Internet-Based Cognitive Behavioral Therapy for Insomnia in Persian-Speaking Adults

This study will test whether an internet-based cognitive behavioral therapy for insomnia (ICBT-I) delivered through the Persian-language web program "Omid" can improve sleep in Persian-speaking adults with insomnia. Participants will be adults who have problems falling or staying asleep and meet diagnostic criteria for insomnia. Those who are eligible will be randomly assigned to either receive access to the Omid web-based CBT-I program or to a wait-list control group that will receive usual care during the study period. The Omid program provides weekly online modules with educational videos and texts about sleep and insomnia, sleep hygiene, stimulus control, sleep restriction, and cognitive techniques to manage unhelpful thoughts about sleep. Participants will complete questionnaires about insomnia severity, sleep quality, and daytime sleepiness before starting the program, after finishing the intervention, and at follow-up. The main goal is to see whether the Omid ICBT-I program reduces insomnia symptoms and improves overall sleep quality compared with the wait-list control group.
