Psychometric Assessment of the Postpartum Depression Predictors Inventory–Revised

Abstract

Identification of women at risk for postpartum depression requires reliable and valid assessment indices. The purpose of this article is to describe the psychometric properties of the Postpartum Depression Predictors Inventory-Revised (PDPI-R). Psychometric assessment of the PDPI-R was conducted in conjunction with the Centers for Epidemiologic Studies Depressed Mood Scale, and the Edinburgh Postnatal Depression Scale, using data from 139 pregnant women who were followed for 8 months after birth. The prenatal PDPI-R demonstrated concept, concurrent, and predictive validity. The postpartum PDPI-R demonstrated concurrent validity. Factor analysis revealed four underlying factors that did not match the original conceptualization of the instrument. Reliability of the total score resulting from the factor analysis was .83. Initial support for the reliability and validity of the PDPI-R was indicated.
