# Evaluation of SHAPE cognitive therapy coaching for PTSD and depression symptoms in healthcare workers repeatedly exposed to trauma

## TL;DR

A telephone-based cognitive therapy coaching program significantly reduced PTSD and depression symptoms in healthcare workers during the pandemic, with improvements lasting up to three months.

## Contribution

The study introduces and evaluates a tailored cognitive therapy coaching intervention for healthcare workers with PTSD and depression.

## Key findings

- Reliable recovery rates for PTSD and depression increased from 14.6% and 15.8% to 77.1% and 64.3% after the intervention.
- Improvements in PTSD, depression, and anxiety scores remained below clinical thresholds at the three-month follow-up.
- The intervention led to sustained improvements in sleep, resilience, and wellbeing.

## Abstract

Healthcare workers are at increased risk of posttraumatic stress disorder (PTSD), depression and generalised anxiety disorder. Evidence-based interventions tailored to this workforce are limited. We developed and evaluated a telephone-based cognitive therapy coaching intervention targeting PTSD and depression. One hundred three healthcare workers seeking support during the COVID-19 pandemic completed measures at baseline, after three-week symptom monitoring, following six-week coaching, and at three-month follow-up. Sixty-five participants met criteria for probable PTSD (PCL-5 ≥ 32) or probable depression (PHQ-9 ≥ 10), and 38 experienced subthreshold symptoms. For PTSD (PCL-5) and depression (PHQ-9), reliable recovery rates increased substantially from symptom monitoring (PTSD: 14.6%; depression: 15.8%) to intervention (PTSD: 77.1%; depression: 64.3%), with sustained recovery at three months (68.8% and 52.6%, respectively). Overall, rates of reliable improvement increased from 41.1% to 65.8% for PTSD and from 20.0% to 63.1% for depression during intervention, with gains maintained at follow-up (72.2% and 56.0%, respectively). Mean PTSD, depression and anxiety (GAD-7) scores fell below clinical thresholds post-intervention and remained below at follow-up. Intervention-specific effects were observed for sleep, resilience, and wellbeing, with sustained improvements at follow-up. Cognitive therapy coaching is a promising intervention for healthcare workers with PTSD and depression symptoms. A randomised controlled trial is warranted.
