Presently, California's Community Treatment Project (CTP) may be granted its claim of relative success in rehabilitating "neurotic" male delinquents. But earlier, more extensive, success claims by CTP researchers have been justifiably questioned by outside researchers. The present findings provide a possible reason for the limited success of CTP. With the data from Jesness's Preston study, Costner's multiple indicator procedure, and stepwise multiple regression, there is no evidence that competence in interpersonal relations and social maturity are important in I-level classification. But intelligence and moral orientation explain substantial amounts of the variance in I-level. These findings are contrary to the emphasis in CTP and in I-level theory, the basis of CTP.
