Final Models Predicting Physical Functioning (PCS-12), Mental Functioning (MCS-12), Disability (SDI), and Quality of Life (QOL) (N = 1,801)

	PCS-12 ↑Scores Indicate Better Physical Functioning		MCS-12 ↑Scores Indicate Better Mental Health Functioning		SDI ↑Scores Indicate More Disability		QOL ↑Scores Indicate Better Quality of Life

Coeff = coefficient; CL = confidence limits; PTSD = posttraumatic stress disorder.
* Indicates standardized regression coefficients with P ≤.001.
† Indicates standardized regression coefficients with P <.05 .
‡ Indicates joint test for categorical variables with more than 2 levels, collapsed across levels for presentation in table.
