title: Directions for nursing theory development in the 21st century.
abstract: The development of the discipline of nursing has gone through four stages: theorizing, developing a syntax, concept development, and philosophical debate. These stages helped in shaping the characteristics of the discipline as a human science, a practice science, a science with social goals to empower nurses to provide effective and quality care, and one in which gender differences and the need for understanding minorities are areas of primary concern. Further theoretical development in the discipline will be driven by population needs and will be characterized by reaching out to meet the integrative and interdisciplinary nature of these needs. Sources of theories of the future are practice, theory and research. It is anticipated that two models will evolve to guide the development of phenomenon-driven theories in the future and that third generation theorists will utilize these models.
