Given recent state legislation legalizing marijuana for recreational purposes and majority popular opinion favoring these laws, researchers at RAND developed the Protective Behavioral Strategies for Marijuana scale (PBSM) to identify strategies that may mitigate the harms related to marijuana use among those young people who choose to use the drug. The goal was to develop a psychometrically sound item bank for the PBSM and to create a short assessment form that minimizes respondent burden and time.
Quantitative item analyses revealed an item bank of 36 items, as well as a short form of 17 items, available for download below. Also provided is a scoring table for easy transformation from sum scores to IRT scale scores.
