Note. Estimates show the unstandardized relationship between each predictor and the criterion. Bolded text indicates significance at *p < .05. SE=Standard error of estimate/coefficient. PSQI=Pittsburgh Sleep Quality Index. PSS=Perceived Stress Scale. GSI=Global Severity Index of the Symptom Checklist 90. SF-36-GH=General Health Scale of the Short Form Health Survey. NA=Native American. ALEs= Adverse Life Events. CPM=Conditioned Pain Modulation. Sex was coded −1=male and 1=female. Race was coded 0=non-Hispanic white and 1=Native American. AR1=first-order autoregressive structure.
