 There is widespread consensus that postnatal depression(PND) is a common and important mental health problem. Recent national recommendations might serve to reduce considerable variations in current clinical practice. This paper presents a review of basic psychometric property of screening test for PND and the need for reliable and valid screening instruments. Published psychometric data(e.g.,reliability,sensitivity,specificity,positive predictive value,negative predictive value,cut-off point,and timing of screening) of each self-report instrument are presented and critiqued. Screening tool like The Edinburgh Postnatal Depression Scale(EPDS) is the most extensively studied measure with postpartum women with moderate psychometric soundness.  There have been considerable efforts to develop screening programme that might enhance not just the detection but also the successful treatment of PND. This paper also pointed out that success of a screening programme extends beyond the diagnostic accuracy of a screening tool. It is not clear that screening achieves its ultimate goal,namely improving outcomes and reducing the burden of PND. These factors rely on additional patient and clinician factors such as the acceptability of the screen from women and health care givers. An implication for clinical practice,cost effectiveness of formal identification methods for PND in primary care also was discussed.
