With introduction of the concept of alcohol dependence syndrome, scales specifically to measure dependence were developed and used in clinical and research settings. 12 questions from The Severity of Alcohol Dependence Data Questionnaire were translated into the Iccal language and was administered to 70 patients referred to the deaddiction centre. The trans 'ated version showed good evidence of internal validity, criterion validity and external validity.

The primary purpose of this study was to provide a comprehensive assessment of the underlying factor structure of the Alcohol Dependence Scale (ADS). Secondary goals included assessing concurrent validity of the total ADS and subscales derived from the factor analyses with variables related to alcohol dependence and further evaluating the validity of two proposed dichotomously scored, reduced-item ADS measures. Responses to the ADS were obtained from participants who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for alcohol dependence in two large randomized clinical trials: COMBINE (Combining Medications and Behavioral Interventions Study; n = 1,335; 69% male) and Project MATCH (Matching Alcoholism Treatments to Client Heterogeneity; n = 1,666; 75% male). Both exploratory and confirmatory factor analyses were conducted, and validity coefficients were obtained. Across samples, analyses supported a correlated, three-factor solution representing l.

This study evaluated the psychometric properties of the 15-item alcohol Short Index of Problems (SIP) instrument and those of a newly constructed 15-item drug Short Index of Problems (SIP-D) instrument in 277 newly entered substance-abuse patients. The SIP is derived from the longer, 50-item Drinker Inventory of Consequences (DrInC), which was designed to assess adverse consequences of alcohol use. The SIP-D was constructed by substituting the term "drug use" for the term "drinking" in each SIP item. A 3-month recall interval was employed. Factor analyses of each of the instruments revealed similar solutions, with only one main factor accounting for the majority of variance. Nonparametric item response theory methods produced the same finding. Internal consistency reliability estimates for the SIP and SIP-D total scores were .98 and .97, respectively. Concurrent validity was demonstrated by examining the correlations of the total scores for each of the instrument.
