This study describes a qualitative inquiry-informing program development in a maternal and child home visiting program. Low-income women's perceptions of the meaning and experiences of depression were ascertained through focus groups and interviews. Simultaneously, the study examines staff member perceptions and roles related to depression. Specific findings from clients and staff reveal culturally situated beliefs about depression and stressful life events; comparing and contrasting these beliefs offers a novel perspective on identification and intervention for maternal depression. This study offers a foundation for a translational research agenda that will be used for program and policy development to enhance mental health services situated within maternal and child health home visiting programs.
