Mental Health

The air service medical laboratory reckoned that 80% of groundings of aircrew were due to nervous disorders, and 50% of pilots developed serious neuroses during their tour of duty.

Air crew tended to suffer from "nerves" or neurasthenia, which would probably be called ombat Stress Reaction today - relatively few from "shell shock". This was caused by the combination of long hours flying under stress, high likelihood of death, plus the cold and lack of oxygen, especially as planes flew ever higher.

From Trauma and Recovery by Judith Herman:
Mental breakdowns represented 40% of British battle casualties(all forces?). Military authorities attempted to suppress reports of psychiatric casualties because of their demoralizing effect on the public.
Initially, the symptoms of mental breakdown were attributed to a physical cause. Psychologist Charles Myers, who inspected some of the first cases, attributed their symptoms to the percussive effectsof exploding shells, and called the disorder "shell shock".
When it was found to be a mental rather than physical issue, traditionalists put it down to poor moral character. A soldier should glory in war and betray no sign of emotion. Certainly he should not succumb to terror. A soldier with a medical neurosis was a "moral invalid", at best a constitionally inferior human being, at worst a malingerer and a coward. Some military authorities said they should be court martialed or dishonourably discharged, rather than given medical treatment. Psychiatrist Lewis Yealland treated them with increasing electric shocks until their symptoms went away.
Progressive psychologists such as W.H.R.Rivers wanted to treat on psychological lines. He created a safe environment where people could talk through their experiences and fears, until fit to return to the battle.
