  Background
There 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.

Aim
To explore the literature regarding the relationship between IPT and substance misuse among pregnant women.

Method
A 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.

Findings
A total of 15 studies were identified that suggested associations between negative life events and substance misuse in pregnant women/new mothers.

Conclusions
Although 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.
