Family cultural values that emphasize support, loyalty, and obligation to the family are associated with lower psychopathology in Hispanic/Latino/a youth, but there is a need to understand the implications of family cultural values for youth development in racially/ethnically heterogeneous samples. This study examined phenotypic associations between parent- and youth-reported family cultural values in late childhood on youth internalizing and externalizing symptoms in early adolescence, and whether family cultural values moderated genetic and environmental influences on psychopathology symptoms. The sample comprised 10,335 children (M_age=12.89 years; 47.9% female; 20.3% Hispanic/Latino/a, 15.0% Black, 2.1% Asian, 10.5% other) and their parents from the Adolescent Brain Cognitive Development (ABCD) Study, and biometric models were conducted in the twin subsample (n = 1,042 twin pairs; 43.3% monozygotic). Parents and youth reported on their family cultural values using the Mexican American Cultural Values Scale at youth age 11–12, and parents reported on youth internalizing and externalizing symptoms using the Child Behavior Checklist at youth ages 11–12 and 12–13. Greater parent- and youth-reported family cultural values predicted fewer youth internalizing and externalizing symptoms. Biometric models indicated that higher parent-reported family cultural values increased the nonshared environmental influences on externalizing symptoms whereas youth-reported family cultural values decreased the nonshared environmental influences on internalizing symptoms. This study highlights the need for behavior genetic research to consider a diverse range of cultural contexts to better understand the etiology of youth psychopathology.

强调对家庭的支持、忠诚和义务的家庭文化价值观与西班牙裔/拉丁裔/青少年较低的精神病理学相关，但有必要了解家庭文化价值观对种族/民族异质样本中青年发展的影响。这项研究探讨了童年晚期父母和青少年报告的家庭文化价值观与青少年青春期早期内化和外化症状之间的表型关联，以及家庭文化价值观是否调节了遗传和环境对精神病理学症状的影响。样本包括来自青少年大脑认知发展 (ABCD) 研究的 10,335 名儿童（男性_年龄= 12.89 岁；47.9% 女性；20.3% 西班牙裔/拉丁裔/a，15.0% 黑人，2.1% 亚洲人，10.5% 其他人）及其父母，生物识别模型在双胞胎子样本中进行（n = 1,042 对双胞胎；43.3% 同卵）。父母和青少年使用 11-12 岁青少年的墨西哥裔美国人文化价值观量表报告他们的家庭文化价值观，父母使用 11-12 岁和 12-13 岁青少年的儿童行为检查表报告青少年的内化和外化症状。父母和青少年报告的家庭文化价值观越高，青少年内化和外化症状就越少。生物识别模型表明，较高的父母报告的家庭文化价值观增加了对外化症状的非共享环境影响，而青少年报告的家庭文化价值观则减少了对内化症状的非共享环境影响。这项研究强调了行为遗传学研究需要考虑多种文化背景，以更好地了解青少年精神病理学的病因。
