Brief Summary

Complex Post traumatic Stress Disorder (CPTSD) is now recognized as a separate trauma-based psychological condition to PTSD. CPTSD is a broader diagnosis that includes the core PTSD symptoms (re-experiencing in the here and now, avoidance, and sense of current threat) plus an additional set of symptoms that are collectively referred to as 'disturbances in self-organisation' (DSO). DSO symptoms capture pervasive psychological disturbances that are associated with traumatic exposures and that are distributed across three clusters: difficulties in affect regulation (AR), negative self-concept (NSC), and disturbances in relationships (DR). There are no effective interventions for CPTSD. It is therefore of paramount important to identify effective interventions to treat veterans with CPTSD. The present study will be one of the first to investigate the effectiveness of a novel, modular intervention for CPTSD. Enhanced Skills Training in Affective and Interpersonal Regulation (ESTAIR) is a person-centered intervention that involves targeting the symptoms of CPTSD clusters sequentially using concrete modules (i.e., specific number of sessions targeting specific clusters of symptoms). The overall aim of this study is to establish the feasibility, acceptability and preliminary effects of ESTAIR in treating CPTSD. To achieve these aims, the investigators will conduct a pilot randomised controlled trial (RCT), with a sample of 60 military veterans meeting the diagnostic criteria for CPTSD, and with two treatment arms: ESTAIR vs. a treatment-as-usual (TAU) condition.

Outcome Measures

Primary Outcomes (3)

  • Retention rate at the end of treatment

    Percentage of clients completing intervention and completing outcome measures at the end of treatment.

    Post-treatment (week 25)

  • Retention rate at 3-months follow up

    Percentage of clients completing intervention and completing outcome measures at 3-months follow up.

    3-months follow-up (week 37)

  • Change in symptoms of CPTSD on the International Trauma Questionnaire (ITQ) from baseline to end of treatment to 3-months follow up

    The ITQ (Cloitre et al., 2018) is a validated questionnaire assessing PTSD and complex-PTSD (CPTSD). Six items represent the three clusters of PTSD (re-experiencing, avoidance and sense of threat), while another six items represent the three clusters reflecting disturbances in self-organisation (DSO) (AD: affective dysregulation; NSC: negative self-concept; and DR: disturbances in relationships. The remaining items assess functional impairment relating to symptoms of PTSD (3 items) and DSO (3 items). Items are scored using 5-point Likert scales ranging from 0 (not at all) to 4 (extremely), indicating how much a symptom has affected them in the past month. A diagnosis of CPTSD required a diagnosis of PTSD (at least one symptom of each of its three clusters as well as functional impairment) in addition to endorsement of at least one symptom of each of the three DSO clusters plus functional impairment.

    Baseline, end of treatment (week 25) and 3-months follow up (week 37)

Secondary Outcomes (5)

  • Change in symptoms of depression on the 9-item Patient Health Questionnaire (PHQ-9) from baseline to end of treatment to 3-months follow up

    Baseline, end of treatment (week 25) and 3-months follow up (week 37)

  • Change in symptoms of generalised anxiety on the 7-item Generalised Anxiety Disorder Questionnaire (GAD-7) from baseline to end of treatment to 3-months follow up

    Baseline, end of treatment (week 25) and 3-months follow up (week 37)

  • Change in alcohol use on the 3-item (AUDIT-C) from baseline to end of treatment to 3-months follow up

    Baseline, end of treatment (week 25) and 3-months follow up (week 37)

  • Change in medically unexplained symptoms on the 15-item Patient Health Questionnaire-15 (PHQ-15) from baseline to end of treatment treatment to 3-months follow up

    Baseline, end of treatment (week 25) and 3-months follow up (week 37)

  • Outcome on the single item Friends and Family Test (FFT) at end of treatment.

    End of treatment (week 25)

Other Outcomes (5)

  • Experience of potentially traumatic life events on the Life Events Checklist (LEC)

    Baseline

  • Rates of adverse events at end of treatment and 3-months follow up

    End of treatment (week 25) and 3-months follow up (week 37)

  • Change in symptoms of CPTSD on the International Trauma Questionnaire (ITQ) following each module in ESTAIR arm only

    Week 7, Week 13, Week 19, Week 25

  • +2 more other outcomes

Study Arms (2)

ESTAIR

EXPERIMENTAL

ESTAIR (Cloitre et al., 2019) will consist of up to 25 sessions, organized in 4 modules of 6 sessions targeting symptoms of PTSD and disturbances in self-organisation (AD: affective dysregulation; NSC: negative self-concept; and DR: disturbances in relationships).

Behavioral: Enhanced Skills Training in Affective and Interpersonal Regulation

Treatment as usual (TAU)

ACTIVE COMPARATOR

At present, there are no recommended treatments for CPTSD. TAU will consist of a treatment package that could include elements of psychoeducation, symptom-management and trauma-focused cognitive behaviour therapy, resembling established protocols for treating PTSD.

Behavioral: Treatment as usual

Interventions

The first (formulation) session enables linking present difficulties and traumatic events, identifying current issues/concerns, and collaboratively agreeing on the order of modules based on symptom severity and client readiness. The PTSD module provides narrative exposure to the traumatic memories and targets re-experiencing, avoidance and hyperarousal symptoms. The AD module focuses on identifying and labelling feelings, emotion management, distress tolerance, acceptance of feelings and experiencing positive emotions. The NSC module focuses on staying in the present moment and combating dissociation; self-compassion and mindfulness skills; challenging thinking patterns and developing a balanced view of self. The DR module focuses on exploring and revising maladaptive schemas; effective assertiveness; awareness of social context; and flexibility in interpersonal expectations and behaviours displayed in social interactions.

ESTAIR

The first session will involve a mental health assessment by either a psychiatrist or psychologist. A treatment package will be developed based on the information collected during the assessment. Details of the interventions delivered to each participant receiving TAU, which will include elements of psychoeducation, symptom-management and trauma-focused cognitive behaviour therapy, will be recorded.

It was initially intended for the research assistant collecting post-intervention and follow-up outcome measures to be masked to arm allocation. However, it is noted that such masking is not feasible. This is not deemed a risk to the study as outcome measures are self-report measures.

Data collected in this study will be stored for 10 years and will not be made available to other researchers (because of the small sample sizes involved). Summary data will be provided in publications, but the individual data will not be available given the risks this raises with identification of participants. The data will not be shared except for the purposes of audit by Edinburgh Napier University or Combat Stress approved staff.
