The purpose of the current study was investigating the effects of Multi-component cognitive-behavioral group-therapy on insomnia, sleep self-efficacy, dysfunctional beliefs about sleep and four sleep parameters. The population was day-work personnel of Aghajari Oil and Gas Production Company. The sample consisted of 45 employees with insomnia who were selected by multistage random sampling method and assigned to experimental, placebo and waiting list groups. They completed Athens Insomnia Scale, Sleep Log, Perceived Sleep Self-efficacy Scale and Dysfunctional Beliefs and Attitudes about Sleep. The experimental group received 6 sessions of group therapy. The two control groups received no intervention but placebo group was asked to bring their filled sleep log to six meeting sessions for review. The results of MANCOVA and Benferoni post hoc showed that there were significant reductions on insomnia, dysfunctional beliefs about sleep, total time in bed, sleep onset latency and wake after sleep onset. Significant increases were observed on sleep self-efficacy and total sleep time of experimental group, in comparison to two control groups in post-test and follow-up. There were no significant differences between the groups in terms of total time in bed at follow up. No significant differences were found between the two control groups.
