The present paper reviews the basic concepts of insomnia, protocol and trouble shooting in the sleep restriction therapy (SRT) and discusses the potential of SRT intervention in adolescent students suffering from sleep problems, such as delayed sleep phase disorder and irregular sleep habits. SRT was originally developed by Spielman et al., using a protocol of time-in-bed restriction, for improving chronic insomnia in middle-aged and older adults, and today it is known as an effective component of cognitive behavioral therapy for insomnia (CBT-I). The number of studies on CBT-I has remarkably increased during the last fifteen years, but few attempts to improve poor sleep of adolescent students using SRT-combined intervention have been made. Adolescents differ from the general adult population in terms of developmental stage, life style and sleep schedules, and further research seems to be needed to establish an evidence base for the effectiveness of SRT intervention in their sleep problems.
