ABSTRACT
We look again at possible reasons why there are few significant differences in the behavior of former clients sampled among groups and we search for factors that might explain outcomes. First to be examined are the backgrounds and characteristics of the clients to determine whether there are significant differences among groups. Second, possible differences in the groups are examined in terms of subsequent treatment and types of participation in NTA and ASA. Third, possible interpretations are analyzed through multivariate analyses. Finally, an analysis is made of the services actually received by the clients.
