The TWEAK screening tool effectively identifies risk drinking in pregnant women. Direct administration to diverse socioeconomic groups enhances its utility for prenatal alcohol use assessment.

Area of Science:

  • Obstetrics and Gynecology
  • Addiction Medicine
  • Public Health

Background:

  • The TWEAK is a validated screening tool for identifying at-risk alcohol consumption.
  • Previous studies faced limitations in directly assessing minority and indigent pregnant women.
  • Direct administration may improve accuracy in diverse prenatal populations.

Purpose of the Study:

  • To evaluate the efficacy of the TWEAK when directly administered to pregnant women.
  • To assess the TWEAK's performance across different socioeconomic backgrounds.
  • To refine the TWEAK for optimal use in prenatal care settings.

Main Methods:

  • The study involved 135 pregnant women at Brigham and Women's Hospital.
  • The original TWEAK instrument, including two tolerance questions, was utilized.

  • Data was collected from participants enrolled in an alcohol use during pregnancy study.

    • Main Results:

    • The TWEAK demonstrated strong predictive ability for alcohol diagnoses and risk drinking when the first tolerance question (drinks to feel effects) was set at >2 drinks.
    • Adjusting the cut point to 2 drinks increased TWEAK sensitivity but decreased specificity and predictive ability.
    • Medical record assessment was less sensitive but more specific for identifying alcohol use in pregnant women.

    Conclusions:

    • The TWEAK shows significant promise as a screening tool for identifying at-risk drinking during pregnancy.
    • Further validation in diverse clinical populations is recommended.
    • Direct administration enhances the TWEAK's applicability in prenatal settings.
