Abstract

Four hundred and twenty-two employees completed daily diaries measuring positive affect, negative affect, work hours, and health behaviors (snacking, smoking, exercise, alcohol, caffeine consumption) on work days over a 4-week period. In addition, measures of job demands, job control, and social support (iso-strain variables) were completed on 1 occasion. Multilevel random coefficient modeling was used to examine relationships between the job characteristics, daily work variables, and self-reported health behaviors. Results indicated a more important role for within-person daily fluctuations than for between-persons variations in predicting health behaviors. Whereas negative affect was negatively related to health behavior for both men and women, work hours had negative impacts for women only. Iso-strain variables showed few main effects and a modest number of interactions with daily variables (mainly for men). Findings point to the limited impact of stable features of work design compared to the effects of daily work stressors on health behaviors.
