The Benzodiazepine Dependence Questionnaire (BDEPQ) reliably assesses benzodiazepine (BZD) dependence. This new scale accurately predicts withdrawal severity in regular BZD users.

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Pharmacology

Background:

  • Benzodiazepine (BZD) dependence is a significant clinical concern.
  • Existing assessment tools primarily focus on withdrawal symptoms, neglecting broader dependence aspects.
  • The Benzodiazepine Dependence Questionnaire (BDEPQ) was developed for comprehensive BZD dependence assessment.

Purpose of the Study:

  • To develop and validate the Benzodiazepine Dependence Questionnaire (BDEPQ).
  • To evaluate the BDEPQ's internal consistency, construct validity, and predictive ability.
  • To provide a reliable tool for assessing BZD dependence in general BZD-using populations.

Main Methods:

  • A cohort of 302 regular BZD users completed the BDEPQ and other measures.
  • Construct validity was assessed by comparing the BDEPQ with scales for depression, anxiety, sleep quality, neuroticism, and withdrawal.

Related Experiment Videos

  • A 3-4 month follow-up assessed the BDEPQ's predictive power for BZD consumption and withdrawal.

    • Main Results:

    • The BDEPQ demonstrated high internal consistency and stability over time.
    • Three subscales were identified, each exhibiting good internal consistency and temporal stability.
    • The BDEPQ effectively predicted the severity of benzodiazepine withdrawal symptoms.

    Conclusions:

    • The BDEPQ is a reliable and valid self-report instrument.
    • It is suitable for assessing benzodiazepine dependence in diverse BZD-using populations.
    • The BDEPQ offers a comprehensive approach beyond just withdrawal symptom assessment.
