title: Relationship between hostility and subjective sleep quality.
abstract: While hostility and sleep disturbance are the potential risk factors for health problems and disease, few studies have examined the relationship between the two factors. The present study was performed to investigate the relationship between hostility and sleep problems assessed both subjectively and objectively in a nonclinical sample. Sixty-one healthy subjects were enrolled in this study. Hostility was measured according to the Cook-Medley hostility scale. Subjective sleep quality was evaluated according to the global score of the Pittsburgh Sleep Quality Index. Objective sleep was evaluated using actigraphy. A multiple regression analysis revealed that a higher level of hostility was significantly associated with the global score of the Pittsburgh Sleep Quality Index and that a higher level of depression was not associated with the global score of the Pittsburgh Sleep Quality Index. Objective sleep measures were not found to be associated with hostility. Confirming the robust relationship between poor sleep and hostility would have several important treatment implications for preventing health problems.
