Previous research has suggested that observed factors of cannabis use including use patterns, motives, and consequences are mirroring the same factors for alcohol use. As the prevalence of cannabis continues to grow, the ambiguous nature of a popularizing substance calls for more empirical approaches toward treating cannabis-related problems. Narrowing in on a flexible state of identity as opposed to inflexible states of behaviors show to promote long-lasting behavior change. While implementing this context with interventions, measures regarding a healthy identity with cannabis have yet to be explored. A measure that quantifies the extent a healthy identity with consuming cannabis was created, entitled the Safe Cannabis Consumption Identity Measure (SCCIM). A five-factor model based on previous literature was conceptualized. An Exploratory Factor Analysis along with a Confirmatory Factor Analysis was conducted on the baseline sample (n = 580), revealing a strong two-factor model. The two altering factors identified within the model were "Congruent Identity" and "Counter Identity". The measure demonstrated moderate concurrent and discriminant validity. Prospectively four weeks later, those that reported moderate cannabis use were recruited for a follow-up survey (n = 52), which was evaluated for test-retest reliability and predictive validity. The measure demonstrated sound test-retest reliability and predictive validity, predicting higher use of protective behavioral strategies and lower cannabis-related consequences and cannabis use altogether. By utilizing a psychometric model of identity toward cannabis use, the SCCIM aims to serve as a practical mechanism for cannabis use interventions.
