This is a prospective study of the role of genetic and social factors, and their covariation and interaction, in the development and persistence of patterns of alcohol use and abuse, and associated behavioral, health and social problems. 7-year prospective follow-up data are currently being obtained by mailed questionnaire ('1988 survey'), on a clinically unselected sample of 2,800 adult pairs of monozygotic and dizygotic twins from the Australian twin register. Detailed information about drinking style, personality, general morbidity, educational and occupational achievement and family structure are available on these twins from an earlier 1981 survey. We are seeking funding for (i} a more detailed follow-up, by face-to-face to interview, of an enriched sample of pairs where at least one twin is a probable alcohol abuser (N=400 pairs) and a random sample of pairs (N=400 pairs); (ii) a survey by mailed questionnaire (identical to the 1988 questionnaire) of a new cohort of 1,300 pairs of twins aged 18-25 from the Australian register; (iii) a similar mailed survey of 10,000 of the parents, spouses, siblings and parents-in-law of both 1981 and new samples of twins. Structural equation models will be fitted to these data, to resolve the contributions to persistence and change in patterns of alcohol use and abuse of (a) genetic differences; (b) social interaction between family members (including the effects of parents on their children; children on their parents; siblings on each other; spouses on one another; extra-familial environmental influences shared by twins or siblings); (c) changes in the individual's social environment (leaving home; marriage/cohabitation; separation/ divorce/bereavement); (d) self-selection into adverse environments, including genotype-environment correlation, assortative mating and assortative friendship; (e) the interaction of genetic and social factors with sex, age-cohort or salient features of the individual's social environment (e.g. presence or absence of social support). Hypotheses about the etiologic heterogeneity of alcohol abuse will be tested, particularly regarding the differential associations of type I and type II abuse with Harm Avoidance, Reward Dependence and Novelty Seeking personality dimensions.

这是一项前瞻性研究， 因素及其协变和相互作用 以及酗酒和滥用模式的持续存在， 相关的行为健康和社会问题 7年 目前正在通过邮寄方式获得前瞻性随访数据 问卷调查（1988年调查），临床样本 2,800对成年的同卵双胞胎和异卵双胞胎， 澳大利亚双胞胎注册。 关于饮酒的详细信息 风格、个性、一般发病率、教育和职业 这些双胞胎的成就和家庭结构， 早在1981年的调查。 我们正在寻求资金（i）更多 详细的后续行动，通过面对面的采访，丰富的 至少有一个双胞胎是可能的酒精对样本 滥用者（N=400对）和随机样本对（N=400对）; (ii)通过邮寄问卷进行调查（与1988年 一项新的研究调查了1,300对18-25岁的双胞胎 （三）申请人的姓名或者名称; 双方的父母、配偶、兄弟姐妹和公婆各10，000人 1981年和新的双胞胎样本。 结构方程模型将 拟合这些数据，以解决对持久性的贡献 和改变酒精使用和滥用的模式（a）遗传 差异;（B）家庭成员之间的社交互动 （包括父母对子女的影响;子女对 他们的父母，他们的兄弟姐妹，他们的配偶。 双胞胎共享的家庭外环境影响，或 （c）个人社会环境的变化 （离家;结婚/同居;分居/分居） 离婚/丧亲之痛）;（d）自我选择进入不利环境， 包括基因型与环境的相关性、选择性交配和 （e）遗传和社会的相互作用 性别、年龄组群或显著特征的因素 个人的社会环境（例如，存在或不存在社会 支持）。 关于酒精病因异质性的假设 将对滥用情况进行测试，特别是关于 I型和II型滥用与避免伤害的关联， 奖励依赖与新奇寻求人格维度。
