Best-fitting multivariate model in women. AD-FS = alcohol dependence factor score; BE = binge eating; CB = compensatory behaviors; A = additive genetic effects; E = nonshared environmental effects. This model only includes same-sex female twin pairs, as CB were not asked in men. Dotted arrows represent path coefficients/correlations that could be dropped from the model, whereas solid arrows represent path coefficients/correlations that could not be dropped from the model; 95% confidence intervals are presented in brackets.
