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

项目总结/摘要 长期目标：这项建议的主要目标是使用寿命的角度来研究遗传和环境因素如何影响，并相互作用影响，有问题的酒精参与，个性和饮酒动机。最终，这个项目的目标是提供进一步的信息，基因和环境如何有助于酒精参与，个性和动机，以及在何种程度上基因和环境解释这些结构之间的关系。 具体目标：这项建议的主要目的是前瞻性地检查测量的基因-环境的相关性和相互作用，有助于人格结构以及饮酒动机有关的问题酒精参与，并进一步确定在何种程度上测量的基因-环境的相关性和相互作用，有助于人格和饮酒动机占这些因素与问题酒精参与的关系。这些分析将在包括基因型数据的两个多波数据集中进行。 重要性：该项目的结果可以为识别、治疗和预防酒精使用障碍的改进方法提供信息，并可以澄清基因-环境相关性和相互作用如何影响酒精相关的个性、动机和行为。

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.
