Recommended method of case-identification (PHQ-2 ≥ 3) missed an unacceptable number of women at-risk of depression. As a clinical decision-making tool, an alternative, dichotomous method maximized case-identification and is recommended. Further, the literature identified inconsistent reporting of the PHQ-2 and the alternative case-identification method hindering the ability to synthesise data. The future use and reporting of consistent question wording and response format will improve outcome reporting and synthesis. Further research in larger and diverse maternity populations is recommended.
