This consensus statement is the result of an invited workshop funded by the Society for Reproductive and Infant Psychology on Measuring Psychological Health in the Perinatal Period which was held in Oxford on the 19th March 2013. The details of those who participated in the workshop can be found at the end of the consensus statement. The workshop evolved out of recognition that a major limitation to research and practice in the perinatal period is identifying valid, reliable and clinically relevant measures of psychological health. Work Shop Aims: To explore the definition and measurement of key components of psychological health and related constructs, in maternity care research. To discuss design and reporting standards of measures in the perinatal period to support measurement development and appropriate use.
