“…Male-limited Type II alcoholism, theoretically characterized by heightened severity (Oreland, von Knotting, von Knorring, & Bohman, 1985;von Knorring, Palm, & Andersson, 1985), early onset, and increased heritability (Cloninger, 1987), is often preceded by childhood conduct disorder (Cloninger et al, 1988;Hasin, Grant, & Endicott, 1988;Schaeffer, Parsons, & Errico, 1988;von Knorring, von Knorring, Smigan, Lindberg, & Edholm, 1987) and childhood hyperactivity (Tarter, McBride, Buonpane, & Schneider, 1977). The notion that some relationship exists between attention deficit disorder/hyperactivity and alcoholism is further buttressed by the findings of Horton (1985) and Wood, Wender, and Reimherr (1983), who estimated that 30% to 40% of alcoholics qualify for the Diagnostic and Statistical Manual (third edition) diagnosis of residual attention deficit disorder. Despite widespread differences in methodology and assumption across studies, there is general, unequivocal agreement on the elements of personality, temperament, and behavior that particularly characterize SOMAs, especially those at highest risk for later alcohol abuse.…”
