“…They reduced their drug use steadily between intake and 12 months, and maintained relatively low levels of internalizing and externalizing symptoms over the long term. Previous studies show that lower risk in terms of limited family alcohol and drug history, better family functioning, and lower levels of comorbid psychopathology predicts better treatment outcomes (Babor et al, 1992;Ball et al, 1995;Crowley, Mikulich, MacDonald, Young, & Zerbe, 1998) and less chronic substance abuse and related problems in adulthood (Duncan, Alpert, Duncan, & Hops, 1997). Although these youth are at elevated risk due to their juvenile justice involvement, these results corroborate findings from recent studies suggesting that drug abuse and delinquency may be discrete factors, and that the relationship between substance use and criminal activity among youth may be more dynamic than some have proposed (Farabee, Shen, Hser, Grella, & Anglin, 2001;Paradise & Cauce, 2003).…”
