Plain English Summary

Background and study aims
Frontline health and social care staff are routinely exposed to potentially traumatic events as part of their jobs. Coupled with occupational pressures, such as irregular shift patterns, and understaffing, the cumulative effects of such stress elevate the risk of developing post-traumatic stress disorder (PTSD) and major depression. In addition to experiencing work-related trauma, previous studies have discovered that many health and social care workers experience trauma outside of work, making them a vulnerable population to experiencing PTSD and other mental illnesses. It is therefore important that psychological therapies are readily and easily available for health and social care workers who suffer from such disorders to ensure that their mental health is taken care of and allow them to continue working.
SHAPE, originally funded by the University of Oxford COVID Research Response Fund, is a brief, accessible, remotely delivered intervention that targets cognitive processes and behaviours that maintain PTSD and depression, specifically rumination, unwanted memories, avoidance, and low mood. Pilot work demonstrated that SHAPE coaching achieved clinically significant change in PTSD and depression symptoms within 6 weeks compared to little change achieved during a 3-week monitoring phase. Of the healthcare workers who were diagnosed with PTSD in the study, 91.5% achieved reliable recovery with SHAPE and 71.4% achieved reliable recovery from major depressive disorder. However, due to the design of the pilot study, it is unclear whether the clinical improvements seen with SHAPE are associated with the intervention or with the passage of time.
This study aims to evaluate SHAPE using a gold standard method to establish whether or not the intervention leads to clinical improvements in PTSD and major depressive disorder, and is cost-effective.

The study aims to answer the following questions:
1. Does the intervention lead to recovery from PTSD and depression?
2. Is the reduction in symptoms during the intervention period greater than symptom change during an 8-week wait period?
3. Is the intervention effective, acceptable, and accessible to health and social care staff?
4. Does the intervention offer good value for money?

Who can participate?
Patient-facing health and social care workers (i.e., doctors, nurses, paramedics, care workers, occupational therapists, psychologists, physiotherapists, speech and language therapists, etc.) who are 18 years of age and older and have PTSD or major depression as their primary disorder.

What does the study involve?
Participants’ symptoms of PTSD and depression are assessed using self-report measures and clinician-administered assessments. If a participant meets eligibility requirements, they are randomly allocated to receive the SHAPE intervention immediately or after 8 weeks (waitlist). The self-report and clinician-administered assessments are repeated at 8 weeks (post-intervention/waitlist), and 6 months to assess for symptoms of PTSD and depression. The SHAPE intervention involves completing approximately six coaching sessions over the course of 8 weeks (about one call per week) with a trained coach who specialises in PTSD and depression. Coaching sessions are conducted over the telephone and last about 40-60 minutes. In addition, participants are asked to complete brief weekly questionnaires that assess for changes in PTSD and depression. Participants are also assigned optional homework in the form of online computer modules after each session to consolidate learning.

What are the possible benefits and risks of participating?
All participants will have the option to access the SHAPE intervention during the trial. Participation could lead to recovery from PTSD and depression as well as improvements in participants' resilience and mental well-being.
Some of the questions in the questionnaires are sensitive and may trigger temporary feelings of distress. However, participants will have the support of their well-being coach, and the research team is also available to offer support if needed.

ConditionPost-traumatic stress disorder and major depression in patient-facing health and social care professionals
InterventionCurrent interventions as of 05/04/2024:
Interested participants will be directed to the study's online information sheet and consent form. After reading the information sheet, if a participant is still interested in the trial, they will complete the following online consent form and be sent two screening questionnaires over email to assess for PTSD and depression (PTSD Checklist for DSM-5 [PCL-5] and Patient Health Questionnaire 9 [PHQ-9]). If the participant scores 20 or above on the PCL-5 for PTSD or 10 or above on the PHQ-9 for depression scale, they will be invited to take part in a telephone assessment. The telephone assessment will be conducted by an independent blinded assessor trained in administering the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) Structured Clinical Interview for DSM-5 (SCID-5). The assessor will conduct the SCID-5 assessment for both depression and PTSD with the participant. If a diagnosis* is made for either PTSD or depression the participant will be sent a second online consent form to take part in the trial. (*To ensure inter-rater reliability in SCID-5 diagnoses and prevent interviewer drift, the lead researchers will double-code a random selection of 20% of the telephone interviews over the course of the trial. In addition, the lead researchers will screen the first five interviews of each assessor for quality control.)

After receipt of the second consent form, an independent researcher separate from the core research team will randomly allocate the participant to either the intervention group or the waitlist group using a computer software program called Minim. This program randomly assigns participants using a minimisation method under our prognostic factors of MDD severity high/low on the PHQ-9 (median split 15), an absence or presence of PTSD using the DSM-5 SCID-5, and time since trauma (before or after 18 months).

Following randomisation, all participants will be sent a set of baseline questionnaires via email and receive a brief, standardised welcome call (10 minutes) with their assigned coach. Coaches will be trained mental health professionals/students who have completed the SHAPE training, had two successful training cases and attend weekly supervision sessions.

Participants assigned to the intervention group will begin SHAPE coaching with their assigned coach 1 week after completing their baseline questionnaires and welcome call. Participants will have approximately six SHAPE coaching sessions over the course of 8-weeks (approximately 1 session per week, factoring in holidays, time off work, and sick leave). Some participants may require an extra few sessions depending on the case complexity. Coaching sessions will take place over the telephone and last approximately 40-60 minutes. Participants will also complete a weekly set of online questionnaires, sent at the end of the week that they will need to complete before their weekly coaching session to track symptoms of PTSD and MDD and inform their coaching session. At four weeks (mid-intervention) participants will complete an extended set of online questionnaires to track for hypothesised mediators. At post-intervention (approximately 8 weeks), participants will complete a longer set of questionnaires and have another SCID-5 telephone assessment to assess for PTSD and depression. After 6 months, participants will receive a final set of questionnaires and have a final SCID-5 telephone assessment with an assessor who is blinded to the trial arm.

Participants assigned to the waitlist group will start the trial with a waiting period of 8 weeks with no contact from their assigned coach after their initial welcome call. Mid-way through the waiting period (at 4 weeks) participants will receive the same set of extended questionnaires as the intervention group to track symptoms of PTSD and MDD, risk, and hypothesised mediators. At the end of the 8-week waiting period, participants will be sent the same longer set of online questionnaires as the intervention group and have a SCID-5 telephone assessment to re-assess for PTSD and depression. If a participant is still diagnosed with PTSD or depression and wishes to continue with the trial and have SHAPE coaching, they will begin the SHAPE intervention in 1-2 weeks at a time that suits them. Participants who choose to have the SHAPE intervention will follow the same process as the intervention group and be sent weekly online questionnaires, an extended 4-week set of online questionnaires, a longer set of post-intervention questionnaires, and a post-intervention SCID-5 telephone assessment. After 6 months participants in the waitlist group will be sent a final set of online questionnaires and have a SCID-5 telephone assessment.

After completing the intervention, a purposive sample of participants will also be invited to attend an online interview to collect PROM's information about the accessibility, acceptability, and overall satisfaction of the SHAPE intervention.
