OBJECTIVE: To validate the Self-Reporting Questionnaire (SRQ-20) and the Edinburgh Postnatal Depression Scale (EPDS) against the Clinical Interview Schedule-Revised (CIS-R). DESIGN: Two-phase design. SUBJECTS AND METHODS: 664 mothers were approached, 601 of them completed the EPDS and SRQ questionnaires. The CIS-R was administered to confirm the diagnosis for depression. The diagnostic accuracy was compared using the receiver operating characteristic analysis. RESULTS: At the threshold of 11, the SRQ had better sensitivity, negative predictive values and positive predictive values compared with the EPDS optimal threshold of 14. CONCLUSION: Both measures (EPDS and SRQ) have adequate validity to screen for depression in mothers in Pakistan. However, the SRQ performed better, with participants finding it easy to understand. The scales can be of great value to detect maternal depression in primary care and pediatric settings in low-income countries.
