An historical overview of Leininger's Theory of Culture Care Diversity and Universality also known as the Culture Care Theory (CCT) and evolution of the Sunrise Enabler are presented along with descriptions of the theory purpose, goal, tenets, basic assumptions, major core constructs, and orientational definitions. Recent articles, books, and book chapters provide relevant exemplars to enhance scholarly understanding and application of theory constructs. Proposed future directions encompass using the CCT to guide research of discovery and translational research projects for evidenced-based nursing practice; develop nursing courses and curricula to prepare culturally competent nurses; guide future culturally competent administrative and leadership policies and procedures; inform public policy related to cultural diversity and underserved populations; promote grant writing initiatives to enhance cultural diversity in hiring nursing staff, supervisors, and faculty; and promote admission of nursing students from underserved and/or diverse backgrounds.
