This study aimed to examine the structural model of time perception and overthinking in relation to sleep problems among individuals with chronic depression, with a particular focus on the mediating role of brain lateralization. This applied research employed a structural equation modeling (SEM) approach. The statistical population consisted of 160 individuals with chronic depression from Khoy County, selected through purposive sampling. Data were collected using questionnaires on time perception, sleep disturbances, hemispheric dominance, and rumination, and analyzed using SPSS-22 and Smart PLS software. The results indicated that overthinking and distorted time perception were directly associated with sleep problems. Additionally, hemispheric dominance significantly mediated the relationship between time perception and sleep problems, but no significant mediating role was found in the relationship between overthinking and sleep problems. Model fit indices indicated a good fit between the model and the data. The findings highlight the importance of cognitive and neural factors in explaining sleep problems in individuals with chronic depression. These results pave the way for the development of integrated therapeutic interventions focusing on the regulation of hemispheric activity and the management of cognitive factors.management of cognitive factors.
