The past decade has seen tremendous growth and enrichment in nursing's theoretical work. This third edition has therefore been updated, revised, and expanded to cover the gamut of recent developments in theoretical thinking in nursing. This book presents a systematic framework that can be used to examine elements in the field of nursing and posits important concepts that have emerged in the field. The chapters help to enhance readers' understanding about how conceptualizations and theoretical statements are developed and refined in nursing while simultaneously offering a typology of conceptual domains that can be used to delineate theoretical elements essential to nursing. This third edition retains the previous typology of four domains: the domain of client, the client-nurse domain, the domain of practice, and the environment domain.
