Few Armed Forces personnel seek help for mental health disorders and novel approaches will be needed to encourage personnel at risk of PTSD, anxiety and alcohol abuse to seek treatment, suggests a new study. A trial testing a potential post-deployment screening program for UK Armed Forces personnel, based on a computerized assessment and tailored mental health advice, found it was not effective in reducing symptoms of mental health disorders or encouraging personnel to seek help, compared to the general mental health advice which is the standard of care in the UK military.
