Born in Brussels screening tool: the development of a screening tool measuring antenatal psychosocial vulnerability.

Background: Antenatal psychosocial vulnerability is a main concern in today's perinatal health care setting. Undetected psychosocially vulnerable pregnant women and their unborn child are at risk for unfavourable health outcomes such as poor birth outcomes or mental state. In order to detect potential risks and prevent worse outcomes, timely and accurate detection of antenatal psychosocial vulnerability is necessary.
