This study aimed to investigate the effectiveness of Cognitive-Behavioral Therapy for Insomnia (CBT-I) in improving sleep quality and reducing  insomnia severity among the afflicted patients. Methods: This was a semi-experimental study with a pre-test, post-test, and follow-up design and control group. The statistical population included all patients visiting the Sleep Disorder Clinic of Rasoul Akram Hospital and two private psychiatric clinics, selected using convenience sampling in Tehran in 2020. Twenty out of 60 patients with insomnia disorder, diagnosed based on the Diagnostic and Statistical Manual for Insomnia, were randomly selected using a lottery method. The participants were divided into the experimental and control groups. In the cognitive-behavioral group, each participant individually received a 6-week treatment intervention. All participants in both groups were evaluated at the beginning of the treatment, at the end of the treatment, and one month after the treatment. The Pittsburgh Sleep Quality Index (PSQI) and  Insomnia Severity Index (ISI) were used for data collection. Results: The results showed a significant between-group difference in the scores of sleep quality and insomnia severity at post-test stage (p<0.05). Moreover, the follow-up test results suggested the stability of the effect of treatment interventions on sleep quality and insomnia severity among the experimental and control groups relative to their pre-test scores (p<0.05). Conclusion: The results indicated that CBT-I could improve sleep quality and insomnia severity in afflicted patients.}, keywords = {Cognitive-behavioral therapy for insomnia (CBT-I),sleep, Sleep initiation and maintenance disorders}, url = {http://www.jimc.ir/article_143939.html}, eprint = {http://www.jimc.ir/article_143939_08ab955a92f91883b997634a73e1de30.pdf} }
