Tóm tắt

<i>Background/Aims:</i> Cannabis use is a growing challenge for public health, calling for adequate instruments to identify problematic consumption patterns. The Cannabis Use Disorders Identification Test (CUDIT) is a 10-item questionnaire used for screening cannabis abuse and dependency. The present study evaluated that screening instrument. <i>Methods:</i> In a representative population sample of 5,025 Swiss adolescents and young adults, 593 current cannabis users replied to the CUDIT. Internal consistency was examined by means of Cronbach’s alpha and confirmatory factor analysis. In addition, the CUDIT was compared to accepted concepts of problematic cannabis use (e.g. using cannabis and driving). ROC analyses were used to test the CUDIT’s discriminative ability and to determine an appropriate cut-off. <i>Results:</i> Two items (‘injuries’ and ‘hours being stoned’) had loadings below 0.5 on the unidimensional construct and correlated lower than 0.4 with the total CUDIT score. All concepts of problematic cannabis use were related to CUDIT scores. An ideal cut-off between six and eight points was found. <i>Conclusions:</i> Although the CUDIT seems to be a promising instrument to identify problematic cannabis use, there is a need to revise some of its items.
