In Brief:
Various theoretical frameworks have been utilized while examining the concept of relationship power. Additionally, the conceptual definition and operational use is inconsistent throughout literature. The proposed definition of relationship power is the relative, perceived and actual ability to influence a relationship partner. Due to the various adverse outcomes related to relationship power (e.g. intimate partner violence, depression), understanding of this concept is essential. Further, a clear understanding is needed to advance nursing knowledge, leading to future research and theory development.
