Note. Names of parameters freely estimated across groups in each successive model are listed under the Models column. These parameters are successive in that they include parameters freed in previous steps. E.g., in Model C4, pre-to-post path coefficient means that, in addition to the parameters freed earlier, the path coefficient from pre- to post-drink latent variable was also estimated freely across groups. Significance levels represent whether estimated parameters are significantly different than zero:

^*p≤.05,

^**p≤.01,

^***p≤.001.

Significance levels for the t-tests comparing parameter estimates for the no-alcohol vs. alcohol groups are indicated as:

^ap≤.05;

^bp≤.01.

Desc, = descending limb; var. = variance; Pre-Post path = pre to post-drink (descending limb) path coefficient; Practice-Post path = practice to post-drink (descending limb) path coefficient.
