Seligman (2011) introduced well-being theory as a multidimensional model to increase and measure well-being. The PERMA model of well-being theory defines well-being in terms of five constructs: Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment. Together, these five constructs are the foundation of individual and community well-being. The end goal of well-being theory is flourishing, which is defined as optimal well-being, where one is in the upper range of all five PERMA elements. The purpose of this study was to test whether all five PERMA elements of well-being could be derived from items in the "2018 Purdue Student Experience at a Research University" (SERU) survey, thus providing support for the multidimensional model in context of undergraduate students at a research-intensive university. Using confirmatory factor analysis, all five PERMA constructs were supported with use of 32 items and demonstrated good model fit statistics. A second order PERMA well-being construct was built and demonstrated adequate model fit with RMSEA = 0.04. In the full PERMA model, all 32 items were significant at p < 0.05. In the full PERMA model, all five constructs were significant at p < 0.001. Accomplishment had the highest factor loading (0.76) and Meaning had the lowest factor loading (0.25). Results from this study provide initial support for use of wellbeing theory in context of undergraduate students.
