While the hypothesis that impulsive sensation seeking would mediate a portion of the relationship between parental history of alcohol problems and current alcohol use and current concomitant alcohol-tobacco use was not confirmed, the three other hypotheses appeared supported by these data. As expected, all alcohol use variables and concomitant alcohol-tobacco use were significantly associated with higher ImpSS scores. Also, parental history was associated with current use in a similar fashion, as those with a parental history were more likely to use alcohol more often, binge on alcohol, and use both alcohol and tobacco. Finally, adolescents with a parental history of alcohol problems had significantly higher impulsive sensation seeking scores than those who had no parental history.
