Objective : 1) To assess work-related quality of life (WRQOL) among medical residents at a university hospital in northeast
Thailand. 2) To determine the strength of the association between personal and working condition components and WRQOL
among medical residents.
Material and Method: A descriptive study was used to describe the WRQOL among medical residents. The study population
comprised of all 375 residents affiliated with the university hospital. The Thai version of a self-administered work-related
quality of life scale-2 was used for data collection.
Results : Testing the reliability revealed a Cronbach’s alpha of 0.908. Questionnaires were completed by 259 of 375 (68.3%).
The study found that the mean rating by residents for overall WRQOL was 113.8 out of 170 (SD 14.8). Most rated WRQOL
as moderate (76.6%). The seven sub-factors were rated as moderate to high for employee engagement and control at work,
moderate for home/work interface, general well-being and working conditions, high-moderate for job career satisfaction,
and low-moderate for stress at work. Relationships between the personal and working condition components and WRQOL
were analyzed using binary logistic regression. Residents in minor specialties had a higher WRQOL than those in major
specialties (OR 2.522, 95% CI: 1.37, 4.63). Residents who had less than eight duty shifts/week had a higher WRQOL than
those with more than eight duty shifts/week (OR 2.263, 95% CI: 1.16, 4.41). Similarly, residents working with less than
80 hours/week had a higher WRQOL than those working more than 80 hours/week (OR 2.344, 95% CI: 1.17, 4.72).
A subgroup analyzes of those working in minor specialties showed the trend that working less than eight shifts/month and
working less than 80 hours/week had the potential association with good quality of work-life (QWL). This phenomenon is
presented in the subgroup analyses of those working in major specialties. Therefore, working hours and number of shifts
might have played important role in contributing good QWL.
Conclusion : To increase QWL, the residents and institutions should be better managed to have the appropriate number of
working hours and to increase work-life balance, working condition, general well-being, and job-career satisfaction. On
the other hand, stress at work must be reduced.
