Regarding its strengths, this study is the first genetically informative design to consider the specific relationships between dimensions of ADHD (i.e., hyperactive/impulsivity and inattention), conduct problems and alcohol use problems in adolescence. Also, families were recruited from the community rather than through a clinically referred proband, thus the results are likely to generalize to the population; although this also likely resulted in lower symptom endorsement and possibly less power to detect associations.
