Objectives: The 12-item General Health Questionnaire (GHQ-12) has been used extensively in a variety of settings across countries. The objectives of this study were to test the factor structure and internal consistency of the GHQ-12 in the Korean general population and to test relationships among the scales, the Center for Epidemiologic Studies Depression Scale (CES-D) and the EuroQoL-5 Dimension Index (EQ-5D).
Methods: Data were acquired from a sample of 6,510 Koreans, aged 18 to 64 years old, who were randomly selected based on the 2005 census (2,581 men and 3,929 women). Participants completed the GHQ-12, the CES-D, and the EQ-5D. Exploratory factor analysis was performed for extraction of factor structures of the GHQ-12. Cronbach’s alpha coefficient was used for assessment of internal consistency. Finally, correlation analysis was performed for assessment of the relationships among the three instruments.
Results: Results of principal axis factoring with oblique rotation solution showed that the GHQ-12 was a measure of psychological distress with a two-factor structure that jointly accounted for 38% of the variance. The internal consistency of the GHQ-12 was high (Cronbach’s alpha=0.79). Concurrent validity indicated a significant positive correlation with the CES-D (r=0.68, p<0.01) and a significant negative correlation with the EQ-5D(r=-0.36, p<0.01).
Conclusion: Findings of this study demonstrated that the Korean version of the GHQ-12 has a two-factor structure and is a reliable and valid instrument that can be used for measurement of psychological distress in Korean adults.
