Having a baby is a major life event, and for some women, it can increase the risk of developing mental health issues. A recent survey in the UK found that one in five women experience mental health problems during pregnancy or after giving birth. Unfortunately, many of these problems go unnoticed without regular check-ups, and only one in ten women receive the support they need. Regular mental health screenings can help detect these problems early, ensuring women receive the right care and support.

The study at UZ Gent aims to improve how depression and anxiety are detected in pregnant and postpartum women by using a perinatal screening protocol. This protocol involves screening women for psychosocial risks around the 16th week of pregnancy, which is done by a midwife. Further screenings take place during the second trimester (around 20 weeks) and again six weeks after birth, using questionnaires to assess for depression and anxiety (Whooley, EPDS, GAD-2, GAD-7).

If the assessment of risk factors or the screening for depression and anxiety is positive, further assessment and treatment are offered at the women's clinic. A positive screening may lead to a recommendation for a diagnostic interview, such as a semi-structured interview (M.I.N.I.), with a psychiatrist, general practitioner, or psychologist to assess for possible depression or anxiety disorders. If needed, appropriate treatment will be provided.

The study will explore how common depression and anxiety are during and after pregnancy, what factors increase the risk, and whether the screening process improves early detection and treatment. The ultimate goal is to help more women get the mental health support they need during this critical time.

Inclusion Criteria:

• Pregnant women aged ≥ 18 years, receiving regular care follow-up in a university hospital

Exclusion Criteria:

• Non-Dutch speakers were excluded. Additionally, no data were collected from women in the vulnerable care pathway, which provides psychosocial support to those facing barriers in employment, income, housing, education, and healthcare. This group includes teenage mothers (under 18), women with intellectual disabilities, new immigrants, refugees, homeless women, and those with severe psychiatric or addiction issues referred by their psychiatrist or GP.

The study population consists of women receiving regular care during pregnancy and postpartum follow-up at the women's clinic of University Hospital Ghent

We have decided not to share the IPD collected throughout the trial due to concerns over participant privacy and data confidentiality. Despite efforts to anonymize the data, there remains a risk that sensitive personal information could be inadvertently disclosed.
