Perinatal Depression
Conditions
Brief summary
Investigators developed Motherly 1.0, a smartphone app designed to treat and promote maternal mental health. A 2-arm parallel-randomized controlled clinical trial (RCT) will be conducted to test the efficacy of Motherly in conjunction with brief cognitive-behavioral therapy. 70 pregnant women between 16-40 years old will be recruited. Since all interventions will be conducted online, participants will be recruited from any Brazilian state or municipality. Participants will be randomly assigned to either receive intervention via app consisting of behavioral activation and psychoeducation to promote changes in sleep, nutrition, and physical activity habits, as well as to engage in prenatal care, breastfeeding, and social support, and to stimulate child development, in addition to brief cognitive-behavioral therapy (CBT) (n=35); or to a comparison group receiving an psychoeducational app (active control) with psychoeducational content about gestation, maternal health and mental health, and child development in addition to brief CBT (n=35). Duration of treatment will be eight weeks, during which participants in both groups will be assessed at the beginning (baseline; T0), weeks 3-4 (midpoint; T1), and week 8 (endpoint; T2) in order to evaluate treatment effects. A follow-up postnatal assessment will also be conducted when the child is three months of age (T3).
Interventions
A mobile app designed to promote life habits that have been shown to improve physical and mental health in pregnant women. The app consists of a package of specific and customized interventions defined by eight different modules: 1) Mental Health; 2) Sleep; 3) Nutrition; 4) Physical activity; 5) Social support; 6) Prenatal support; 7) Postnatal support, and 8) Library of pre and postnatal content. The app relies on extensive psychoeducational content delivered as tutorials, brief messages, and available as a library that can be read at the users' discretion; behavior monitoring using schedules, checklists, and notifications to help participants keep track of their health care visits, and schedule behavior activation activities; and gaming elements such as changes in background appearance to reflect participant's mood assessment and ratings of activities, and graphical and easy-to-use questionnaires for obtaining information (mood, nutrition habits).
Brief Cognitive-Behavioral Therapy (CBT) with a focus on behavioral activation (BA). Participants will be guided by psychotherapists to plan, schedule, and engage in positively reinforcing activities, and will be aided to develop problem-solving strategies for circumventing barriers to completing scheduled activities. Implementation of these techniques will be conducted with the aid of the Motherly 1.0 for participants in the experimental arm; for participants in the control arm, BA will be implemented without the aid of Motherly 1.0. Throughout the four sessions, psychotherapists will monitor participants' adherence, answering questions about the strategies and providing support for solving problems or CBT techniques, such as cognitive restructuring, relaxation techniques, sleep hygiene, stress and anxiety management, among other evidence-based techniques might be used if appropriate to the case.
A simplified version of the Motherly 1.0 app consisting of psychoeducational content about various aspects of pregnancy, maternal physical and mental health, and child development. Active intervention functionalities, such as behavioral activation, activity scheduling, sleep hygiene, among others, are NOT present in this simplified version of the app.

Participant flow
Recruitment details
Participants were recruited via social media advertisements from August to September 2020. After demonstrating interest in the study, potential participants were referred to a website page where they were informed of the study's aims, procedures, assessments, and nature of the interventions. They responded to an online survey assessing eligibility criteria. Eligible participants were invited to a baseline assessment conducted via internet or telephone.
Pre-assignment details
Three hundred and twenty (320) women registered online, but 188 did not meet eligibility criteria and one had a duplicated registration. Thirty-six (36) women were excluded in a brief telephone because they did not meet eligibility criteria or declined to participate in the study. Ninety-five (95) women were scheduled for baseline assessment, but 14 cancelled or missed the appointment. Eighty one (81) participants were enrolled and randomized to intervention (N=37) or active control (N=44).
