Motivation and the stages of change among individuals with severe mental illness and substance abuse disorders.

A complicating factor affecting the treatment of individuals with coexisting substance use problems and serious mental illness is their motivation for change and how these interacting, chronic conditions affect the entire process of intentional behavior change. This selective review explores conceptual and assessment issues related to readiness to modify substance use and readiness to initiate behaviors helpful for managing mental illness in the search for a better understanding of patient motivation for change. The recent but limited research on motivation and stages of change among dually diagnosed patients indicates that these individuals appear to access and use an intentional behavior change process. However, it is not completely clear how this process works and what precise adaptations are needed to assess and to access motivation to change to encourage sustained behavior change in this population. Nevertheless, motivation and readiness to change are important dimensions that need to be addressed in treatment and research with dually diagnosed populations.
