Zero-order correlations between net overall change scores and the number of binge drinking episodes at the two-year follow up were of similar magnitude, whether using the B-BAES or BAES (r = +.09 for both B-STIM and STIM; p = ns; B-SED: r = −.30, p < .01; SED: r = −.23, p < .05). Trajectory analyses were consistent with these correlational analyses in that lower ratings of sedation predicted future drinking trajectory group when using the B-BAES (B-SED: r = −.27, p < .01) or the BAES (SED: r = −.20, p < .05; also reported in King et al., 2011). Finally, analyses with GEE indicated that greater B-STIM scores as well as lower B-SED scores predicted greater binge drinking over the two-year follow up period (ps < .001), which are consistent with analyses reported using the STIM and SED (see King et al., 2011a). Taken together, these results demonstrate that stimulant and sedative responses to alcohol can predict future drinking, whether assessed with the 14-item BAES or the abbreviated 6-item B-BAES.
