Online cognitive behavioural therapy (CBT) for chronic insomnia is effective in improving insomnia severity, daytime fatigue, and sleep quality, according to a study.
The researchers behind the study claim that online treatment also reduces erroneous beliefs about sleep and pre-sleep mental arousal.
According to the results, 81 percent of treated participants (30 of 37) found at least mild improvement in their sleep after completing the five-week program, including 35 percent (13 of 37) who rated themselves as much or very much improved.
Around 30 percent of members in treatment group, who completed the program, were receiving an additional hour of sleep at the end of the program.
Those who received treatment also developed healthier attitudes about sleep, and were less likely to report having an overactive mind at bedtime.
Principal investigator Dr. Norah Vincent, a psychologist at the University of Manitoba in Winnipeg, Canada, said that they were surprised by the significant results in the absence of any ongoing support from a clinician.
The treatment program consisted of psychoeducation about insomnia, information concerning sleep hygiene, stimulus control instruction, relaxation training, sleep restriction and cognitive therapy.
