Summary
Brief summary
Military personnel returning from overseas deployment often suffer from sleep difficulties. Demanding and altered working hours, challenging environmental conditions, high work tempo, and altered interpersonal and support environments contribute to disturbed sleep during operations. If left untreated, sleep difficulties can lead to poorer mental health outcomes; in fact, sleep complications may become a chronic health issue. The research will evaluate the effectiveness of two treatments. Cognitive Behavioural Therapy for Insomnia (CBT-i) and Bright Light Therapy (BLT) for improving sleep and mental health will be trialed in a sample of 40 ADF personnel.
