Residual Covariance Cocaine Estimates (SE)* Methamphetamine Estimates (SE)*
Item 3 with item 9 0.46(0.14) 0.33(0.10)
Item 1 with item 2 0.36(0.10) 0.46(0.10)
Item 4 with item 7** 0.30(0.09) -
Item 8 with item 10** 0.39(0.12) -

Note. Factor loadings and intercepts are provided for items 4 and 7 after reverse scoring. “Means testing” refers to t tests conducted for each individual item and the composite. “STCQ Composite” was computed using the CCQ-Brief scoring method of averaging the responses for all 10 items after reverse scoring items 4 and 7. [Stimulants] = cocaine, methamphetamine, or other stimulants; FL=factor loading; i=item.

*

All factor loadings, intercepts, and residual covariances were significant at the p<0.01 level.
