-out during the baseline phase. If more than two participants either fail to show a stable pattern of PTSD during the baseline phase, or drop-out during the baseline phase, we will recruit more participants until 10 complete the baseline phase.

This sample size is sufficient to meet the research aims and answer the research questions because 10 participants would provide 80% power to detect a large (d = 1.0) treatment effect at alpha = 0.05 for a paired-samples t-test performed on pre- to post-treatment scores. Other studies that have implemented analogous exposure-based and cognitive techniques to reduce PTSD symptoms in refugees have found large within-subjects effects (d = 1.5 to 3.0). Furthermore, other studies have demonstrated that 10 participants with a minimum of 4 datapoints each provides adequate power to determine the effectiveness of an intervention using a case series design. We will only include participants in the final analyses who met diagnostic criteria for PTSD at both the Baseline and Pre-treatment assessments.

In this study, multi-level modelling and mixed-effects regression analyses will be used to evaluate longitudinal trajectories of symptom change and compare slopes of changes in moral injury appraisals and outcomes during baseline and treatment phases. We will also undertake clinically significant change analyses to investigate the proportion of participants who show reliable and clinically significant change at post-treatment and follow-up, relative to pre-treatment.
