Purpose: Medical students experience various stresses that arise in a special environment. However, there is no specific stress scale for medical students with regard to their environment in Korea. Therefore, in this study, we developed and confirmed the validity of a stress scale for medical students in Korea.
Methods: A draft version of the scale was developed on the basis of open-ended questionnaires from 97 medical students. The validity of the content of this scale was evaluated by three medical educationists. The scale was administered to 435 third and fourth grade medical students as the main survey. For our data, we performed an exploratory factor analysis and confirmatory factor analysis. We used Cronbach α index to determine internal consistency.
Results: Six factors with 40 items were extracted through the exploratory factor analysis: academic stress (9 items); clerkship stress (11 items); interpersonal stress (7 items); career stress (8 items); health-related stress (3 items); and financial stress (2 items). These factors showed a statistically significant correlation. The confirmatory factor analysis demonstrated a favorable RMSEA (0.053) and reasonable fit (CFI=0.847, TLI=0.833). Cronbach α values of the six factors ranged from 0.63 to 0.85.
Conclusion: The medical student stress scale had a good model fit. It is a valid and reliable instrument in identifying stress in medical students and can be used in future studies. Also, the scale is expected to provide individual stress profiles for students to help them manage stress more effectively.
