Objective: The purpose of this paper is to highlight the psychological implications of concealed pregnancy for women and their babies. This paper will describe the unmet psychological needs of women who experience a concealed pregnancy and the implications for their infants. Background: Concealed pregnancy has no universal definition and is a public health issue. Concealing a pregnancy can be an emotionally distressing and isolating experience for a woman (Conlon 2006). The psychological implications for women who experience a concealed pregnancy are considerable and often unrecognised. Variations in the duration of concealed pregnancy are observed. Revealing a pregnancy which is concealed is a significant time for a woman and a desire for privacy and confidentiality exist. Women who conceal their pregnancies may opt to have their baby adopted or may choose to mother their infant. There exists psychological implications for women in both circumstances. The impact of concealed pregnancy on maternal-infant attachment is unknown. Concealed pregnancy has been neglected as a topic of research. Methods: The findings discussed are based on a review of the literature on concealed pregnancy. The background to this review is a grounded study of Concealed Pregnancy entitled Keeping it Secret The KISS Study Your Story of Concealed Pregnancy. Results: This paper will discuss the psychological implications of concealed pregnancy for women and their babies. The psychological impact of concealed pregnancy on women include emotional distress, fear, anxiety and behaviours such as avoidance, secrecy, isolation, minimisation have been identified. The unmet psychological needs of women who conceal their pregnancy will be presented. The impact of concealed pregnancy on the infant will also be discussed. Serious case reviews in the UK have highlighted a link between concealed pregnancy and neonaticide. Conclusions: This paper will highlight the psychological implications of concealed pregnancy and the paucity of research in this area. The findings have implications for women, their babies, maternity service providers and policy makers. Recommendations for practice and future research will be presented.
