The document discusses Maternal Role Attainment Theory and its application to teen pregnancy. The theory was developed by Dr. Ramona Mercer and outlines four stages of becoming a mother: commitment and preparation during pregnancy, acquaintance and learning at birth, moving towards a new normal after birth, and achieving a maternal identity around 4 months postpartum. Adolescent mothers face additional challenges in attaining the maternal role due to their immaturity and the demands of adolescent development. Applying this theory, healthcare providers should support teen mothers and provide opportunities to voice concerns to aid in their development of a maternal identity.
