individual Background: This study describes the development and validation of an individual-level well-being assessment and scoring method (IWBS) adapted from the population-based Gallup-Healthways Well-being Index across six domains (physical health, emotional health, healthy behaviors, work environment, basic access and overall life-evaluation).
Methods: Exploratory analyses were conducted on half the sample (n = 2036) using principal component analyses (PCA) with varimax rotation and confirmatory factor analysis was conducted on the second half of the sample (n = 2100) using structural equation modeling to validate the measurement model found by the PCA.
Results: Optimal results in the exploratory sample were achieved for a seven-factor solution, accounting for 52.0% of the variance. All domains displayed adequate reliability, ranging from .42 to .79.
Conclusions: The IWBS met each of the criteria that were established for measurement development. Findings indicated that there was initial support for using the IWBS to assess well-being at the individual level. The IWBS has acceptable psychometrics of reliability, internal and external validity.
