BACKGROUND Several studies of healthy volunteers have revealed that subjective mood may vary with the duration of prior wakefulness and with the time of day. However, in these studies, the effects of extended wakefulness and circadian phase remained confounded, and the interaction of these 2 processes could not be assessed quantitatively. METHODS In the(More)
The study used a time-sampling method to test aspects of A. Grandey's (2000) emotion regulation model of emotional labor. Eighteen customer service employees from a call center recorded data on pocket computers every 2 hr at work for 2 weeks. Participants completed ratings of emotion regulation, events, expressed and felt emotions, well-being, and(More)
Are the moods and subjective performances of professional sports players associated with the ongoing collective moods of their teammates? Players from 2 professional cricket teams used pocket computers to provide ratings of their moods and performances 3 times a day for 4 days during a competitive match between the teams. Pooled time-series analysis showed(More)
The authors consider how multiple dimensions of affect relate to individual proactivity. They conceptualized proactivity within a goal-regulatory framework that encompasses 4 elements: envisioning, planning, enacting, and reflecting. In a study of call center agents (N = 225), evidence supported the distinctiveness of the 4 elements of proactive goal(More)
Mind-wandering is closely connected with negative mood. Whether negative mood is a cause or consequence of mind-wandering remains an important, unresolved, issue. We sought to clarify the direction of this relationship by measuring mood before and after mind-wandering. We also measured the affective content, time-orientation and relevance of mind-wandering(More)
Controlled interpersonal affect regulation refers to the deliberate regulation of someone else's affect. Building on existing research concerning this everyday process, the authors describe the development of a theoretical classification scheme that distinguishes between the types of strategy used to achieve interpersonal affect regulation. To test the(More)
The authors developed and tested a process model of adaptation to shiftwork, which hypothesizes that various individual and situational variables influence the development of sleep and social and domestic disturbances. Both types of disturbances trigger various types of coping behavior, leading to several proximal outcomes. The end result is the development(More)
Although there are strong popular beliefs about the value of a good night's sleep, there is very little documented evidence of day-to-day relations between sleep and well-being. In this study, covariations between sleep and both prior and subsequent daily states of well-being were studied in a healthy, employed sample. Thirty volunteers used pocket(More)
Although regulations on work hours usually include a minimum weekly rest period, there is little empirical evidence concerning recovery from work. Shift-working nurses (N = 61) used a handheld computer for 28 days to complete self-ratings, cognitive-performance tasks, and a sleep diary. Many measures were worse on rest days that followed a night shift(More)
