DeLongis, A., Coyne, J. C., Dakof, G., Folkman, S., & Lazarus, R. S. (1982). Relationship of daily hassles, uplifts, and major life events to health status.

100 45–64 yr olds completed a hassles scale, an uplifts scale, a recent life events schedule, and a health status questionnaire. Analysis showed that hassles—the repeated or chronic strains of everyday life—were more strongly associated with somatic health than were life events. Hassles shared most of the variance in health that could be accounted for by life events, and when the effects of life events were statistically removed, hassles and health remained significantly related. Daily uplifts made little contribution to health that was independent of hassles. The assessment of daily hassles appears to be a useful approach to the study of life stress and could be an important supplement to the life events approach that, alone, is insufficient for full understanding and practical prediction of health outcomes.
