Aim of this paper was to summarize the psychometric properties of four short screening scales to assess cannabis-related disorders or problems (SDS, CUDIT, CAST, PUM). A total of 12 studies from a variety of countries using diverse samples from general and specific user populations have been identified. While the SDS has been well studied in different samples, research on the other three instruments is limited. Psychometric properties of all scales varied depending on the study population and standards used for validity assessment, and therefore, comparisons between scales and studies are limited.
