ABSTRACT
Objective:
Using a diagnostic test research,to explore the reliability and validity of the Patient Health Questionnaire (PHQ-9)on screening of depressive disorders in general hospital,and to determine the cut points for depressions with different severities.Methods:
Three hundred and nineteen help-seekers (n =319)con-sulting the outpatient department of psychiatry in a general hospital were collected continuously.Among them,80 were people without any psychiatric diagnosis,239 were patients with mental disorders.All of subjects were asked to fulfill PHQ-9,and were assessed by psychiatrist with Mini-International Neuropsychiatric Interview (M.I.N.I.) and Hamilton rating scale for depression.M.I.N.I.was gold standard to diagnose depressive disorder,HRSD was used to assess the illness severity.Result:
Factor analysis showed good structure validity of PHQ-9.46 patients were diagnosed depressive disorders.The area under the receiver operator characteristic analysis (ROC)of PHQ-9 was 0.94 (95%CI0.91 -0.97)for depressive disorders.With 15 as the critical value for depression screening,the sen-sitivity was 0.83 and specificity was 0.90,respectively.By the result of HRSD as the standard to rank different lev-els of depression,the cut points of PHQ-9 for mild,moderate,and severe depression was 6,12,and 15.The consis-tency between results of PHQ-9 (with cut points of 6,12,15)and HRSD was moderate (with kappa =0.49).The kappa between results of PHQ-9 (with recommended cut points of 5,10,and 15)and HRSD was 0.46.Cronbach αcoefficient of PHQ-9 was 0.892.Conclusion:
It suggests that PHQ-9 has satisfying reliability and validity,and is applicable for screening depression and assessment of its severity of outpatients in general hospital.The recommen-ded cut points of PHQ-9 are applicable to depressive outpatients in general hospital in China.
