Assessment of a Brief Post Traumatic Stress Disorder Intervention for Use in Botswana

The purpose of this study is to culturally adapt a brief psychological intervention for Post-Traumatic Stress Disorder (PTSD) and assess its efficacy, feasibility, and acceptability in a pilot trial. The intervention has been shown to be efficacious among individuals with comorbid severe mental illness (SMI) and PTSD.

The study will be conducted in three phases. The first phase will determine a description of trauma and responses to traumatic experiences among patients with severe mental illness. The first phase of the study will also determine participants' and mental health care providers' perceptions of suitable PTSD interventions in this middle-income context. The findings will then be used to culturally adapt the brief intervention in the second phase. A pilot trial will be conducted in the third phase of the study.

Participants with comorbid SMI and PTSD will be randomized into two groups (n= 20 intervention group, n= 20 control group). Outcomes of the intervention such as the severity of PTSD symptoms, knowledge about PTSD will be assessed at baseline and at different timelines during the study.

This study will fill the knowledge gap on trauma and its consequences among individuals with severe mental illness in Botswana, it will also contribute to the improvement of clinical practice in the management of PTSD and SMI.

About this study

Study participants will be recruited from Sbrana Psychiatric Hospital, the only referral psychiatric hospital in Botswana. The hospital population is representative of the culturally diverse Botswana nation because patients with severe mental illness from the entire country are admitted to the hospital. Forty participants (40) will be recruited and randomized to receive the Brief Relaxation, Education, And Trauma HEaling (BREATHE) intervention or treatment as usual.

The intervention will be delivered by the Principal Investigator who has received training from the intervention developer. Supervision will be provided telephonically.

The BREATHE intervention will be delivered weekly for each participant for a total of three weeks and 4 participants will be enrolled per group resulting in a total of 5 groups. The estimated period of intervention delivery and data collection is therefore expected to last for a period of ~15 weeks.

Outcomes such as anxiety, depressive and PTSD Symptoms, and knowledge about PTSD will be assessed before participants receive the intervention, weekly (following each treatment session), month one and month three after treatment completion. Assessment of feasibility and acceptability will be done at treatment completion with the intervention group. Participants on the control arm will receive outcome measures at the same time points as those receiving the intervention. The investigators will utilize an objective assessment of skin conductance which has been shown to be greater in individuals with PTSD than in individuals without PTSD and similarly increased during a trauma interview in individuals with PTSD compared to individuals who do not have PTSD.

Treatment and study plan

Brief Relaxation, Education And Trauma HEaling

Behavioral

A three-week psychological intervention for PTSD which comprise psychoeducation and breathing retraining to manage anxiety symptoms

Primary outcomes

  1. Post Traumatic Checklist-5

    Time frame: baseline, week 1, 2 ,3,

    Mean Change from Baseline in the severity of PTSD symptoms as assessed with the PCL-5. Total scores for the Post Traumatic Checklist-5 range between 0 and 80 with a cut off score of 33 or higher suggesting the patient may benefit from PTSD treatment. Patients with scores lower than 33 may indicate the patient has sub-threshold symptoms of PTSD

  2. eSense EDA skin conductance device

    Time frame: baseline, week 1, 2 ,3,

    Change in physiological arousal as measured with sensors to assess skin conductance

  3. Mini International Neuropsychiatric Interview (MINI) Plus

    Time frame: baseline, week 3, one month and three months post intervention

    Assessment of symptoms meeting the criteria for PTSD

  4. Consent rates

    Time frame: week 3

    to assess the acceptability of the intervention by dividing the number of participants who meet the criteria for PTSD and meet the inclusion criteria for the pilot trial by the number of those who consent to participate in the trial

  5. Adherence rates

    Time frame: week 3

    to assess acceptability; measured by the total number of sessions attended by the participants and the reasons for non-adherence.

  6. knowledge of PTSD scale (KPTSD)

    Time frame: baseline, week 1, 2 ,3, one month and three months post intervention

    mean difference in the scores obtained in the knowledge of PTSD scale. Higher scores indicate more knowledge of PTSD.

  7. Acceptability of Intervention measure (AIM)

    Time frame: week 3

    Calculation of scores in the Acceptability of Intervention measure. Higher scores indicate greater acceptability

  8. Feasibility of Intervention Measure (FIM)

    Time frame: week 3

    calculation of scores in the Feasibility of Intervention Measure. Higher scores indicate greater feasibility

  9. Patient satisfaction scale

    Time frame: week 3

    calculation of scores in the satisfaction scale. Higher satisfaction with the intervention will be indicated by high scores on the patient satisfaction scale

Secondary outcomes

  1. Patient Health Questionnaire-9 (PHQ-9)

    Time frame: baseline, week 1, 2 ,3, one month and three months post intervention

    Mean Change from Baseline in the severity of depressive symptoms as assessed with the PHQ-9

  2. Clinical Outcomes in Routine Evaluation-Outcome Measure

    Time frame: baseline, week 3, one month and three months post intervention

    Mean difference from Baseline in the severity of psychological distress

  3. Zung self-rating anxiety scale

    Time frame: baseline, week 1, 2 ,3, one month and three months post intervention

    Mean Change from Baseline in the severity of anxiety symptoms as assessed with the Zung anxiety rating scale. Total scores in the Zung self rating scale range from 20 to 80, with scores above 26 indicating severe and extremely severe anxiety.

  4. Post Traumatic Checklist-5

    Time frame: one month and three months post intervention

    Mean Change from Baseline in the severity of PTSD symptoms as assessed with the Post Traumatic Checklist-5. A five points difference in the total score is an indication that a patient has responded to treatment and 10 points has been determined as a minimum threshold for determining whether the improvement has clinical utility
