This chapter gives a state-of-the–art overview of theory and research on the Job Demands- Resources (JD-R) model. Since its introduction in 2001, the JD-R model has been cited over 9,000 times and is arguably today’s most popular conceptual model in occupational health psychology. The chapter describes the development of the JD-R model, which originally only focused on burnout and later also included work engagement, and discusses extensions of the model, for instance with personal resources. Abundant empirical evidence for the JD-R is reviewed and its practical application is discussed. The chapter concludes with some critical comments and directions for further research (read more).
