Abstract :
The present study aimed to investigate the effectiveness of mindfulness training on the improvement of symptoms, sleep quality, and cognitive functions of individuals with chronic insomnia. This semi-experimental study was conducted using a pre-test, post-test, three-month follow-up design with a control group. The statistical population included all individuals with chronic insomnia who visited counseling centers in Tehran in 2024. From this population, 30 participants were selected through convenience sampling and were randomly assigned to two groups: experimental (15 participants) and control (15 participants). The intervention consisted of 8 weekly sessions of 90-minute mindfulness training, implemented in a group format at a well-equipped counseling center. The research instruments included the Pittsburgh Sleep Quality Index (Buysse, 2010) and the Cognitive Functions Questionnaire (Najati, 2013), After completing the questionnaires during pre-test, post-test, and follow-up stages, the obtained data were analyzed using repeated measures ANOVA. The results revealed that mindfulness training significantly improved the symptoms, sleep quality, and cognitive functions of individuals with chronic insomnia in the experimental group compared to the control group (p<0.05). The findings indicate that mindfulness can serve as an effective and sustainable non-pharmacological approach, playing a crucial role in improving the psychological and cognitive status of these individuals.
