title: Subjective sleep quality exclusively mediates the relationship between morningness-eveningness preference and self-perceived stress response.
abstract: Eveningness preference has been associated with lower sleep quality and higher stress response compared with morningness preference. In the current study, female morning (n = 27) and evening (n = 28) types completed the Pittsburgh Sleep Quality Index (PSQI) and were additionally challenged with an arithmetic stress-induction task. Evening types reported lower subjective sleep quality and longer sleep latency than morning types. Furthermore, evening types reported higher self-perceived stress after the task than morning types. Subjective sleep quality fully mediated the relationship between morningness-eveningness preference and stress response. Poor sleep quality may, therefore, contribute to the elevated health risk in evening types.
