Response rates were 66.7% (1014/1520) in 2010, 73.1% (1604/2195) in 2016 and 72.5% (1511/2084) in 2019.Main outcome measure Validated 9-item short form of the ‘Effort–Reward Imbalance’ questionnaire. A risky level of work stress was defined as an effort/reward ratio above 1.0.Analyses Linear mixed models with estimated marginal means of job positions controlled for gender and age. Proportions with 95% CIs.Results From 2010 to 2016 and further to 2019, GPs reported a significant increase in levels on the effort scale (ES: 2.96, 3.25, 3.51) and significant decrease in levels on the reward scale (RS: 4.27, 4.05, 3.67). No significant changes were reported by hospital doctors (ES: 3.13, 3.10, 3.14; RS: 4.09, 3.98, 4.04), private practice specialists (ES: 2.58, 2.61, 2.59; RS: 4.32, 4.32, 4.30) and doctors in academia (ES: 2.63, 2.51, 2.52; RS: 4.09, 4.11, 4.14). The proportion of doctors with risky levels of work stress increased significantly for GPs (10.3%, 27.7%, 40.1%), but did not significantly change for hospital doctors (23.0%, 27.3%, 26.9%), private practice specialists (8.2%, 12.7%, 9.4%) and doctors in academia (11.9%, 19.0%, 16.4%).Conclusion During a 9-year period, the proportion of risky levels of work stress increased significantly for GPs but did not significantly change for other job positions. This may be partly due to changes in expectations of younger GPs and several healthcare reforms and regulations. ER -
