Quantity-frequency questions accurately screen for hazardous drinking. A single alcohol screening question (SASQ) or questions on quantity and frequency are effective tools for identifying at-risk alcohol consumption in clinical settings.

Area of Science:

  • Addiction Medicine
  • Public Health
  • Clinical Screening

Background:

  • Screening for hazardous or harmful drinking is crucial for early intervention.
  • Traditional quantity-frequency (QF) questions can be lengthy and complex.
  • Accurate and efficient screening tools are needed for clinical settings.

Purpose of the Study:

  • To evaluate the accuracy of quantity-frequency (QF) questions in identifying hazardous or harmful alcohol consumption.
  • To compare the performance of different alcohol screening questions.

Main Methods:

  • Three groups were interviewed: emergency department patients (injury/illness) and community controls.
  • A single alcohol screening question (SASQ) was administered, followed by calendar-based drinking questions and diagnostic interview schedule (DIS) questions.

  • Hazardous drinking and current alcohol use disorders were defined using established criteria; receiver operating characteristic (ROC) curves were used for comparison.

    • Main Results:

    • The area under the ROC curve for SASQ was 0.81.
    • A question about average quantity alone had an ROC of 0.80.
    • The product of usual frequency and average quantity (QF product) showed the highest accuracy with an ROC of 0.85, performing consistently across groups.

    Conclusions:

    • The quantity-frequency (QF) product and average quantity questions demonstrated consistent performance in identifying hazardous drinking.
    • Single screening questions like SASQ, or questions on typical quantity or heavy drinking frequency, can be effectively used in clinical practice.
    • These findings support the use of brief, accurate screening tools for alcohol consumption in diverse clinical populations.
