The basis of Leininger's Sunrise Model of Transcultural Nursing Care lies in its holistic and comprehensive approach to understanding cultural influences on health, illness, and caring practices. This model emphasizes the interconnectedness of various cultural dimensions, such as social structure factors, technological factors, religious and philosophical factors, kinship and social ties, cultural values, and environmental context. By considering these dimensions, nurses can provide culturally congruent care that is tailored to the unique needs and preferences of each patient.
