Occupational stress: its causes and consequences for job performance.

This paper reports two studies of occupational stress and its relation with antecedent variables and job performance. The first study, in which 104 nurses participated in group discussions and 96 nurses completed a questionnaire, identified 45 stressful events for nurses. In the second study, 171 nurses who completed another questionnaire were also rated by a supervisor and/or a co-worker. Ratings of interpersonal aspects of job performance (such as sensitivity, warmth, consideration, and tolerance) and cognitive/motivational aspects (such as concentration, composure, perseverence, and adaptability) correlated significantly with self-reported perceptions of stressful events, subjective stress, depression, and hostility. Models developed through path analysis suggest that the frequency and subjective intensity of the 45 events identified in Study 1 cause feelings of stress, which lead to depression, which, in turn, causes decrements in interpersonal and cognitive/motivational aspects of job performance.
