PDI-14: Perinatal Depression Inventory

The PDI-14 (Perinatal Depression Inventory) accurately measures depression severity across a wide range of perinatal populations.

Perinatal depression is a mood disorder which can affect any woman during pregnancy and after childbirth. Between 320,000 and 1,000,000 women in the USA suffer from perinatal depression each year [1]. Universal screening rarely occurs, and it’s estimated that more than half of women with perinatal depression go undetected [2].  It’s important to provide timely treatment for this common mental health issue. There has been a great need for a reliable perinatal instrument – not just one that assesses the presence/absence of symptoms, but one that accurately measures the severity of the depression.

The PDI-14 (Perinatal Depression Inventory) is a simple, brief self-report inventory written at a fifth-grade reading level. This assessment was developed with input from pregnant and post-partum women, Ob-Gyns, midwives, psychiatrists and psychologists. The PDI-14 accurately measures severity across a number of populations – pregnant/postpartum, white/non-white and private-clinic/public-clinic populations. PDI-14 scores correlate with the PHQ-9, EPSDS and BDI-II, but the PDI-14 provides a more precise measure of severity using far fewer words.

The PDI-14 is a brief assessment which excels at accurately measuring depression severity across a wide range of severity and perinatal populations. Currently it is available free-of-charge to clinicians. EHR integrations are available upon request.
