Influence of Perfectionist Tendencies and Subjective Perceptions of Sleep on Subjective Sleep Evaluation and Physiological Sleep Status

Abstract

This study examined the effects of perfectionist tendencies and non-functional beliefs regarding sleep on subjective sleep ratings and physiological sleep status. The participants included 130 patients (86 men and 44 women) who were suspected to suffer from sleep disorders and underwent polysomnography (PSG). The participants were surveyed using the new perfectionism scale, non-functional beliefs and attitudes toward sleep questionnaire, and Athens insomnia scale. The responses were analyzed along with the PSG results. The results demonstrated that perfectionist tendencies and non-functional beliefs regarding sleep influenced subjective sleep evaluation and physiological sleep status, respectively. These findings suggest that psychological approaches can help improve subjective sleep evaluation and physiological sleep status. Furthermore, mitigating perfectionist tendencies and non-functional beliefs regarding sleep may require support.
