Internalization of college substance use culture refers to the degree to which an individual perceives the use of that substance to be an integral part of the college experience. Although there is a growing literature characterizing this construct for alcohol, the present study describes the development and validation of a new measure to assess the internalization of the college marijuana use culture, the Perceived Importance of Marijuana to the College Experience Scale (PIMCES).
We recruited a large, diverse sample (N = 8,141) of college students from 11 participating universities. We examined the psychometric properties of the PIMCES and evaluated its concurrent validity by examining its associations with marijuana-related outcomes.
A single-factor, eight-item PIMCES demonstrated good model fit and high internal consistency (Cronbach's α = .89) and was correlated with marijuana user status, frequency of marijuana use, marijuana consequences, and injunctive norms.
Overall, the PIMCES exhibits sound psychometric properties. The PIMCES can serve as a possible mediator of the effects of personality and other factors on marijuana-related outcomes and may be a promising target for marijuana interventions.
大学生物质使用文化的内化是指个体将该物质的使用视为大学生活不可或缺一部分的程度。尽管有越来越多的文献对酒精使用的这一概念进行了描述，但本研究介绍了一种新的测量工具——大麻对大学生活的感知重要性量表（PIMCES）的开发与验证，该量表用于评估大学生大麻使用文化的内化情况。
我们从11所参与研究的大学中招募了一个多样化的大学生大样本（N = 8141）。我们检验了PIMCES的心理测量特性，并通过考察其与大麻相关结果的关联来评估其同时效度。
一个单因素、包含8个条目的PIMCES显示出良好的模型拟合度和较高的内部一致性（克朗巴哈α系数 = 0.89），并与大麻使用状况、大麻使用频率、大麻使用后果以及禁令规范相关。
总体而言，PIMCES具有良好的心理测量特性。PIMCES可能是人格及其他因素对大麻相关结果产生影响的一个中介变量，并且可能是大麻干预措施的一个有前景的目标。
