Table 1 shows the descriptive information with respect to demographics, closeness with mother and father, parental AUD, SUD, education, income, and offspring P3 amplitude, FT power, binge drinking, and impulsiveness. We first examined the variability of closeness with mother and father by offspring sex. Briefly, male offspring compared to female offspring reported greater closeness with mother (t[1254] = 3.06, p < 0.001; d = 0.17) and father (t[1251] = 1.62, p = 0.05; d = 0.09). Male offspring also reported more binge drinking (t[1251] = 10.31, p < 0.001; d = 0.58). However, female offspring compared to male offspring presented significantly larger P3 amplitudes (t[1044] = 3.50, p < 0.001; d = 0.22) and higher FT power (t[1149] = 5.09, p < 0.001; d = 0.30). Next, as shown in Table 2, bivariate correlations showed that closeness with father was positively correlated with closeness with mother (r = 0.37, p < 0.001). Similarly, offspring P3 amplitude was also positively correlated with offspring FT power (r = 0.26, p < 0.001). Both offspring P3 amplitude and FT power were positively correlated
