The Severity of Alcohol Dependence Questionnaire (SADQ or SAD-Q) is a 20 item clinical screening tool designed to measure the presence and level of alcohol dependence[1].

It is divided into 5 sections:

  • Physical withdrawal symptoms
  • Affective withdrawal symptoms
  • Craving and relief drinking
  • Typical daily consumption
  • Reinstatement of dependence after a period of abstinence[2].

Each item is scored on a 4-point scale, giving a possible range of 0 to 60. A score of over 30 indicates severe alcohol dependence.[3].

Some local clinical guidelines use the SADQ to predict the levels of medication needed during alcohol detoxification[4]
