The characteristics and the validity of the Recent Status Scores (RSSs), the new
summary scores generated by the sixth version of the Addiction Severity Index
(ASI-6), are compared to the fifth version of the ASI summary scores, the
Composite Scores (CSs). A sample of 82 randomly selected patients from substance
abuse treatment programs were interviewed with the ASI-6, the ASI-5 and were
administered a validity battery of questionnaires that included measures
corresponding to each of the ASI domains. Each ASI-6 RSS was significantly
correlated with its corresponding ASI-5 CS. The intercorrelations among the RSSs
are low and none of these correlations were statistically different from the
intercorrelations among CSs. In five of the seven areas, the ASI-6 RSSs were more
highly correlated to the corresponding validity measures than were the ASI-5 CSs.
The ASI-6 offers more comprehensive content in its scales than do those derived
with earlier ASIs.
