Although Hispanics/Latinos constitute the largest ethnic minority group in the United States, there are few culturally and linguistically valid Spanish language clinical assessment instruments. This shortage is even more critical in the addictions field. This article presents the psychometric characteristics of two drug abuse screening instruments; the Drug Abuse Screening Test (DAST-10), and the Reduce Annoyed Guilty Start (RAGS) test that were translated into Spanish. Participants included 60 drug abusers, 35 alcohol abusers, and 127 individuals with no alcohol and/or drug problem. Results indicated that the Spanish versions of the two drug abuse screening instruments were reliable and unidimensional and differentiated drug abusers from non-substance abusers and from alcohol abusers.

Objective: To determine the validity and reliability of the Alcohol Use Disorders Identification Test (AUDIT) and Drug Abuse Screening Test (DAST) for detecting alcohol and drug use disorders, respectively, in a population with first-episode psychosis (FEP). Method: Subjects with FEP completed the AUDIT and DAST and were divided into groups according to the presence or absence of a Structured Clinical Interview for DSM-IV (SCID) diagnosis of either current alcohol or drug misuse. The data were analyzed to see whether AUDIT and DAST scores were predictive of SCID diagnosis. Results: Patients with alcohol-related SCID diagnoses and those with drug-related SCID diagnoses scored significantly higher on the AUDIT and DAST, respectively, than the group without the respective SCID diagnosis (P < 0.001 in both cases). The AUDIT functioned best with a problem drinking cut-off score of 10 (sensitivity, 85%; specificity, 91%). The DAST functioned best with a problem drug use cut-off score of 3 (sensitivity, 85%; specificity, 73%). The area under the receiver operating characteristic curve was 0.86 for the AUDIT and 0.83 for the DAST. Conclusion: The DAST and AUDIT may reliably identify FEP patients with substance abuse.

Carey KB; Carey MP; Chandra PS. Psychometric evaluation of the Alcohol Use Disorders Identification Test and Short Drug Abuse Screening Test with psychiatric patients in India. Journal of Clinical Psychiatry 64(7): 767-774, 2003. (35 refs.)

This study evaluated the factor structure, reliability, validity, and utility of the AUDIT and the DAST-10 in an Indian psychiatric hospital. 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. Of the 2286 admissions to the hospital, 1349 were enrolled in the study; 361 patients had primary substance use disorders and 988 patients 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 < .001). Using cutoff scores equal to or greater than 8 on the AUDIT and equal to or greater than 3 on the DAST-10, 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. 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 patients.

Teplin D; Raz B; Daiter J; Varenbut M; Tyrrell M. Screening for substance use patterns among patients referred for a variety of sleep complaints. American Journal of Drug and Alcohol Abuse 32(1): 111-120, 2006. (53 refs.)

Virtually all psychiatric and substance use disorders are associated with sleep disruption. Studies indicate that psychiatric disorders are related closely to chronic insomnia and that psychoactive substances have acute and chronic effects on sleep architecture. Several aspects of sleep are compromised in individuals taking these substances, ranging from difficulty initiating sleep to difficulty maintaining sleep and hypersomnia. Sleep disturbances are apparent in person taking psychoactive drugs or alcohol and have been found to persist long after withdrawing from these drugs. For some, sleep disturbance can be so severe as to reverse treatment success and precipitate relapse to addiction or dependence. There is increasing evidence that primary insomnia without a concurrent psychiatric disorder is a risk factor for later developing substance use disorders. Patients were asked to complete two brief screening tools, the Michigan Alcohol Screening Test and Drug Abuse Screening Test, to examine substance use patterns among patients referred for a variety of sleep complaints in a sleep disorders clinic. We found that patients who demonstrated a variety of sleep complaints were more likely to have alcohol and drug problems than those in the general populations.

Yudko E; Lozhkina O; Fouts A. A comprehensive review of the psychometric properties of the Drug Abuse Screening Test. Journal of Substance Abuse Treatment 32(2): 189-198, 2007. (24 refs.)

This article reviews the reliability and the validity of the (10-, 20-, and 28-item) Drug Abuse Screening Test (DAST). The reliability and the validity of the adolescent version of the DAST are also reviewed. An extensive literature review was conducted using the Medline and Psychinfo databases from the years 1982 to 2005. All articles that addressed the reliability and the validity of the DAST were examined. Publications in which the DAST was used as a screening tool but had no data on its psychometric properties were not included. Descriptive information about each version of the test, as well as discussion of the empirical literature that has explored measures of the reliability and the validity of the DAST, has been included. The DAST tended to have moderate to high levels of test-retest, interitem, and item-total reliabilities. The DAST also tended to have moderate to high levels of validity, sensitivity, and specificity. In general, all versions of the DAST yield satisfactory measures of reliability and validity for use as clinical or research tools. Furthermore, these tests are easy to administer and have been used in a variety of populations.
