Background: Peripartum adolescents experience significant interpersonal transitions in their lives. Depression and emotional distress are often exacerbated by adolescents’ responses to these interpersonal changes. Improved understanding of pregnancy-related social changes and maladaptive responses to these shifts may inform novel approaches to addressing the mental health needs of adolescents during the perinatal period. The paper aims to understand the sources of psychological distress in peripartum adolescents and map these to Interpersonal Psychotherapy’s (IPT) problem areas as a framework to understand depression. Method: We conducted interviews in two Nairobi primary care clinics with peripartum adolescents ages 16–18 years (n = 23) with experiences of depression, keeping interpersonal psychotherapy framework of problem areas in mind. We explored the nature of their distress, triggers, antecedents of distress associated with an unplanned pregnancy, quality of their relationships with their partner, parents, and other family members, perceived needs, and sources of support. Results: We found that the interpersonal psychotherapy (IPT) framework of interpersonal problems covering grief and loss, role transitions, interpersonal disputes, and social isolation was instrumental in conceptualizing adolescent depression, anxiety, and stress in the perinatal period. Conclusion: Our interviews deepened understanding of peripartum adolescent mental health focusing on four IPT problem areas. The interpersonal framework yields meaningful information about adolescent depression and could help in identifying strategies for addressing their distress.

In this introductory paper to the Global Mental Health volume, the inception and development of the filed in the last 15 years is reviewed, placing an emphasis on a series of pivotal turning points. A critical delivery strategy, task‐shifting is briefly described, as well as the fundamental principles of Interpersonal Psychotherapy (IPT), an evidence‐based psychotherapy being adapted and delivered in low‐resource settings. Nine case studies by the trainees, supervisors, or local providers from India, the United States, Haiti, Israel, Colombia, and Kenya, presented in this volume, illustrate the prevention and treatment processes or in‐depth assessment of “psychological distress” as locally defined and expressed.

After the 2010 Haiti earthquake, Zanmi Lasante, a local health care organization, implemented a collaborative stepped-care model to address depression in community and primary care settings in rural Haiti. Specialized community health workers, the ajans santé, collaborate with local psychologists and primary care doctors to offer home-based evaluation, support, and follow-up. The services include brief interpersonal psychotherapy (IPT) and/or medication to persons who met locally defined criteria for depression. A cross-national (Haiti–United States) expert mental health team has been overseeing the program. The present IPT supervision case of a severely depressed, physically abused, and pregnant young woman illustrates the U.S.-based supervisor's internal struggle to reconcile awareness of and respect for local norms while maintaining a human rights-based framework. It also highlights the critical role of community health workers in addressing the mental health treatment gap in regions plagued by extreme poverty and adversity.

Despite established knowledge that Low and Middle Income Countries (LMICs) bear the majority of the world’s burden of mental disorders, and more than a decade of efficacy research showing that the most common disorders, such as depression and anxiety, can be treated using readily available local personnel in LMICs to apply evidence-based treatments, there remains a massive mental health treatment gap, such that 75 % of those in LMICs never receive care. Here, we discuss the use of a new type of implementation science study design, the effectiveness-implementation hybrids, to speed the translation and scale up of mental health care in LMICs. We use our current study of Interpersonal Psychotherapy (IPT) delivered by local personnel for depression and trauma-related disorders among HIV+ women in Kenya as an example of effectiveness-implementation hybrid design for mental health services research in LMICs.
