To address the association between personality and weight, we take a comprehensive approach both concurrently and longitudinally. We assessed FFM personality traits at the more circumscribed facet level, as well as at the broad domain level. Recent research on facet-level analyses indicated that associations at this level do not necessarily follow their domain-level associations (Sutin, Terracciano, Deiana, Naitza et al., 2010; Sutin, Terracciano, Deiana, Uda et al., 2010). These differences reflect the heterogeneous nature of the five broad domains and speak to the importance of examining more circumscribed traits. In addition to a comprehensive approach to personality traits, we also take a comprehensive approach to adiposity. Most previous research has focused exclusively on BMI (primarily with self-reported weight), but BMI might not be the most relevant measure of adiposity to health outcomes. Therefore, in addition to BMI derived from staff-assessed weight and height, we also tested whether personality shared similar relations with three other adiposity measures: waist circumference, hip circumference, and body fat. We then move beyond concurrent associations to examine the longitudinal relations between personality and BMI in two
