Questionnaire data from the Colorado Alcohol Research on Twins and Adoptees (CARTA) were analyzed to explore the reliability of sibling responses to items from the CARTA Family Alcoholism History Questionnaire (FHQ) concerning parental drinking behaviors. Subjects included 142 pairs of male and female, twin and nontwin siblings who reported on paternal and maternal problem drinking. FHQ items were summed to produce drinking-problem scales for fathers and mothers. There was generally good concordance across sibling reports of parental problem-drinking symptoms. There was a significant gender difference in that male offspring were more in agreement about their mothers' drinking behavior, while female offspring were more in agreement about their fathers' drinking behavior. For the most part, objective items, such as having two or more drunk-driving arrests, were more reliable (paternal kappa total = .56, maternal = .66) than subjective items, such as being happy only when drinking (paternal = .24, maternal = -.03). This evidence for reliability of sibling reports about parental drinking does seem to validate the use of such questionnaire data in alcohol studies.
对来自科罗拉多双胞胎与领养者酒精研究（CARTA）的问卷数据进行了分析，以探究兄弟姐妹对CARTA家庭酗酒史问卷（FHQ）中有关父母饮酒行为项目的回答的可靠性。研究对象包括142对男性和女性双胞胎及非双胞胎兄弟姐妹，他们报告了父母的问题饮酒情况。FHQ项目得分相加得出父亲和母亲的饮酒问题量表。兄弟姐妹对父母问题饮酒症状的报告总体上具有良好的一致性。存在显著的性别差异，即男性后代对母亲饮酒行为的看法更一致，而女性后代对父亲饮酒行为的看法更一致。在大多数情况下，客观项目，如因酒驾被捕两次或以上，比主观项目，如只有在饮酒时才开心，更可靠（父亲的kappa值总计为0.56，母亲为0.66）（父亲为0.24，母亲为-0.03）。兄弟姐妹关于父母饮酒情况报告的可靠性证据似乎确实证实了在酒精研究中使用此类问卷数据的合理性。
