Turkish versions of two cannabis screening tools showed good reliability for both cannabis and synthetic cannabinoid users
The Turkish versions of the Cannabis Use Problems Identification Test (CUPIT) and Cannabis Problems Questionnaire (CPQ) showed good psychometric properties and worked for both cannabis and synthetic cannabinoid use disorder patients.
Quick Facts
What This Study Found
The CUPIT and CPQ questionnaires were validated in a Turkish clinical sample of 52 cannabis users and 45 synthetic cannabinoid users being treated for use disorders. Both instruments showed good internal consistency: CUPIT scored 0.89 and CPQ scored 0.87 (Cronbach's alpha).
The CUPIT and CPQ were strongly correlated with each other (r=0.76) and moderately correlated with the Cannabis Withdrawal Scale (r=0.63 and r=0.74 respectively), supporting convergent validity.
Principal component analysis supported a two-factor structure for the CUPIT. The finding that both tools worked for synthetic cannabinoid users is particularly relevant given the high prevalence of synthetic cannabinoid use in Turkey.
Key Numbers
CUPIT: alpha 0.89. CPQ: alpha 0.87. CUPIT-CPQ correlation: r=0.76. CUPIT-CWS correlation: r=0.63. CPQ-CWS correlation: r=0.74. Sample: 52 cannabis users, 45 synthetic cannabinoid users (all male outpatients).
How They Did This
Psychometric validation study of Turkish translations of the CUPIT and CPQ in 97 male outpatients with cannabis (n=52) or synthetic cannabinoid (n=45) use disorder. Analyses included principal component analysis, internal consistency (Cronbach's alpha), and correlational validity against each other and the Cannabis Withdrawal Scale.
Why This Research Matters
Cannabis and synthetic cannabinoids are widely used in Turkey, and clinicians need validated screening and outcome tools in Turkish. Demonstrating that these instruments work for synthetic cannabinoid users is important because synthetic cannabinoid use disorder is common in Turkey and may present differently from natural cannabis use disorder.
The Bigger Picture
The availability of validated screening tools in local languages is essential for clinical practice and research worldwide. The applicability to synthetic cannabinoid users is a practical advance, given that many countries face synthetic cannabinoid problems and few validated clinical tools specifically address these substances.
What This Study Doesn't Tell Us
Male-only sample limits generalizability. Relatively small sample size (97 total). Outpatient treatment-seeking population may differ from community samples. One CPQ subscale (CPQ-C) had low internal consistency (alpha 0.30). The study did not assess test-retest reliability.
Questions This Raises
- ?Would the tools perform similarly in female Turkish patients?
- ?Are there meaningful clinical differences between cannabis and synthetic cannabinoid use disorder that these instruments should capture?
- ?Can the low-reliability CPQ-C subscale be improved?
Trust & Context
- Key Stat:
- Both screening tools validated for synthetic cannabinoid users (alpha 0.87-0.89)

What do these levels mean? →Frequently Asked Questions
Why validate cannabis tools for synthetic cannabinoid users?
Synthetic cannabinoids produce similar but often more severe patterns of use disorder compared to natural cannabis. Having validated tools that work for both populations is important because in many countries (including Turkey), synthetic cannabinoid use is as common or more common than natural cannabis use.
What is the CUPIT?
The Cannabis Use Problems Identification Test is a brief self-report screening instrument designed to detect problematic cannabis use. It covers patterns of use, dependence symptoms, and related problems. The Turkish version showed good internal consistency (Cronbach's alpha 0.89).
