The ASUDS-R is a 123 item psychometric-based, self-report,
differential screening instrument, designed and normed for impaired
driving offenders. It is appropriate for clients 16 years or older,
and may be administered by self report or interview format. The
ASUS-R meets the needs of a self-report instrument that is an
essential component of a convergent validation approach to the
assessment of patterns and problems associated AOD (alcohol and
other drugs) use within impaired driving populations. The ASUDS-R
contains all of the scales of the Adult Substance Use
Survey-Revised.
The ASUDS-R assesses an individual's AOD use
involvement in ten categories of drugs, and measures the degree of
disruption that might result from the use of these drugs. Three
supplemental scales provide a differential assessment of disruptive
AOD use outcomes which are subscales of the general DISRUPTION
scale. The ASUDS-R provides a specific measure of the degree of
involvement in the use of alcohol, and a specific measure of
driving-risk attitudes and behaviors. There is an AOD use benefits
scale. It also provides a screen for emotional or mood adjustment
problems, a measure of social non-conformity, a measure of legal
con-conformity, a measure of defensiveness or resistance to
self-disclosure, and a scale to assess motivation and readiness for
treatment. It provides measures of AOD involvement and legal
conforming for the most recent six month period the client has been
in the community.
The ASUDS-R can be used to provide guidelines for
assessing levels of AOD problems, abuse and dependence. It can also
be used to provide referral guidelines for various levels and types
of services for impaired driving offenders. It can be used to assess
during and post-treatment changes.
Extensive construct validation
studies (e.g., perspective, criterion, concurrent, predictive) have
been done on the ASUDS-R scales, using several large samples of
impaired driving offenders. As well, for the ASUDS-R scales that are
cross-matched with the Adult Substance Use Survey-Revised (ASUS-R),
construct validation studies have been done on large samples not
specific to impaired driving offenders. Principal components
analyses and Cronbach alpha studies of each scale have demonstrated
optimal internal consistency reliabilites congruent with the item
size of respective scales. Scale independence has been demonstrated.
Simple linear and multiple linear studies have demonstrated strong
relationships between ASUDS-R scales and external criterion
variables (e.g., eternal measures of substance use involvement and
disruption, prior treatment, BAC levels, prior impaired driving
involvement, etc.). Simple linear relationships between the ASUDS-R
scales and perspective variables (age, gender, ethnicity, marital
status) support hypotheses around these relationships. The User's
Guides for the original ASUDS and ASUS-R provide a detailed summary
of scale construct validation studies.
The ASUDS-R is available in a paper-pencil and automated version.
