However, studies demonstrate significant discrepancies between clinical psychiatric diagnoses with those made using structured interviews suggesting that clinicians do not systematically apply the diagnostic criteria. Many uses assume a relatively faithful application of the DSM diagnostic definitions. The clinical use of the Diagnostic and Statistical Manual of Mental Disorders (DSM) is explicitly stated as a goal for both the DSM Fourth Edition and DSM Fifth Edition (DSM-5) revisions. However, the test could yield a considerable amount of false positives that would require specialized evaluation to establish a reliable diagnosis. PHQ-2 show an acceptable test performance in the context of the study. Since this study was done with people attending hospital, which could has implications for the prevalence of depression, affecting the validity indicators of the instrument. Kappa coefficient between PHQ-2 and MINI for depression was. The optimal cut point was ≥2 with the following indicators: sensitivity 0.87 specificity 0.74 Youden index 0.60 PPV 0.47 NPV 0.95 (LR+) 3.24 (LR-) 0.18 (95% CI 0.09-0.37). Spearman's rho coefficients for correlations with PHQ-9 and HADS-D scores were 0.63 and 0.59 (p<0.01). Internal consistency, convergent validity and criterion validity were calculated by analyzing the Receptor Operating Characteristics (ROC) and the area under the curve (AUC).Ĭronbach's alpha and McDonald's omega coefficients were 0.71. PHQ-2 were assessed in 243 patients in general medical consultations using the Mini-International Neuropsychiatric Interview (MINI) as the gold standard. The psychometric properties of PHQ-2 in the Colombian population are unknown. The PHQ-2 is a screening test for major depressive disorder (MDD) derived from PHQ-9, which has shown to be useful in the detection of cases of clinical significance in previous studies.
