Substance use and gambling participation during adolescence are correlated, both concurrently and over time. It is unclear, however, whether this association can be explained by common underlying genetic vulnerabilities or environmental factors. The present study explored the concurrent and longitudinal associations between substance use and gambling participation and their genetic and environmental underpinnings by late adolescence. Participants were 373 pairs of monozygotic and dizygotic twins. Self-reports of substance use and gambling participation were collected at Ages 17 and 19 years. Results showed concurrent associations between substance use and gambling participation as well as a small, but significant unidirectional longitudinal association over time from substance use to gambling participation. Common genetic factors largely accounted for the concurrent associations at Ages 17 and 19, as well as for the unidirectional longitudinal association between substance use and gambling participation. Substance use and gambling participation share a common genetic component that account for most of their concurrent and longitudinal links during late adolescence. However, these behaviors are also influenced by specific environmental factors. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
青少年时期的物质使用和赌博参与是相关的，无论是在当前还是随着时间的推移。然而，目前还不清楚这种关联是否可以用共同的潜在遗传脆弱性或环境因素来解释。本研究通过青少年后期探索了物质使用和赌博参与之间的当前和纵向关联及其遗传和环境基础。参与者是 373 对同卵双胞胎和异卵双胞胎。在 17 岁和 19 岁时收集了物质使用和赌博参与的自我报告。结果表明，物质使用和赌博参与之间存在当前关联，以及随着时间的推移从物质使用到赌博参与的微小但显著的单向纵向关联。共同的遗传因素在很大程度上解释了 17 岁和 19 岁时的当前关联，以及物质使用和赌博参与之间的单向纵向关联。物质使用和赌博参与共享一个共同的遗传成分，这解释了它们在青少年后期的大部分当前和纵向联系。然而，这些行为也受到特定环境因素的影响。
