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)
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)
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)
Current models of sleep regulation postulate both a homeostatic and circadian component and promise an understanding of disturbed and displaced sleep. Estimates of these components have traditionally required relatively cumbersome and costly measures, including sleep electroencephalograms and continuously recorded rectal temperature, but it has recently(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)
Two experiments investigated whether forming an if-then plan or implementation intention could break the link between mood and risky behaviour. In Expt 1, participants planned how to deal with unpleasant moods. Next, as part of an ostensibly unrelated experiment, participants underwent a disguised mood induction before rating their willingness to perform a(More)
A field study investigated the ongoing use and effectiveness of self-regulation strategies for improving mood and the effects of a mood-regulation intervention. Thirty trainee teachers used pocket computers to complete ratings of their mood and their use of mood-regulation strategies every 2 hr during 2 weeks of a school placement. Cognitive distraction was(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)
Experience sampling methodology was used to examine how work demands translate into acute changes in affective response and thence into chronic response. Seven accountants reported their reactions 3 times a day for 4 weeks on pocket computers. Aggregated analysis showed that mood and emotional exhaustion fluctuated in parallel with time pressure over time.(More)
