The World Health Organization (WHO) developed the World Health Organization Quality of Life Assessment both full and abbreviated version (WHOQOL-100 and WHOQOL-BREF). Thailand developed WHOQOL-BREF-THAI, which includes four qualities of life domains: physical health, psychological health, social relationships, environment and overall quality of life. The objective of this study was to evaluate quality of life of medical residents who have attended the professional training programs. The results of this study will be fundamental information for the healthy and happy workplace program.

The study was a cross-sectional descriptive study. WHOQOL-BREF-THAI was sent to 264 medical residents in Songklanagarind Hospital. The quality of life score was classified into 3 levels: bad, fair and good.

One hundred and thirty two doctors (50.0%) completed the questionnaires. The scores for the overall quality of life, physical health, psychological health, social relationships and environmental domains in the fair/good levels were 74.6/22.0%, 72.1/27.1%, 68.8/25.6%, 72.8/23.2%, and 70.5/ 22.5%, respectively. Pearson chi-square test showed a significant correlation among the 4 domains. Four questions which showed a lower score were “How satisfied are you with your health?” “How satisfied are you with your sleep?” “How available is the information that you need in your dayto-day life?” “To what extent do you have an opportunity for leisure activities?”.

The results showed that most medical residents had a fair quality of life and there was significant correlation among the 4 domains. Therefore, the 4 domains should be improved at the same time.
