A scale based on alcohol-related behaviors and an item on shared friends from the National Merit Twin Study were used in an attempt to confirm the finding of Cleveland et al. (1995, J Genet Psychol 166:153-169) of gene-environment correlation in adolescents' drinking behavior, a correlation based on the differential selection of peers. Results from samples of 490 MZ and 336 same-sex DZ pairs were consistent in direction with the hypothesis, although quantitatively modest. This consistency appeared, however, to depend entirely on the female twins in the sample.
采用了基于酒精相关行为的量表和来自国家优秀双胞胎研究的共同朋友项目，试图证实克利夫兰等人（1995 年，《遗传心理学杂志》166：153-169）在青少年饮酒行为中发现的基因-环境相关性，这种相关性基于同伴的差异选择。对 490 对 MZ 和 336 对同性别 DZ 双胞胎样本的研究结果在方向上与假设一致，尽管数量上微不足道。然而，这种一致性似乎完全取决于样本中的女性双胞胎。
