Identifying adolescents at risk for marijuana use who can be targeted for intervention efforts is critical. Certain personality traits are strongly associated with substance use, including marijuana use. We investigated the associations of impulsivity (and its subscales sensation seeking and lack of planning), aggression, and neuroticism with marijuana use (lifetime and frequency of past 12-month use) in a national sample of adolescents.
We used data from the National Comorbidity Survey: Adolescent Supplement, a nationally representative, cross-sectional study of 8495 U.S. adolescents aged 14 to 18 years. We calculated adjusted prevalence ratios and odds ratios to assess associations of the five personality scales with lifetime use and frequency of past 12-month use and examined gender as a potential moderator of these associations.
Each of the personality traits was positively associated with lifetime use (all p < 0.001). Impulsivity (the total scale and both subscales) and aggression (all p < 0.05) were positively associated with frequency of past 12-month use. The neuroticism-lifetime use association was stronger among girls (p < 0.001) than boys (p < 0.05), and the associations of impulsivity and lack of planning with frequency of use were significant only among girls, with moderate female users reporting higher levels of the personality scales than infrequent users (both p < 0.01).
Our study highlights the potential importance of identifying personality traits, specifically disinhibition-related traits such as impulsivity and aggression, to reduce and prevent adolescent marijuana use.
识别有大麻使用风险的青少年，以便针对其进行干预至关重要。某些人格特质与物质使用密切相关，包括大麻使用。我们在一个全国性的青少年样本中，研究了冲动性（及其子量表寻求刺激和缺乏计划性）、攻击性和神经质与大麻使用（终生使用情况及过去12个月的使用频率）之间的关联。
我们使用了来自全国共病调查：青少年补充调查的数据，这是一项对8495名年龄在14至18岁的美国青少年进行的具有全国代表性的横断面研究。我们计算了调整后的患病率比和优势比，以评估这五个人格量表与终生使用情况及过去12个月使用频率之间的关联，并将性别作为这些关联的潜在调节因素进行了研究。
每种人格特质都与终生使用情况呈正相关（所有p<0.001）。冲动性（总量表及其两个子量表）和攻击性（所有p<0.05）与过去12个月的使用频率呈正相关。神经质与终生使用情况的关联在女孩中（p<0.001）比在男孩中（p<0.05）更强，冲动性和缺乏计划性与使用频率的关联仅在女孩中显著，中度使用大麻的女性报告的人格量表得分高于不常使用的女性（两者p<0.01）。
我们的研究强调了识别个性特质，特别是与抑制解除相关的特质，如冲动性和攻击性，对于减少和预防青少年大麻使用的潜在重要性。
