Burnout of intrinsically motivated GPs when exposed to external regulation

Burnout among general practitioners (GPs) is a problem in many countries. Research indicates that burnout is less likely to occur among intrinsically motivated employees. Based on self-determination theory, we investigate 1) whether intrinsically motivated GPs are less burned out than their colleagues, and 2) whether the most intrinsically motivated GPs are more likely to burn out when exposed to an external regulatory accreditation programme. General practices in Denmark were cluster randomized to mandatory accreditation in 2016, 2017 or 2018. We measure GPs’ intrinsic motivation and burnout levels one and two years into the accreditation process. We use a balanced panel of GPs (n = 846) to estimate mixed effects ordered logit models. We find that GPs with high intrinsic motivation are less burned out than their colleagues. However, the most intrinsically motivated GPs are significantly more burned out when exposed to accreditation compared to their colleagues. We conclude that being intrinsically motivated may not shield from burnout when external regulation is imposed.
