With a paucity of literature on professional organization membership by nurse practitioners (NPs), the authors base the discussion of the personal benefits associated with membership on literature focusing on clinicians other than NPs and their personal experiences as members of multiple organizations. Membership is described as related to NP socialization, engagement, networking, mentorship, advocacy, policy, leadership development, research dissemination, professional development, and volunteerism. In addition to encouraging active participation in one or more professional organizations, the need for research into factors influencing the degree to which NPs participate in organizations and the associated benefits is identified.
