Background: Insomnia, as one of the most common sleep disorders, is influenced by cognitive and emotional factors and can have extensive consequences for individuals’ mental health, daily functioning, and quality of life. In this regard, cognitive avoidance, as a maladaptive strategy for avoiding distressing thoughts and emotions, and obsessive beliefs, through increasing worry, inflated responsibility, and mental control, may play an important role in exacerbating sleep problems. Therefore, examining the role of these variables in predicting insomnia is of considerable research and clinical importance.
Aims: The present study aimed to predict insomnia based on cognitive avoidance and obsessive beliefs.
Methods: The present study was applied in terms of purpose and descriptive-correlational in terms of method. The statistical population included all individuals referring to sleep disorder centers in Tehran. Using convenience sampling, 300 participants were selected as the study sample. Data were collected using the Insomnia Questionnaire developed by Morin (1993), the Cognitive Avoidance Questionnaire developed by Sexton and Dugas (2009), and the Obsessive Beliefs Questionnaire developed by the Obsessive-Compulsive Cognitions Working Group. The data were analyzed using Pearson correlation coefficient and simultaneous regression analysis through SPSS version 22.
Results: The findings showed that the multiple correlation coefficient was 0.67, indicating a relatively favorable relationship between the predictor variables and insomnia. Moreover, the coefficient of determination indicated that cognitive avoidance and obsessive beliefs together explained 45% of the variance in insomnia. The results of regression coefficients also showed that cognitive avoidance, with a standardized coefficient of 0.25, and obsessive beliefs, with a standardized coefficient of 0.307, positively and significantly predicted insomnia.
Conclusion: Based on the findings, it can be concluded that cognitive components, particularly maladaptive patterns in dealing with thoughts and obsessive beliefs, play a considerable role in explaining insomnia. Therefore, addressing the reduction of cognitive avoidance and the modification of obsessive beliefs may be useful in the assessment, prevention, and development of psychological interventions for individuals with insomnia. These results emphasize the necessity of applying cognitive-behavioral approaches in the management and treatment of insomnia.
