Ethics approval and consent to participate
: Ethics approval for this province-wide study was granted by the University of British Columbia Behavioural Research Ethics Board (#H11–03266), the Vancouver Island Health Authority (#H2012–54), Vancouver Coastal Health Authority (#V11–03266) and the Fraser Health Authority (#2013–055). Once they expressed interest in the study, participants were contacted by email by a research team member and sent the first questionnaire. Initial written informed consent for the prenatal assessment (questionnaire and interview at 33 weeks) was obtained from participants via online and/or mailed forms at 33 weeks in pregnancy. Oral consent was again given by participants at the time of the first interview (33-weeks in pregnancy). Written informed consent for the post-partum assessments (both questionnaires and interviews at 7 weeks and 4 months) was obtained using a second consent form at 7 weeks postpartum. Oral consent was again given by participants at the 7-weeks and 4-months interviews. The consent forms conveyed all the necessary information (e.g. project description, purpose, risk and benefits, confidentiality and anonymity, ways to secure the participants’ data) so that the participants were able to make an informed decision about their participation in the study. All participants gave informed consent for the assessment(s) they completed.
