There is a well‐established link between substance use and four personality traits of anxiety–sensitivity, hopelessness, impulsivity, and sensation‐seeking. However, construct‐level models of personality may conceal indicator‐level personality–outcome associations. The current study aims to investigate evolution of the network constellation of personality and cannabis/alcohol use from early to late adolescence. Data comes from the longitudinal Co‐Venture cohort (N = 3800). Personality indicators, measured by Substance Use Risk Profile Scale (SURPS) items, and the frequency of cannabis/alcohol use were assessed at four consecutive years (13–17 years old). Network constellations of the SURPS items and cannabis/alcohol use were estimated using Bayesian Gaussian graphical models at four time points. Results highlighted the age‐specific associations between personality indicators and substance use. The positive role of the sensation‐seeking trait (e.g. attitude towards transgression) was constant, whereas the positive role of hopelessness indicators (e.g. not being enthusiastic about future) and the negative role of anxiety–sensitivity indicators (e.g. fear of having unusual body sensations) were more prominent at early adolescence. The current study provides a novel perspective on the network structure of personality and substance use in adolescence and suggests substance‐specific and age‐adjusted targets in intervention efforts. © 2020 European Association of Personality Psychology

人格和物质使用的网络星座：从青春早期到晚期的演变

物质使用与焦虑的四个人格特质之间有一个公认的联系，即敏感性，绝望，冲动和寻求感觉。但是，人格的建构水平模型可能会隐藏指标水平的人格-结果关联。当前的研究旨在调查从早期到晚期青春期人格和大麻/酒精使用的网络星座的演变。数据来自联合研究的纵向队列（N = 3800）。在连续四年（13-17岁）评估了通过物质使用风险概况量表（SURPS）项目测量的人格指标以及大麻/酒精使用的频率。使用贝叶斯高斯图形模型在四个时间点估算了SURPS项目的网络星座以及大麻/酒精的使用。结果强调了个性指标和药物使用之间特定年龄的关联。寻求感觉特质的积极作用（例如对犯罪的态度）是恒定的，而绝望指标的积极作用（例如对未来不热心）和焦虑敏感度指标的消极作用（例如害怕有异常的身体感觉） ）在青春期初期更为突出。当前的研究为青春期人格和物质使用的网络结构提供了新颖的观点，并提出了干预措施中针对特定物质和年龄调整的目标 对未来并不热衷）和焦虑敏感度指标的负面作用（例如，害怕有异常的身体感觉）在青春期早期更加突出。当前的研究为青春期人格和物质使用的网络结构提供了新颖的观点，并提出了干预工作中针对特定物质和年龄调整的目标 对未来并不热衷）和焦虑敏感度指标的负面作用（例如，害怕有异常的身体感觉）在青春期早期更加突出。当前的研究为青春期人格和物质使用的网络结构提供了新颖的观点，并提出了干预措施中针对特定物质和年龄调整的目标。©2020欧洲人格心理学协会
