A validated questionnaire is not automatically a diagnostic verdict in every population.
A Brazilian study evaluated a Portuguese self-report dependence questionnaire in 179 chronic hypnotic users. It supported several psychometric properties across domains such as problematic use, preoccupation, noncompliance and withdrawal.
Most participants were women, and the sample included benzodiazepine and Z-drug users. Cross-validation would be needed before assuming identical performance in other languages, high-dose groups or different clinical settings.
Identify the version, target population and scoring purpose. A questionnaire measures reported experiences; it does not directly prove acute intoxication, diversion or an inability to taper. Corroborate the relevant clinical and medication history before translating a score into an individual forensic conclusion.
