Abstract
An early diagnosis to improve the outcome of depression demands a briefer and more reliable measure than any other diagnosis. The Patient Health Questionnaire (PHQ) is reliable measure made in 1999. In this study, we tried to verify the reliabilty and validity of two types of PHQ-2, and to compare these two types.
MethodsZZFrom July of 2011 to September of 2012, a total of 74 outpatients and inpatients in the Department of Psychiatry, Keimyung University Dongsan Medical Center performed the depression scales. As a normal control group, 58 individuals working in the hospital performed the PHQ-2 and PHQ-9.
Results
The internal consistency and test-retest reliabilty were favorable. Two types of the PHQ-2 were statistically significant in correlation between item and total scores. In comparison of mean scores of the PHQ-2 between two groups, the differences between groups were statistically significant. Correaltion of the total scores of other depression scales with those of the PHQ-2 was statistically significant both in scales. Examined according to the severity of depression by other scales, the total mean scores of the PHQ-2 tended to increase according to the severity of depression. The optimal cut-off score was 3 in Scaled PHQ-2 (Sensitivity : 91.9%, Specificity : 100%).
Conclusion
The assessed reliabilty and validity of the PHQ-2 made it an attractive measure for depression screening over other scales. Scaled PHQ-2 was more reliable and valid than Yes or No PHQ-2. Therefore, the PHQ-2 is a briefer and more useful measure for screening depression.
