The longitudinal impact of a job crafting intervention

This study examined the impact of a job crafting intervention based on job demands-resources (JD-R) theory. We hypothesized that the intervention would influence participants' job crafting behaviours, as well as their job demands, job resources, and personal resources. In addition, we hypothesized a positive impact of the intervention on work engagement and self-rated job performance. The study used a quasi-experimental design with a control group. Teachers (N=75) participated in the job crafting intervention on three occasions with 9weeks in-between the first and second measurement, and 1year in-between the second and third measurement. Results showed that the intervention had a significant impact on participants' job crafting behaviours, both at time 2 and time 3. In addition, the results showed a significant increase of performance feedback, opportunities for professional development, self-efficacy, and job performance 1year after the job crafting intervention. Participants' levels of job demands, resilience, and work engagement did not change. We discuss the implications of these findings for JD-R theory and practice.
