背景和目的：青春期的药物使用可能导致药物使用障碍和其他社会心理问题的发展。对于在较早年龄使用药物的个人和在青春期大量使用药物的人来说，这些负面结果尤其可能发生，这些行为在发生药物使用障碍风险较高的青少年中更为常见，例如有药物使用障碍家族史 (FH +) 的青少年。 FH+ 青少年中更多的感觉寻求和更多地接触压力源等因素可能会影响这些关联。因此，本研究的目的是探讨 FH+ 青少年青春期前的感觉寻求以及青春期早期至中期暴露于压力源对青春期中期累积物质使用的相对和独特的贡献。 方法：这些分析纳入了参与一项正在进行的纵向研究的总共 167 名 FH+ 青少年（12-15 岁），其中大部分是西班牙裔 FH+ 青少年。使用了涵盖大约 2.5 年的每两年一次的参与者数据。比较了自我报告的感觉寻求、压力源暴露和物质使用。结果：青春期前较高的感觉寻求和青春期早期至中期较多的压力源暴露均与 15 岁时的物质使用相关。这些因素将物质使用者与非使用者区分开来，也与物质使用水平相关。结论：在高危青少年中，较高的感觉寻求和暴露于压力源均与 15 岁时物质使用相关。此外，这些因素可以区分在这个重要的发展时期物质使用量较大的青少年。 (C) 2017 年由爱思唯尔有限公司出版。
Background and aims: Substance use during adolescence can lead to the development of substance use disorders and other psychosocial problems. These negative outcomes are especially likely for individuals Who use substances at earlier ages and those who engage in heavier use during adolescence, behaviors which are both more common among youth at higher risk for developing a substance use disorder, such as those with a family history of substance use disorders (FH +). Factors such as increased sensation seeking and greater exposure to stressors among FH+ youth may influence these associations. Therefore, the aim of this study was to examine the relative and unique contributions of sensation seeking during preadolescence and exposure to stressors during early to mid-adolescence to cumulative substance use by mid-adolescence among FH+ youth.Methods: A total of 167 mostly Hispanic FH+ youth (ages 12-15) who were participating in an ongoing longitudinal study were included in these analyses. Participants' data from biennial waves covering approximately 2.5 years were used. Self-reported sensation seeking, exposure to stressors, and substance use were compared.Results: Higher sensation seeking during preadolescence and greater exposure to stressors during early to mid adolescence were both associated with substance use by age 15. These factors differentiated Substance Users from Non-Users, and also related to level of substance use.Conclusions: Elevated sensation seeking and exposure to stressors are both associated with substance use by age 15 among high-risk youth. Additionally, these factors can distinguish youth who develop heavier substance use during this important developmental period. (C) 2017 Published by Elsevier Ltd.
