1. Perceived Importance of Marijuana to the College Experience Scale (PIMCES)

Year: 2017

Pearson, Matthew R.; Kholodkov, Tatyana; Gray, Matt J.; Marijuana Outcomes Study Team

The 8-item PIMCES was developed to assess the degree to which marijuana is perceived to be an integral part of the college experience. Based on the 15-item College Life Alcohol Salience Scale (CLASS) measure (Osberg et al, 2010), the developers dropped 7 items and then replaced the words "drinking" or "alcohol use" with "marijuana" or "marijuana use" in the others. Respondents rate their agreement with each of the final 8 items on a 5-point Likert-type scale ranging from 1 (strongly disagree) to 5 (strongly agree). Items include statements like, "Parties or social gatherings with marijuana are an integral part of college life," "I would prefer it if my college was not considered a marijuana school," or "College is a time for experimentation with marijuana."

Population studied:College students
Instrument Type:Self-administered questionnaire
Validity/Reliability:With respect to construct validity, the PIMCES was significantly associated in predicted directions with marijuana use and outcomes. The PIMCES also demonstrated good model fit and high internal consistency (Cronbach's alpha = 0.89), and was correlated with marijuana user status, frequency of marijuana use, marijuana consequences, and injunctive norms (Pearson et al, 2017).
