Acceptance and commitment therapy (ACT) has recently received much attention from therapists working in the field of sleep disorders. However, less attention has been paid to the role of ACT components in sleep problems. To this end, the present study aimed to investigate the role of ACT components in predicting sleep quality and insomnia severity.


This cross-sectional study was conducted on the survivors of a major earthquake (7.3 on the Richter scale in 2017) in urban and rural areas of Kermanshah province (western Iran) 4 years after the earthquake. The data were collected using a questionnaire and data analysis was performed for 1094 people.


The results showed that all six components of ACT are related to sleep quality and insomnia severity. The findings also revealed that ACT processes can account for 19% of sleep quality and 27% of insomnia severity. Moreover, about 35% of the variances in the sleep quality subscales were predicted by the six components of ACT. The results showed the important role of experiential avoidance (i.e., acceptance) in predicting sleep quality and insomnia severity compared to other ACT processes.


Based on the results of the present study, it can be suggested all six processes of ACT are correlated with and predictive of sleep quality and insomnia severity. Further, sleep disorder therapists should take special account of acceptance when working with sleep problems because of the importance of acceptance in predicting sleep problems in the present study.
