We examined levels of burnout and relationships between burnout, gender, age, years in training, and medical specialty in 158 medical residents working at the University Medical Center Groningen, the Netherlands. Thirteen percent of the residents met the criteria for burnout, with the highest percentage of burnout cases among medical residents in Psychiatry. Significantly more male residents than female residents suffered from severe burnout. Medical residents reported significantly lower mean scores on personal accomplishment than medical specialists and other health care workers; they also reported lower mean scores on emotional exhaustion than medical specialists. Male residents had significantly higher depersonalization scores than female residents. Positive significant relationships were found between personal accomplishment and age and years in training. Obstetrics & Gynecology residents reported significantly more personal accomplishment than residents in Psychiatry, Internal Medicine, Pediatrics, and Anesthesiology. Residents in Psychiatry had significantly lower scores on personal accomplishment than residents in Internal Medicine. Our findings show that burnout is present in a small but significant number of medical residents.
