Abstract:
Objective:
To determine the sensitivity, specificity and internal consistency of the Malay version GHQ-12 among medical student population. This study determined the appropriate GHQ-12 score to detect distressed medical students.
Methods:
The Malay version of GHQ-12 was derived based on two sources which were the original version GHQ-12 and the validated Malay version 30-items GHQ. The GHQ-12 and the Malay version Beck Depression Inventory-II (BDI-II) were administered to a total of 141 medical students. Distress diagnoses were made based on the Malay version BDI-II. ROC curve analysis was applied to determine the sensitivity and specificity of the GHQ-12 by testing against the BDI-II. Reliability analysis (Cronbach’s alpha and item total correlation) was applied to test internal consistency of the GHQ-12. The analysis was done using SPSS version 12.
Results:
The GHQ-12 sensitivity and specificity at cut-off point of 3/4 was 81.3% and 75.3% respectively with positive predictive value (PPV) of 62.9% as well as area under ROC curve more than 0.7. The Cronbach’s alpha value of the GHQ-12 was 0.85.
Conclusion:
This study showed the Malay version GHQ-12 is a valid and reliable screening tool in detecting distressed medical students. The GHQ-12 score equal to or more than 4 was considered as significant distress. ASEAN Journal of Psychiatry, Vol.11 (1): Jan - June 2009: XX XX.
