In sum, there is considerable value in implementing screening instruments that are capable of detecting cannabis dependence or cannabis-related problems. Several short instruments have been developed and are available for routine use in general populations as well as in clinical settings. Despite of the high relevance, the number of research in this field is rather scarce. This review summarizes the psychometric properties of the four screening scales SDS, CUDIT, CAST and PUM by using peer-reviewed research to examine reliability and validity of these instruments in different samples. This overview may as well serve as a starting point for future research on the assessment of cannabis-related problems by identifying the major knowledge gaps.
