The relationships between social network centrality, social construction of knowledge, and nurse practitioner competency among adult gerontology acute care nurse practitioner students participating in asynchronous online discussions were explored. Social network centralities (betweenness, in-degree, out-degree, closeness, and eigenvector) were determined through social network analysis. Social construction of knowledge was assessed by the Interaction Analysis Model (IAM). Nurse practitioner competency was evaluated using the Novice to Expert model. A retrospective exploration of an online discussion board from the College of Nursing at the University of New Mexico was conducted. The centralities of betweenness, closeness, and eigenvector demonstrated a significant relationship with the dependent variable of nurse practitioner competency. Social construction of knowledge did not demonstrate a significant relationship with nurse practitioner competency. The centralities of betweenness, in-degree, out-degree, closeness, and eigenvector demonstrated a significant relationship with social construction of knowledge.Keywords: social network centrality, social construction of knowledge, competency, nurse practitioner, adult gerontology acute care nurse practitioner, asynchronous online discussion, interaction analysis, social network analysis.
