The Oxford Pregnancy Study - Study Procedures
Overall, this study involves completing a short screening questionnaire, an antenatal assessment during pregnancy, and an assessment at home approximately 2 months after giving birth. Please see below for a more detailed description of what each session involves.
Part 1 - Screening.
In order to check that potential participants are eligible for the study, they are firstly asked to complete a short screening questionnaire. More details of the inclusion criteria and exclusion criteria can be found here.
Part 2 - Antenatal assessment.
If participants are eligible for the study, they are invited to the Department of Psychiatry at the Warneford Hosptial for the antenatal assessment, or participants are visited at home by a member of the research team if they would prefer. The antenatal assessment takes place during the afternoon between the hours of 2pm and 7pm, and lasts for about an hour and a half in total. This part of the study involves signing a consent form, completing some questionnaires, watching a short video and providing some saliva samples. We also ask participants to collect some further saliva samples at home over 2 days and send them back in the post. The antenatal assesment can take place anytime during the second or third trimester.
Part 3 - Postnatal assessment.
About 2 months after the participants has given birth, they are visited at home by one of the
researchers. Participants are asked to complete another questionnaire and provide some saliva samples from their baby before and after their immunisations.
