Characteristics of self-selected responders to a health risk appraisal: Generalizability of corporate health assessments

Abstract

Selected characteristics and total medical claims of health risk appraisal (HRA) responders and non-responders were compared in a sample of employees having a three-year employment and claims history. HRA responders were younger and more likely to file medical claims that non-responders. Although mean medical claims were greater for HRA responderds than non-responders, when adjusted for age and sex this difference reflected the proportion of employees reporting claims, not a difference in the claims amount.
