Vacation's lingering benefits, but only for those with low stress jobs.

Vacationing provides potential recovery from work stress and is associated with cardiovascular disease morbidity and mortality. This study considered psychological variables that might change as a vacation is approaching (fade-in) or after a vacation ends (fade-out) and how these associations might vary as a function of ongoing work stress. Methods: Sixty workers eligible for paid time off were recruited from the community. Multiple assessments occurred during an 8- to 10-week period spanning the period before and after a vacation. A piecewise random coefficient model compared changes over time (slopes) for pre- and post-vacation periods. Outcomes included affect, aggression, social support, and work stress. Results: Hostile affect, negative affect, stress, and physical aggression all declined significantly during the post-vacation period (relative to no change during the pre-vacation period). In addition, these changes in pre- versus post-vacation periods differed as a function of work stress, with some vacation benefits observed specifically among workers with low work stress. Conclusions: Findings indicate that vacations produced psychological benefits that persist beyond the vacation period. Vacation-associated benefits may serve as mechanisms underlying associations between vacations and slow developing disease. However, work stress appears to spillover and can thereby undermine a vacation's fade-in and fade-out benefits.
