The main study aim is to evaluate the efficacy of IICAPS for youth with serious and pervasive mental health problems that places them at risk for institutional placement, and test the hypotheses that children receiving IICAPS will be less likely to exhibit out-of-control behaviors and less likely to experience a psychiatric hospitalization and/or out-of-home placement during and up to six months post-discharge from services. The second study aim is to evaluate how the efficacy of IICAPS for youth with serious and pervasive mental health problems is achieved, with specific focus on parenting practices, parental problem solving techniques, and parental perception of the child.
