Severity of Alcohol Dependence Questionnaire (SADQ)
Screens severity of alcohol dependence based on drinking habits and symptoms experienced after drinking.
Refer to the text below the questionnaire for more information about the SADQ and its interpretation.
SADQ is a self-administered 20-item questionnaire that evaluates severity of alcohol dependence. It is addressed to populations of problem drinkers: inpatient, outpatient and community-based treatment agency attenders.
It was originally formulated in by Edwards et al. in 1970 then subsequently redefined by Stockwell et al. in 1983. It takes up to 5 minutes to administer and it is easily scored.
The SADQ questionnaire may be used not only to screen alcohol dependence severity but also to predict the likelihood of achieving control drinking goals or predict alcohol withdrawal severity.
SADQ score | Interpretation | Next steps |
0 - 7 | Non-dependent | None for the moment, if there are concerns repeat screening at later date. |
8 - 15 | Mild dependence | Focus on guiding towards safe drinking with tightly monitored alcohol consumption. |
16 - 30 | Moderate dependence | Implement a period of abstinence. 80% may be able to control drinking once reintroduced but monitor carefully and ensure support is in place. 20% will not be able to control drinking and in case of relapse, permanent abstinence should be aimed for. |
31 - 60 | Severe dependence | Implements permanent abstinence. Look into treatment for alcoholism, establishing family and community support and treatment for potential physical and psychological comorbidities. |

Severity of Alcohol Dependence Questionnaire Explained
SADQ is a self-administered 20-item questionnaire that evaluates severity of alcohol dependence. It is addressed to populations of problem drinkers: inpatient, outpatient and community-based treatment agency attenders.
It was originally formulated in by Edwards et al. in 1970 then subsequently redefined by Stockwell et al. in 1983. It takes up to 5 minutes to administer and it is easily scored.
The SADQ focuses on readily quantifiable elements of alcohol dependence and the 20-items may be divided into five subscales, with 4 items in each:
SADQ subscales | Items |
Physical Withdrawal | 1. The day after drinking alcohol, I woke up feeling sweaty. 2. The day after drinking alcohol, my hands shook first thing in the morning. 3. The day after drinking alcohol, my whole body shook violently first thing in the morning if I didn't have a drink. 4. The day after drinking alcohol, I woke up absolutely drenched in sweat. |
Affective Withdrawal | 5. The day after drinking alcohol, I dread waking up in the morning. 6. The day after drinking alcohol, I was frightened of meeting people first thing in the morning. 7. The day after drinking alcohol, I felt at the edge of despair when I awoke. 8. The day after drinking alcohol, I felt very frightened when I awoke. |
Withdrawal Relief Drinking | 9. The day after drinking alcohol, I liked to have an alcoholic drink in the morning. 10. The day after drinking alcohol, I always gulped my first few alcoholic drinks down as quickly as possible. 11. The day after drinking alcohol, I drank more alcohol to get rid of the shakes. 12. The day after drinking alcohol, I had a very strong craving for a drink when I awoke. |
Alcohol Consumption | 13. I drank more than a quarter of a bottle of spirits in a day (OR 1 bottle of wine OR 7 beers). 14. I drank more than half a bottle of spirits per day (OR 2 bottles of wine OR 15 beers). 15. I drank more than one bottle of spirits per day (OR 4 bottles of wine OR 30 beers). 16. I drank more than two bottles of spirits per day (OR 8 bottles of wine OR 60 beers) |
Rapidity of Reinstatement | 17. I would start to sweat. 18. My hands would shake. 19. My body would shake. 20. I would be craving for a drink. |
Items 1 - 16 are scored:
- Almost never (0)
- Sometimes (1)
- Often (2)
- Nearly always (3)
Items 17 - 20 are scored:
- No (0)
- Slight (1)
- Moderate (2)
- A lot (3)
The SADQ questionnaire may be used not only to screen alcohol dependence severity but also to predict the likelihood of achieving control drinking goals or predict alcohol withdrawal severity.
Scores range from 0 to 60, with results greater than 30 correlating with clinician’s rating of severe alcohol dependence.
SADQ score | Interpretation | Next steps |
0 - 7 | Non-dependent | None for the moment, if there are concerns repeat screening at later date. |
8 - 15 | Mild dependence | Focus on guiding towards safe drinking with tightly monitored alcohol consumption. |
16 - 30 | Moderate dependence | Implement a period of abstinence. 80% may be able to control drinking once reintroduced but monitor carefully and ensure support is in place. 20% will not be able to control drinking and in case of relapse, permanent abstinence should be aimed for. |
31 - 60 | Severe dependence | Implements permanent abstinence. Look into treatment for alcoholism, establishing family and community support and treatment for potential physical and psychological comorbidities. |
Factor analysis yields single main factor accounting for 53 percent of variance and test-retest reliability of 0.85.
