Objective: Abundant research has linked nightly sleep as an antecedent of daily psychosocial experiences; however, less is known about sleep's influence on daily expectations of these experiences. Therefore, this research examined the day-to-day associations of sleep quality, duration, and efficiency with next-day expectations for stress(ors) and positive experiences, as well as whether these expectations were related to end-of-day reports of physical symptoms., Methods: In Study 1, U.S. adults ( n = 354; ages 19 to 74) completed twice-daily diaries for 10 weekdays about sleep, expectations for encountering daily stressors and positive events, and physical symptoms. In Study 2, adults in Canada ( n = 246; ages 25 to 87) wore a sleep watch for 14 consecutive days and completed mobile surveys 5×/day about sleep, stressfulness and pleasantness expectations, and physical symptoms., Results: Multilevel models indicated that self-reported sleep quality and duration, but not efficiency, were associated with lower next-day expectations for stressors (Study 1) and stressfulness (Study 2). Self-reported sleep quality (Study 1) and all sleep indices (Study 2) predicted greater next-day expectations for positive events and pleasantness, respectively. For actigraphy-assessed sleep (Study 2), only longer-than-usual actigraphic sleep duration was associated with lower stressfulness expectations, whereas both sleep duration and efficiency were positively linked with daily pleasantness expectations. Only pleasantness expectations (Study 2)-but not daily stressfulness and event expectations (Study 1)-predicted end-of-day physical symptoms., Conclusion: Findings suggest the importance of sleep on expectations of next-day stress and positive experiences, of which may have implications for daily physical health., (Copyright © 2024 by the American Psychosomatic Society.)

Multiple studies have focused on the role of psychosocial factors as predictors of COVID-19 vaccination willingness and uptake, with less attention paid to whether vaccination itself could influence wellbeing. The current study evaluated this possibility with respect to sense of purpose, the perception one has goals and a direction in life, building on previous evidence this factor may influence vaccination willingness and decision-making. Across seven waves of monthly data from February to August 2021, participants (n = 2169, m age  = 48.0 years) across Canada and the United States reported on their sense of purpose and vaccination status. Using piecewise regression models, results indicated that sense of purpose did not appear to fluctuate in the month prior to, during, or following COVID-19 vaccination. However, across most months of the survey, vaccinated participants did report greater sense of purpose relative to unvaccinated participants. These findings are discussed with respect to whether health behaviors, such as vaccination, should be viewed as behaviors indicative of leading a purposeful life., Competing Interests: Declaration of competing interest The author declares the following financial interests/personal relationships which may be considered as potential competing interests: Nancy Sin reports financial support was provided by Government of Canada Social Sciences and Humanities Research Council.
