Matching adolescents with a cannabis use disorder to multidimensional family therapy or cognitive behavioral therapy: treatment effect moderators in a randomized controlled trial.
BACKGROUND In a recent r and omized controlled trial ( Hendriks et al. , 2011 ) , multidimensional family therapy ( MDFT ) and cognitive behavioral therapy ( CBT ) were equally effective in reducing cannabis use in adolescents ( 13 - 18 years old ) with a cannabis use disorder ( n=109 ) . In a secondary analysis of the trial data , we investigated which pretreatment patient characteristics differentially predicted treatment effect in MDFT and CBT , in order to generate hypotheses for future patient-treatment matching . METHODS The predictive value of twenty patient characteristics , in the area of demographic background , substance use , substance-related problems , delinquency , treatment history , psychopathology , family functioning and school or work related problems , was investigated in bivariate and subsequent multivariate linear regression analyses , with baseline to month 12 reductions in cannabis use days and smoked joints as dependent variables . RESULTS Older adolescents ( 17 - 18 years old ) benefited considerably more from CBT , and younger adolescents considerably more from MDFT ( p<0.01 ) . Similarly , adolescents with a past year conduct or oppositional defiant disorder , and those with internalizing problems achieved considerably better results in  MDFT  , while those without these coexisting psychiatric problems benefited much more from CBT ( p<0.01 , and p=0.02 , respectively ) . CONCLUSIONS The current study strongly suggests that age , disruptive behavior disorders and internalizing problems are important treatment effect moderators of MDFT and CBT in adolescents with a cannabis use disorder . If replicated , this finding suggests directions for future patient-treatment matching in adolescent substance abuse treatment
