Abstract
Background and Aims: Medical residents are exposed to reduced quality of life (QoL) and life satisfaction (LS) due to long working hours, frequent shifts, and psychological stress. This study aimed to determine the status of QoL and LS and to investigate their associated factors among residents.
Materials and Methods: This cross-sectional study was conducted in 2018 among 241 medical residents at Mashhad University of Medical Sciences using a census sampling method. QoL was assessed using the Short Form-36 Health Survey (SF-36), and LS using the Satisfaction with Life Scale (SWLS).
Results: The mean age of the residents was 31.8 ± 4.45 years, and 61% were female. Overall, 63% of residents reported satisfactory LS (SWLS > 15). LS was significantly associated with residency year and interest (p = 0.001), with 72% of residents who were interested in their specialty reporting higher LS. QoL scores in most domains were significantly higher among third-year residents compared with first-year residents (p < 0.001). Non-surgical residents achieved significantly higher scores in general health, mental health, vitality, social functioning, and bodily pain than those in surgical specialties. Additionally, interest in specialty was associated with better QoL (p < 0.001). A significant positive correlation was observed between QoL and LS (r = 0.543, p < 0.001).
Conclusion: Residency year, specialty, and interest in specialty were associated with QoL and LS among residents. These findings suggest that educational, welfare, and supportive interventions may contribute to improving these outcomes. However, further studies are required to confirm these associations and explore potential causal relationships.
