Self-help intervention delivered via devices

In general, cognitive behavioral therapy for insomnia(CBT-I) is conducted via face-to-face sessions. Recently, several devices have been developed to deliver self-help interventions to patients with insomnia via booklets, computers, telephone, e-mail, or television. In this article, I reviewed an efficacy of these self-help interventions for insomnia. Self-help interventions had a small to moderate positive effect compared with the control group, but was inferior to face-to-face therapy. However, I suggest that these self-help interventions may constitute a useful addition to existing intervention options especially when integrated in a stepped care approach, among individuals with insomnia who live in remote areas.
