RecruitingBehavioural interventionFeasibility and Acceptability of a Novel Cognitive Behavioral Skills Mobile App for Pregnant and Postpartum IndividualsThis study aims to assess the feasibility and acceptability of the Maya Perinatal Cognitive Behavioral Skills App, a novel app for pregnant and postpartum individuals experiencing difficulties with mood, anxiety, or stress. Participants will complete the 12-module app to learn evidence-based strategies previously shown to help manage mood and anxiety. Assessments will include app feedback questionnaires, feedback interviews, a daily symptom tracker, and symptom measures. The study investigators hypothesizes that participants will find content to be helpful in developing skills to manage anxiety and mood difficulties during the perinatal period, and that the app interface, session structure, and pacing will be acceptable and feasible for this population. It is further hypothesized that increased Maya Perinatal Cognitive Behavioral Skills App use, engagement, and satisfaction will be associated with lower self-reported anxiety and mood symptoms.
