Özet

Cannabis and synthetic cannabinoids are widely used illicit substances in Turkey. The Cannabis Use Problems Identification Test (CUPIT) is a brief self-report screening instrument for detection of problematic cannabis use, whereas the Cannabis Problems Questionnaire (CPQ) is a measure for cannabis treatment outcome. The aim of this study was to evaluate the psychometric properties of the CUPIT and CPQ among Turkish male outpatients with cannabis (n = 52) and synthetic cannabinoid (n = 45) use disorder. Participants were evaluated with the CUPIT, the CPQ, and the Cannabis Withdrawal Scale (CWS). Principal Component Analysis (PCA) supported two-factor construct validity for CUPIT. Cronbach’s alpha was 0.84 for CUPIT-A factor, 0.83 for CUPIT-B factor, and 0.89 for CUPIT, when considered as a unidimensional scale. Cronbach’s alpha was 0.82 for CPQ-A factor, 0.73 for CPQ-B factor, 0.30 for CPQ-C, and 0.87 for CPQ, when considered as a unidimensional scale. The CUPIT and the CPQ were moderately correlated with the CWS (r = 0.63 and r = 0.74, respectively), whereas the CUPIT and the CPQ were strongly correlated with each other (r = 0.76). The Turkish version of the CUPIT and the CPQ can effectively identify substance use problems and treatment outcome, respectively, among outpatients with cannabis or synthetic cannabinoid use disorder.
