Overall, individuals in any class with increased internalizing symptoms (PH, LH, MCI, and HL) were less likely to have engaged in at least one of the four alcohol-related outcomes. However, evidence for this association was inconsistent across class and outcome: individuals in LH and MCI were less likely to have binged relative to SL, while those in HL were less likely to have drank alcohol (with or without parental permission) in the last 6 months. With the exception of the LH class, all classes with elevated internalizing symptoms consumed fewer drinks in the previous 6 months than the SL class. Subsequent analyses indicated that no significant differences existed among elevated internalizing classes and the four alcohol-related outcomes (e.g., members of the PH class were no less likely to have binged than members of the MCI class; data available upon request).
