Background: The Alcohol Use Disorders
Identification Test (AUDIT) and the short Drug Abuse Screening
Test (DAST-10) are brief self-report screens for alcohol and drug
problems that have not been evaluated for use with psychiatric
patients in developing countries. This study was designed to
evaluate the factor structure, reliability, validity, and utility
of the AUDIT and the DAST-10 in an Indian psychiatric hospital.
Method: Consecutive inpatient admissions from
April to December 2001 were sampled. Patients were diagnosed with
substance use disorders or psychiatric disorders according to
ICD-10 criteria. All patients completed both the AUDIT and the
DAST-10 during their intake evaluation.
Results: Of the 2286 admissions to the hospital,
1349 were enrolled in the study (30% women); 361 patients (27%)
had primary substance use disorders and 988 patients (73%) had
primary psychiatric disorders. Both the AUDIT and the DAST-10
were unidimensional and internally consistent. Total scores
significantly differentiated the subsamples with primary
substance use from those with primary psychiatric disorders (p
< .0001). Using cutoff scores of >= 8 on the AUDIT and
>= 3 on the DAST-10, only 10% (N = 100) of the psychiatric
subsample exceeded either cutoff, whereas 99% (N = 358) of the
addiction treatment subsample exceeded 1 or both cutoffs. Within
the psychiatric subsample, 77% (N = 65) of the patients who were
identified as high risk on the AUDIT did not receive an
additional alcohol use disorder diagnosis at discharge, and 59%
(N = 16) of those identified as high risk on the DAST-10 did not
receive an additional discharge diagnosis of drug use disorder.
Conclusion: The AUDIT and the DAST-10
demonstrate strong psychometric properties when used in an Indian
psychiatric hospital. Routine use of these brief screens can
facilitate detection of substance use disorders among psychiatric
