CBT has been successfully used to treat insomnia in both men and women, but according to a recent article men tend to seek treatment less often than women. Even when they consult their primary care providers, those providers are often unaware of CBT's effectiveness and may have limited CBT resources to offer their patients. To address this, researchers offered group CBT in the form of 1-day, all-male CBT workshops. The study ran six months, and drew 111 inquiries, some of them self-referred. The researchers noted that roughly half of the participants had not mentioned their insomnia to their primary care providers. In a six-week follow-up, the men "reported significant improvements in their sleep, as well as reductions in their depression." --Read more about CBT for insomnia.
