Cognitive behavioral therapy for insomnia (CBT-I) has been the 'gold standard' for the treatment of insomnia. There is a need to increase access to treatment, particularly for patients in more rural locations where providers may be scarce. One solution is to utilize telemedicine which is "the use of electronic communications to provide and support health care when distance separates the provider from the patient." So the purpose of the study is to determine if receiving CBT-I by video teleconferencing works just as well as in-person treatment.
