A study published online show that prolonged deployment in the British Armed forces can lead to mental health problems. Increase in the pace of military operations "operational tempo" not only has an adverse effect on the health of the person but also puts his family under tremendous strain.
The UK armed forces have recommended deployment levels called the harmony guidelines, reflecting the need to balance rest and recuperation with deployment. In times of simultaneous major operations, such as those in Iraq and Afganistan, this tool is helpful for monitoring overstretch as a measure of over-commitment.
So a study carried by Professor Roberto Rona and colleagues at Kings College London, set out to assess whether deployments above these guidelines (calculated as 13 months or more in a three year period) have an effect on psychological health.
They studied the number and duration of deployments in the last three years of a random sample of 5,547 regular military personnel. Mental health and alcohol use were assessed using recognised scoring methods.
Other outcomes included intentions to stay in the military and problems at home during and after deployment. All analyses were adjusted for factors such as age, gender, rank, marital status and Service. Further adjustments were made for role in theatre (combat or support), type of deployment (war or peace enforcement operations), and time spent in a forward area in close contact with the enemy.
