The 5-Factor Wel, the latest version of the Wellness Evaluation of Lifestyle (WEL), was examined using a completely new 3.993-person database. Through exploratory and confirmatory factor analysis with 2 discrete subsets of these data, a new 4-factor solution was identified that provided the best fit for the data and accounted for 30% of the variance. In this article, the WoW model and the development and validation of the WEL and 5F-Wel inventories are described. The empirically based Indivisible Self Wellness (IS-WEL) model, the basis of the 5F-Wel, is presented, followed by the results from a comprehensive set of analyses of the 5F-Wel database. These analyses led to a fundamental reexamination of the constructs underlying the 5F-Wel and differing suggestions about the way in which we measure and profile wellness. A new, more parsimonious yet also holistic structure for examining and assessing wellness is presented, and implications for research and counseling are considered.
