Utilising a Constructivist Grounded Theory, phase 1 consisted of 19 interviews with experienced Army mental health clinicians. Phase 2 was a validation exercise conducted with 3 general practitioners. This nurse-led study highlighted that the most common reason given for soldiers’ hospital admission for mental ill health was for a depressive illness, with the majority presenting with multi-factorial problems displayed in numerous ways. The authors suggest that more awareness around military stressors and gender imbalances regarding access and treatment need considering.
