The relationship between interpersonal trauma and substance misuse in pregnancy – a narrative review of the literature

BackgroundThere is a strong body of evidence supporting associations between interpersonal trauma (IPT) and substance use; however, this tends to focus on associations between childhood trauma and substance use in non-pregnant populations. Neonatal and obstetric outcomes are poorer among pregnant women with problematic substance use, yet few studies have explored IPT as a possible mechanism underlying their use of substances.AimTo explore the literature regarding the relationship between IPT and substance misuse among pregnant women.MethodA systematic search of relevant databases was conducted and a narrative review of the literature was undertaken. Titles, abstracts and full articles were screened against inclusion criteria. Data were extracted and quality assessed.FindingsA total of 15 studies were identified that suggested associations between negative life events and substance misuse in pregnant women/new mothers.ConclusionsAlthough a link between IPT and substance misuse is suggested, this review has highlighted a number of important gaps in the literature that warrant further investigation. These include a paucity of UK-based studies, and a lack of research that fully explores possible associations between IPT and substance use in pregnant women. Moreover, research to date has employed quantitative methodology
