Earlier age of first drink (AFD) of alcohol is associated with higher rates of alcohol abuse and dependence as well as a range of other externalizing problems. This study tested the hypotheses that in young adults earlier AFD is associated with [1] the common variance among externalizing problems (lifetime alcohol, marijuana, other drug, childhood conduct, and adult antisocial behavior problems) rather than being uniquely associated with alcohol problems, and [2] the disinhibited personality traits of social deviance and impulsivity, and that the association between earlier AFD and externalizing problems is partly accounted for by disinhibited personality. The sample (N=502) included 299 young adults with a history of alcohol dependence (AD) and 203 subjects with no history of AD. Analyses showed that [1] earlier AFD was associated with the covariance among the different domains of externalizing problems and was not unique to any one externalizing problem, [2] earlier AFD was associated with social deviance and impulsivity, and [3] social deviance and impulsivity accounted for part of the association between earlier AFD and externalizing problems. The results suggest that earlier AFD is associated with a vulnerability to disinhibitory disorders and is not specifically associated with alcohol problems.
早期饮酒（AFD）与更高的酗酒和依赖率以及一系列其他外化问题有关。本研究检验了以下假设：在年轻人中，早期 AFD 与[1]外化问题（终身酗酒、大麻、其他药物、儿童期品行问题和成年反社会行为问题）的共同方差相关，而不是与酒精问题独特相关，以及[2]社交越轨和冲动的抑制解除人格特质，以及早期 AFD 与外化问题之间的关联部分归因于抑制解除人格。该样本（N=502）包括 299 名有酒精依赖（AD）病史的年轻人和 203 名无 AD 病史的受试者。分析表明，[1]早期 AFD 与不同外化问题领域的协方差相关，而不是与任何一个外化问题独特相关，[2]早期 AFD 与社交越轨和冲动有关，[3]社交越轨和冲动解释了早期 AFD 与外化问题之间关联的一部分。结果表明，早期 AFD 与抑制解除障碍的易感性有关，而不是与酒精问题特异性相关。
