%X Early medical residents are expected to have a higher prevalence of burnout due to physical and psychological stressors. However psychological distress associated with burnout has not been adequately investigated in a longitudinal manner. We therefore examined the longitudinal trajectory of depression and its associated factors among early medical residents.
In this cohort study, medical residents (n = 215) who started rotation at the University of Yamanashi Hospital during 2012 to 2018 were recruited and asked to complete the Brief Job Stress Questionnaire (BJSQ), Center for Epidemiologic Studies Depression Scale (CESD), Brief Scale for Coping Profile (BSCP) and Athens Insomnia Scale (AIS) at the time of exit from each clinical department for up to two years over seven years. Factors associated with the CES-D scores were statistically explored, with a cutoff score of 16 to denote depression.
The CES-D was completed by 205 residents. The average CES-D score was 10.3 ± 8.0 and the scores were lower in the 2nd versus 1st year of residency (11.3 ± 6.7 versus 9.2 ± 7.0). Multiple regression analysis of BJSQ/BSCP/AIS on CES-D revealed that insomnia had a significant impact on the CES-D scores. Apart from insomnia, avoidance and suppression and peer support had significant effects. Resilient residents, who showed the maximum CES-D score of under 16 consistently throughout the residency, was better in terms of changing a point of view, active solution and changing mood. Women were more likely to express emotions to others, while they reported more job control in the first year.
Our results have high clinical relevance to challenge psychological burnout among early medical residents, offering some possible clues for prevention such as reduced burden, more flexibility during the first year and strengthening coworker support. Insomnia exerted moderate to strong effects on depression and monitoring of sleep appears indispensable in this specific population.
