Schizotypy and its associated features-negative schizotypy, disorganization, and positive schizotypy-are correlated with increased cannabis use. Yet, it is unclear whether cannabis users with schizotypy are at greater risk of developing cannabis problems. Individuals with elevated schizotypy may be particularly vulnerable to cannabis problems. It is important to understand this association given the unknown harms of chronic cannabis use. Data for these analyses were drawn from a larger investigation of cannabis use in adult romantic relationships. Participants were community adults (N = 366; M Age = 24.6, SD = 3.1) who reported regular use of cannabis. Participants completed baseline surveys measuring cannabis use frequency, problems, and schizotypy. Follow-up assessments of cannabis problems and frequency were completed 4-, 7- and 10-months post-baseline. Multiple regression was used to test the effect of schizotypy-measured using the Schizotypal Personality Questionnaire-Brief (SPQ-B, Raine & Benishay, 1995)-on cannabis use problems controlling for 30-day cannabis use. At baseline, disorganization and positive schizotypy were associated with cannabis use, primarily for women. Results revealed that with cannabis use frequency in the model, the Disorganization subscale of the SPQ-B predicted cannabis problems at baseline and all 3 follow-up assessments. Results are consistent with research suggesting that those exhibiting odd behaviors report more problematic cannabis use. Future research may further this line of inquiry with a focus on longitudinal, reciprocal relationships among schizotypy features, cannabis use, and cannabis problems.
分裂型特质及其相关特征——消极分裂型特质、紊乱和积极分裂型特质——与大麻使用增加相关。然而，尚不清楚有分裂型特质的大麻使用者是否有更大的风险出现大麻问题。分裂型特质较高的个体可能特别容易出现大麻问题。鉴于长期使用大麻的危害尚不清楚，了解这种关联很重要。这些分析的数据来自对成年恋爱关系中大麻使用情况的一项更大规模的调查。参与者为社区成年人（N = 366；年龄中位数 = 24.6，标准差 = 3.1），他们报告经常使用大麻。参与者完成了测量大麻使用频率、问题和分裂型特质的基线调查。在基线后4个月、7个月和10个月完成了对大麻问题和频率的随访评估。使用多元回归来检验用分裂型人格问卷简版（SPQ-B，雷恩和贝尼沙伊，1995年）测量的分裂型特质对控制30天大麻使用量后的大麻使用问题的影响。在基线时，紊乱和积极分裂型特质与大麻使用相关，主要是对女性而言。结果显示，在模型中纳入大麻使用频率后，SPQ-B的紊乱分量表在基线以及所有3次随访评估中都能预测大麻问题。结果与研究一致，表明表现出怪异行为的人报告的大麻使用问题更多。未来的研究可以进一步探讨这一研究方向，重点关注分裂型特质、大麻使用和大麻问题之间的纵向、相互关系。
