Behavioral treatment of insomnia: a clinical case series study.

There is substantial experimental evidence that behavioral treatment of insomnia produces significant clinical improvement and that treatment gains tend to be maintained over time. Less clear is whether behavioral treatment is effective as it is plied in clinical settings. In this clinical case series study, we evaluated 47 patients with primary insomnia. It was found that patients were, on average, 43% improved. This average corresponded to a 65% reduction in sleep latency, a 46% decrease in number of awakenings per night, a 48% reduction in wake time after sleep onset, and a 13% increase in total sleep time. These results suggest that behavioral treatment for insomnia is as effective in clinical settings as it is as under clinical trial conditions.
