Description / Type of Assessment:

The SADD is a 15-item self-reported questionnaire. It can also be used as a structured interview.

Primary use / Purpose:

The SADD was designed to assess alcohol dependence in the general adult substance-abusing population. As reported by the authors in the original publication (see above), the questionnaire was designed to be (i) suitable for patients seeking help with alcohol problems; (ii) a measure of current dependence; (iii) sensitive across the full range of dependence, (iv) sensitive to change over time, and (v) relatively free of socio-cultural influences.

Domains measured / Life Areas / Problems Assessed:

Alcohol dependence.


SADD is aimed at the adult substance-abusing populations, primarily on those who are from mildly to moderately alcohol dependent.
A version of the SADD has been validated for use with young offenders.
It is commonly used with male and female clients of substance abuse treatment programs, although some studies also have used the SADD with nonclinical samples.

Administration / Completion Time:

2-5 minutes.

Scoring Procedures:

The 15 items summed for a total score than can range from 0 to 45. Scale totals are interpreted as follows: 1-9 low dependence, 10-19 medium dependence, and 20 or greater high dependence.

Practicability / usefulness:

The SADD appears to have stability and validity as a measure of alcohol dependence, and can be used to assess alcohol dependence in clinical samples.
Probably the SADD can be used to measure change over time in alcohol dependence because its sensitivity across the full range of dependence, although there are no studies examining this issue.


Among relevant studies on the SADD, you can find a summary on a detailed review published by the Addiction Research Foundation. The ARF reviewed 9 studies on the SADD in this report.
