NCT04394832

Brief Summary

This research study was designed to investigate the use of a simple cognitive task for decreasing the number of intrusive memories of traumatic events experienced by refugees and asylum seekers with a diagnosis of Post-traumatic Stress Disorder (PTSD) currently living in the UK. The intervention included a memory reminder cue, a 10-minute time gap and then around 20 minutes playing the mobile phone game Tetris, using mental rotation instructions. The study had a multiple baseline case-series design (AB), with a randomised duration of baseline length up to three weeks. Thus, participants completed a no-intervention phase of up to three weeks, followed by an intervention phase. Please see the intervention section for more details about the intervention sessions. Follow ups were conducted after each week to monitor the frequency of intrusive memories of trauma in a pen-and-paper diary. It was predicted that participants would report fewer intrusive memories after receiving the intervention than in the preceding baseline phase.

Outcome Measures

Primary Outcomes (1)

  • Frequency of intrusive memories

    Number of intrusive memories of traumatic events recorded by participants in a pen and and paper diary.

Secondary Outcomes (6)

  • Concentration

    Baseline and 2-weeks post-intervention

  • Social and Occupational Activity Tally (SOAT)

    Baseline and 2-weeks post-intervention

  • Dissociation

    Baseline and 2-weeks post-intervention

  • Post-Traumatic Stress Disorder (PTSD) Checklist for Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) (PCL-5)

    Baseline and 2-weeks post-intervention

  • Patient Health Questionnaire (PHQ-9)

    Baseline and 2-weeks post-intervention

  • +1 more secondary outcomes

Other Outcomes (2)

  • Self-Guided Intervention Adherence Questionnaire

    Intervention weeks 2-5, 1 week post-intervention and 2 weeks post-intervention

  • Feedback Questionnaire

    1-week post-intervention.

Study Arms (1)

Baseline phase, followed by intervention phase

EXPERIMENTAL

Within the baseline phase, measurements of the primary outcome measure (frequency of intrusive memories of trauma) were collected in a pen-and-paper diary for up to three weeks (dependent on baseline length). Individual baseline phases will be used as control periods. In the intervention phase the participant was offered around five intervention sessions with a researcher. Each session the participant chose which intrusive memory they would like to focus on and the cognitive task was completed. The intervention included a memory reminder cue, a 10-minute time gap and then around 20 minutes playing the mobile phone game Tetris, using mental rotation instructions. Participants were given instructions to continue to use the technique self-guided in the subsequent week. Measurements of the primary outcome measure (frequency of intrusive memories of trauma) were collected in a pen-and-paper diary.

Behavioral: Brief cognitive intervention

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • are on the wait list for treatment (trauma focused therapy) at Woodfield Trauma Service
  • aged 18-65
  • have experienced intrusive memories in the past two weeks, as assessed by scoring 1 or above on question 1 of the PCL-5
  • are able to communicate with the researcher, with or without an interpreter
  • have a fixed abode. This is operationalised as having a current address (including B\&B or open access hostel) and evidence indicating that the person is likely to have a reliable address throughout the study. This is necessary to avoid sample attrition.
  • can commit to attending regular appointments and keeping an intrusion diary throughout the duration of the study.

You may not qualify if:

  • a current diagnosis of schizophrenia or bipolar disorder type 1
  • Intelligence Quotient (IQ) \< 80
  • acute suicide risk
  • substance dependence
  • have been unable to complete the routine questionnaires given to new patients in the service at assessment
