Summary
This study tested whether a brief 4-session version of cognitive-behavioral therapy (CBT) works as well as the standard 6-session version for treating insomnia in veterans. Insomnia is very common among veterans and can harm daily life and health. The study enrolled 15 veterans with insomnia and a mental health condition, measuring sleep quality and daytime function before and after treatment.
