Criteria for discontinuing or modifying allocated interventions {11b}
suicidality
Following randomization, peer counsellors will attempt to reach participants via telephone, text, and email (as necessary). Participants who do not respond after 8–10 attempts to establish contact will no longer receive treatment but will remain in the study. If any response is provided to attempted contact, peer counsellors will continue to reach out to schedule remote-counselling sessions, unless the participant expresses a desire to withdraw from the study or they reach the end of pregnancy. Participants will also no longer receive treatment if they do not complete the intervention before the end of pregnancy. If acute suicidality is indicated, either through the study questionnaires or in weekly remote-counselling sessions, the participant will no longer receive treatment and the clinical team will provide a referral to the appropriate care resources using the established referral pathway.
