Table 5 presents associations, within the TNAD group, between ERP measures and (a) alcohol-use variables, (b) family history density of alcohol problems, and (c) psychiatric symptom counts. There were only two statistically significant correlations: P3a latency was positively associated with internalizing symptom counts (r = .447, p = .004), and P3b amplitude was negatively associated with regular drinking frequency (r = −.330, p = .040).
