The purpose of this study was to examine the characteristics that distinguish children with behavior disorders who drop out of psychotherapy treatment from those who remain in treatment. The sample included 379 children (268 male and 111 female) who were diagnosed with a behavior disorder at Dallas County Mental Health/Mental Retardation (MH/MR), a community mental health clinic in Dallas, Texas. The results indicated that certain characteristics increased the likelihood that a child would drop out of therapy, including reliance on aid, the presence of maternal psychopathology, and more severe externalizing and internalizing behaviors. This study also found that younger children with behavior disorders had a greater probability of dropping out of treatment. Minority status, gender, parent marital status, and referral source were not found to be associated with dropping out of treatment. Future studies should focus on specific interventions that clinicians could employ to deter premature termination from treatment.
