Results: Two-week test-retest reliability was high (r=0.84) and internal consistency was good (Cronbach’s alpha=0.882). The BDI-2 showed a good criterion validity with strong correlation with Patient health questionnaire 9 (PHQ-9). Factor structure of the BDI-2 was established using the three-factor structure, which explained 43% of the total variance.
Conclusion: The results of the current study indicate that the BDI-2 is an effective and valid scale for evaluation of depression among Korean university students. The findings suggest that the BDI-2 is a promising assessment tool for use in depression and study of depression via the internet.
