THE ADDICTION SEVERITY INDEX - RELIABILITY AND VALIDITY IN A DUTCH ALCOHOLIC POPULATION

The Addiction Severity Index (ASI) was evaluated for its psychometric qualities in a Dutch alcoholic population admitted to an addiction tre atment center in The Netherlands. Its factorial structure in this popu lation was found to be consistent with the established six factor stru cture of the ASI. Reliability analysis revealed that the homogeneity o f the subscales was acceptable with the exception of the Alcohol Scale . The six subscales were not highly intercorrelated. The results of th is study indicate that the ASI is a useful instrument for the assessme nt of several problems associated with alcoholism. However, the Alcoho l Scale appears to;be limited as a diagnostic and research instrument in the field of inpatient treatment of alcohol dependence in The Nethe rlands.
