We investigated the effectiveness treatment for substance abusing youth at an innovative residential program in Canada, the Pine River Institute (PRI). We explored (a) whether pretreatment problems were predicted by individual differences; (b) what predicted
treatment progression; (c) the amount of improvement preto posttreatment; and (d) what predicted those improvements. From data from 148 youths, we found that (a) parental divorce and mental health issues were associated with pretreatment problems; (b) youths who attended PRI in more recent years progressed further through treatment; (c) improvements were significant and large; and (d) youths who progress further in treatment experience greater improvements.
