STUDY OBJECTIVES
Insomnia is a common problem that affects 9% to 15% of the population chronically. The primary objective of this study was to demonstrate that 8 weekly sessions of sleep restriction therapy of insomnia combined with hypnotic reduction instructions following a single session of sleep hygiene education would result in greater improvements in sleep and hypnotic use than sleep hygiene education alone.

METHODS
Forty-six men and women were recruited from a sleep medicine practice and randomly assigned to sleep hygiene education plus 8 weeks of sleep restriction and hypnotic withdrawal (SR+HW; n = 24), or a sleep hygiene education alone (SHE; n = 22) condition. Pre-randomization, all patients received a single session of instruction in good sleep habits (sleep hygiene education).

RESULTS
The SR+HW condition had greater improvements in hypnotic medication usage, sleep onset latency, morning wake time, sleep efficiency, and wake time after sleep onset (trend), than the SHE condition. Continued improvement was seen in TST in the SR+HW group at 6-month follow-up, and gains on all other variables were maintained at 6- and 12-month follow-up.

CONCLUSIONS
These results provide evidence that more intensive treatment of insomnia (i.e., 8 sessions of SR+HW plus hypnotic withdrawal instructions) results in better outcomes than SHE alone.
