Sample was weighted to ensure it was representative with respect to age, sex, ethnicity, and clinical role. Participants with missing values in outcome scores were excluded for each calculation of the outcome. GHQ-12=12-item General Health Questionnaire. PTSD=post-traumatic stress disorder. PCL-6=6-item Post-Traumatic Stress Disorder checklist. CAPS-5=Clinician-Administered PTSD scale for DSM-5. CIS-R=Clinical Interview Schedule-Revised.
