Abstract
In this study we present the addiction severity profile in a sample of 202 cocaine addicts, using the composite scores for each area of the EuropASI (European version of the ASI), which are compared with the severity ratings obtained through interviewers' subjective assessments. The results showed that the areas of the EuropASI which reflected the greatest severity according to the composite scores were, in the following order: employment/support, family/social situation, use of alcohol and psychiatric state. The results obtained with the composite scores show discrepancies with those obtained from the severity rating. Statistically significant differences were found in the areas of alcohol (Z = −6.205; p < 0.001), drugs (Z = −11.902; p < 0.001), family/social (Z = −6.915; p < 0.001) and psychiatric status (Z = −6.651; p < 0.001). The results call into question the reliability and validity of severity ratings obtained through interviewers' subjective assessments. For diagnosis and research, a more objective appraisal is recommended, using composite scores, since severity ratings depend totally on the interviewer's judgement, and do not appear to constitute a sound measure for estimating therapeutic change.
