Ninety adult participants with schizophrenia or schizoaffective disorder were assigned to stay on polypharmacy or to switch to monotherapy. Half of these participants were receiving combinations of non-clozapine oral antipsychotics and half were receivi...

In this study we examine two assumptions that underlie the hypothesis that the outcomes of children with emotional disturbances are negatively affected by the loss of access to mental health services during their transitions to adulthood. The first is that children access mental health services during the pre-transition years, and the second is that these services are effective in reducing poor outcomes. We tested these assumptions using children who lost Medicaid enrollment between their 18th a...

This article identifies the arrest trajectories of youth from ages 12 through 24 years old and tests hypotheses derived from Moffitt’s developmental taxonomic theory of crime concerning the impact of various emotional disturbances on the specific trajectories of the youth involved. The study uses exclusively administrative data sets and includes a gender and racially diverse sample of 10,360 youth (30.7 % females) who were arrested at least once between ages 12 and 24 in the early 2000s. Latent ...

It details the results of analysis of FY 2007–2008 pharmacy claims data using these indicators that enabled the Program to identify practices and prescribers that required targeted interventions. The m...
