Treatment utilization and personality organization among drug abusers in Sweden.

Treatment utilization and personality organization in a case-finding sample of 1824 drug abusers in the greater Stockholm area were assessed by using a standardized questionnaire, with the client's contact persons as informants. Level of personality organization was strongly associated, negatively with the number of concurrent treatment contacts, problems of coordination between concurrent treatment agents, and was positively correlated with agreement between treatment agents in the assignment of principal treatment responsibility and their opinions about the appropriateness of this assignment. Psychiatric ICD-9 diagnosis was not associated with any of these variables.
