Psychoses are among the most common and serious psychiatric disorders. Currently, the most effective treatment for psychoses involves the use of antipsychotic or neuroleptic medications. Unfortunately, pharmacologic regimens often do not achieve their goals because of poor medication adherence. Nonadherence to antipsychotic treatment is a considerable public health problem that leads to myriad clinical and economic burdens, including psychotic relapse, increased clinic and emergency room visits, and rehospitalization.
