Background/Aims: Bedtime procrastination (BP) is an unhealthy sleep behavior, but its relationship with Type D (distress) personality has never been examined. This study aimed to investigate the relationship between Type D Personality, BP, and Sleep Quality in university students. Methods: In this cross-sectional study, we applied the sociodemographic sleep data form, Type D personality scale (DS-14), Bedtime Procrastination Scale (BPS), Pittsburgh Sleep Quality Index (PSQI) (subjective sleep quality and daytime dysfunction subscales), Insomnia Severity Index (ISI), and Epworth Sleepiness Scale (ESS). All participants were divided into two groups: Type D personality and non- Type D personality. Sleep variables and scales were compared between these two groups. Additionally, correlation analysis was performed between the scales and the subdimensions of Type D personality. Results: We completed our study with 209 university students (66%, n = 138 female and 34%, n=71 male). The mean age was 22.17 ± 4.33, and 51.2% of all participants had Type D personality. Sleep quality was poor, and insomnia was more severe in participants with Type D personality. Participants with Type D personality had more delayed bedtime. Negative affectivity was associated with poor sleep quality, more severe insomnia, and BP, but social inhibition was not associated with BP. Conclusion: Clinicians should consider the negative affectivity sub-dimension of Type D personality contributing to BP behavior among university students when planning interventions to reduce BP behavior.
