Covariates:
Step 1: Sociodemographic factors (age, gender, race/ancestry, marital status, education status, religion, log-transformed income)
Step 2: Sociodemographic factors, medical factors (all other self-reported pain conditions [i.e., arthritis, back/neck pain, headaches, ‘other’ pain], number of non-pain chronic conditions [range=0–11]; for “any pain” column, adjustment for medical conditions includes only number of non-pain chronic conditions)
Step 3: Sociodemographic and medical factors, lifetime mood or anxiety disorder, lifetime alcohol or drug abuse/dependence, K10 score
Step 4: Sociodemographic and medical factors, lifetime mood or anxiety disorder, lifetime alcohol or drug abuse/dependence, K10 score, personality screen
