DemandsResourcesmodel

The Demands-Resources model, commonly referred to as the Job Demands-Resources (JD-R) model, is a theoretical framework in occupational health psychology that explains how characteristics of work affect employee well-being and performance. It was developed in the early 2000s by Demerouti, Bakker, Nachreiner, and Schaufeli and has since been refined through ongoing research. The model is designed to be applicable across occupations and sectors, accommodating a wide range of job features.

The core concepts of the model organize work characteristics into two broad categories: demands and resources. Job demands are physical, psychological, social, or organizational aspects of the job that require sustained effort and are associated with certain costs if excessive. Job resources are elements that help achieve work goals, reduce job demands, or stimulate learning, growth, and motivation. Personal resources, such as self-efficacy, resilience, and optimism, can influence how individuals respond to demands and utilize resources.

Two primary processes drive the model’s predictions. The health impairment process suggests that high demands exhaust energy and contribute to burnout and health problems. The motivational process proposes that adequate resources foster engagement, commitment, and higher performance. Resources can buffer the adverse effects of demands, particularly when demands are high, and can amplify positive outcomes when resources are plentiful.

Applications of the JD-R model span research and practice, including predicting burnout, engagement, job satisfaction, turnover intentions, and performance. It informs interventions aimed at redesigning work to reduce demands or boost resources and at developing employees’ personal resources. Limitations include reliance on self-report measures and the need for stronger causal evidence through longitudinal or experimental studies.
