DAILY WORK STRESS, MOOD AND INTERPERSONAL JOB-PERFORMANCE - A MEDIATIONAL MODEL

A model suggesting that daily work stress influences daily job perform ance through its influence on mood was developed and tested. Seventy-o ne subjects (physicians, nurses and technologists) from three outpatie nt cancer clinics completed questionnaires measuring objective and sub jective stressors, mood and interpersonal job performance at the end o f each workday. Empirical support for the model was obtained and cross -validated using path analysis. As predicted, lagged effects on next d ay's job performance were much weaker. Job-related variables (namely, job experience, job satisfaction, role ambiguity and informational soc ial support) moderated the stress-mood and stress-performance relation ships.
