Does Work Stress Predict the Occurrence of Cold, Flu and Minor Illness Symptoms in Clinical Psychology Trainees?

Objectives: The present study examined the three/four-day lagged relationship between daily work stress and upper respiratory tract infection (URTI) and other minor illness symptoms. Methods: Twenty-four postgraduate clinical psychology trainees completed work stress, cold/flu symptoms and somatic symptoms checklists daily for four weeks. Results: Increases in work stress were observed two days prior to a cold/flu episode but not three or four days preceding a cold/flu episode. Work stress was unrelated to peaks in somatic symptom reporting. Conclusions: There was some evidence of a lagged relationship between work stress and symptoms, but not of the expected duration, suggesting that the relationship between work stress and URTI symptoms was not mediated by the immune system.
