The book presents an analysis of seven dimensions of maternal psychosocial development during pregnancy. They serve as the foundation for assessment of maternal prenatal adaptation and for psychoeducational and counseling intervention to enhance maternal adaptation. The seven dimensions of maternal adaptation pertain to motivation for and acceptance of the pregnancy, processes involved in evolving a maternal role prenatally, changes in significant kin relationships (with husband/partner and mother), and preparatory emotional, physical, and adaptive processes for labor and delivery. The approach is a scientific analysis of maternal adaptive and maladaptive responses within each psychosocial dimension with excerpts of maternal responses to illustrate differences in adaptation. The book is proposed to address a void in human psychosocial assessment.
