| Variable | b | SEB | B | R2 | ΔR2 |
|---|---|---|---|---|---|
| Step 1 | 0.93 | 0.93 | |||
| Trauma type | 0.006 | 0.001 | 0.204 | ||
| Income | 0.001 | 0.001 | 0.117 | ||

b = unstandardized regression coefficients; SEB = standard error of b; B = standardized regression coefficients; R2 = coefficient of determination, the proportion of variability in a data set that is accounted for by the statistical model.
PTSD = Posttraumatic stress disorder
