The purpose of this article is to examine the phenomenon of "decisional involvement" using the process of concept analysis as outlined by Walker and Avant in Strategies for Theory Construction in Nursing. Today, nurses practice in a complex healthcare environment that is often structured within the organizational framework of shared governance. This framework advocates nurses having a voice in decisions that are made concerning their work environment and practice. Therefore, it is critical for nurses to understand the process of decisional involvement, its relationship to participation in decision-making, its defining attributes, antecedents, consequences, model cases, and empirical referents.
