Modern wellness is a concept that has been discussed in the literature since the 1960's. To better understand wellness complexities in a school setting, a concept analysis was conducted using a modified version of Walker and Avant's method incorporating the nursing paradigm in the implications. A literature review was conducted and except for background information, the publication dates were limited to 2017-2022. Key search terms included "wellness," "school wellness," "wellness concept." Additional literature reviews were conducted based on data related to the definitions, attributes, antecedents, and consequences of wellness that were collected from the reviewed studies. Defining attributes of wellness included healthy habits, conscientiousness, and optimum state of health. The antecedents, consequences, and empirical referents of wellness were identified with examples from the literature and case exemplars. Wellness is a dynamic process that has unique implications for school health and school nurses. This concept analysis lays the foundation for future research incorporating nursing domains.
