There are a number of meta-analyses that summarize the literatures for both benzodiazepines (BZs) and benzodiazepine receptor agonists and for cognitive behavioral therapy for insomnia (CBT-I). The DSM-IV differentiates between primary insomnia, in which the sleep disorder occurs as an isolated condition, and secondary insomnia, in which it occurs in the context of another disorder.
