The Role of Sleep Quality, Morningness-Eveningness Personality and Sensory Processing Sensitivity in Predicting Nurses' Job Performance of Nurses

Introduction: Nurses are one of the main pillars of health organizations that spend a significant part of their lives in close contact with patients and their job performance has a major impact on patient satisfaction and health. Aim: The purpose of this study was to investigate the role of sleep quality, morningness-eveningness personality and sensory processing sensitivity in predicting nurses' job performance. Methods: The study method was cross-sectional as descriptive-correlational study. The statistical population of the study consisted of all nurses working in public hospitals in Kermanshah, in 2019, among whom 120 were selected through available sampling. Data were collected using four questionnaires: Pittsburgh sleep quality questionnaire, Brown and Dunn sensory profile, Paterson job performance and Horne and Ostberg morningness- eveningness questionnaires. Data were analyzed using Pearson correlation and simultaneous multiple regression tests by SPSS software, version 24. Results: The results showed that nurses' job performance was positively correlated with sensory sensitivity variables and morningness- eveningness personality and negatively associated with low registration and sleep quality (P<0.01). But job performance has no significant relationship with sensory-seeking and sensory avoidance (P>0.05). The results of multiple regression also showed that 61% of the total job performance variance is explained by sensory processing sensitivity, morningness- eveningness personality and sleep quality (P<0.001). Conclusions: According to the results of the study, the variables of sleep quality, morningness- eveningness personality, sensory sensitivity and low registration could significantly predict job performance. Basing the results of this study, selecting work shifts of nurses based on circadian preference, offering necessary training to improve sleep quality and psychotherapies focused on changing sensory processing aimed to increase sensory sensitivity and registration ware suggested to improve job performance of nurses.
