Genetic and Environmental Influences on Personality, Drinking Motives, and Alcoho

长期目标：本研究的主要目标是从生命周期的角度来研究遗传和环境因素如何影响和相互影响问题性饮酒、个性和饮酒动机。最终，该项目的目标是提供基因和环境如何影响酒精参与、个性和动机的进一步信息，以及基因和环境在多大程度上解释了这些构式之间的关系。

Project Summary/Abstract Long-Term Objectives: The primary goal of this proposal is to use a lifespan perspective to examine how genetic and environmental factors influence, and interact to influence, problematic alcohol involvement, personality, and drinking motives. Ultimately, the goal of this project is to provide further information on how genes and environment contribute to alcohol involvement, personality, and motives, and to what extent genes and environment explain the relations among these constructs. Specific Aims: The primary aims of this proposal are to prospectively examine measured gene-environment correlations and interactions that contribute to personality constructs as well as drinking motives related to problematic alcohol involvement, and to further determine the extent to which measured gene-environment correlations and interactions contributing to personality and drinking motives account for the relation of these factors with problematic alcohol involvement. These analyses will be conducted in two, multiwave datasets that include genotypic data. Significance: The results from this project could provide information towards improved approaches for identifying, treating, and preventing alcohol use disorders and could clarify how gene-environment correlations and interactions influence alcohol relevant personality, motives, and behaviors.
