  1. Note. Multinomial Logistic Regression.**p<.010, *p<.050 ORs are adjusted for all other variables in the model. Well = reference group; high = reference category; also included in the analysis: age (covariate), sex (male, female), race (Caucasian, Other). If not otherwise specified, variables were divided into tertiles based on their distribution in this sample (low: 0–33%, medium: 34–66%, high: 67–100% of the sample). Model fit χ2 (df = 74, n = 488) = 229.00, p < .001, Deviance χ2 (df = 898, n = 488) = 765.54, p = .999. Omnibus test: dfs for age: 1; sex and race: df = 2, all other variables: df = 4, Pseudo-R 2 (Nagelkerke) = 0.43
