Medication decision-making by persons with serious mental illness.

The Interaction Model of Client Health Behavior (IMCHB) has been established as a useful model in guiding research and development of individually tailored clinical interventions. The constructs of client singularity, client-provider interaction, and health outcomes guided an examination of medication decision-making by persons with serious mental illness (SMI). Client motivation is discussed as it relates to participation in the client-provider interaction and subsequent medication adherence and quality of life. Decisional control, the specific element of the client-provider interaction that affects medication decision-making, is considered in relation to consumer roles and responsibility for medication management. As psychotropic medications remain the single most effective treatment for reducing the active symptoms of psychosis, this look at medication decision-making may have significant implications for nursing.
