Within an extended challenge–hindrance framework, it is assumed that job demands are subjectively appraised both as challenges (that is, as working conditions that are associated with potential personal gains) and hindrances (as working conditions associated with constrains) at the same time. In accordance with transactional stress theory, the association between demand intensity and work-related attitudes (work satisfaction) and psychological strain (burnout) is expected to be mediated by individual appraisal. Moreover, because curvilinear relationships between demand and challenge and hindrance appraisals are assumed, and appraisal is expected to be moderated by job control and social support, we tested complex nonlinear moderated mediation models for four types of job demands (task difficulty, time pressure, interruptions, and responsibility). Based on cross-sectional data of a heterogeneous sample of employees, we confirmed simultaneous challenge and hindrance appraisals. Challenge components are positively associated and hindrance components are negatively associated with favorable outcomes (higher work satisfaction and lower burnout). Challenge appraisals are found to be more relevant for work satisfaction, while hindrance appraisals are more relevant for burnout. The relationship between demand intensity and challenge appraisal is confirmed as curvilinear, whereas hindrance appraisals are approximately linearly related to demand intensity. The relationship between demand intensity and outcome variables is partly mediated by challenge and hindrance appraisal, and significant interaction effects suggest that the appraisal process is moderated by job control and social support.
