Stressors and Stressor Appraisals: the Moderating Effect of Task Efficacy

Employees’ cognitive appraisals play important roles in determining how they perceive and react to challenge and hindrance stressors. This study examined the stress process by studying employees’ cognitive appraisals using time-lagged data collected with a time interval of 4 months. There were three major findings. First, challenge appraisals mediated the relationship of job complexity with work motivation and task persistence. Hindrance appraisals mediated the relationship of role conflict with work motivation and task persistence. Second, task efficacy significantly moderated the relationship between job complexity and challenge appraisal, as well as the relationship between role conflict and hindrance appraisal. Employees high in task efficacy were more likely to report challenge appraisals of job complexity than employees low in task efficacy. Employees low in task efficacy were more likely to report hindrance appraisals of role conflict than employees high in task efficacy. Finally, data supported the moderated mediation model in which task efficacy moderated the indirect effect of job complexity on motivation via challenge appraisal. Our study provided important input to the development of stress management interventions.
