Abstract

Abstract Objective To assess psychometric properties of the Benzodiazepine Dependence Self-Report Questionnaire – Portuguese Version (BENDEP-SRQ-PV) in a sample of Brazilian chronic hypnotic users. Methods One hundred and seventy-nine chronic hypnotic users (benzodiazepines and Z-drugs) were recruited, attended a psychiatric evaluation, and answered the BENDEP-SRQ-PV. Factor structure, reliability, and influence of covariates (dependence diagnosis and type of drug consumed) were assessed in a structural equation modelling environment. Discrimination was assessed with receiver operating characteristic (ROC) plots and stability with the test-retest method. Results Participants, mostly women (91.6%), aged 51 to 64 years old, had been using hypnotics for an average of 34.8 months, with a mean defined daily dose of 0.72. Psychometric analysis demonstrated construct and criterion validity, reliability, and response stability. The factor structure was maintained as originally proposed: problematic use (ω = 0.73), preoccupation (ω = 0.74), lack of compliance (ω = 0.74), and withdrawal (ω = 0.93). Conclusion The BENDEP-SRQ-PV is an adequate measure of hypnotic dependence in the Brazilian population of chronic users. Our results support using the scale for follow-up in clinical and research applications and in correlational studies. (AU)
