According to Prof. William Miller and Prof. Stephen Rollnick motivational interviewing (MI) is a client centered, directive, goal oriented method for enhancing internal motivation to change by exploring and resolving ambivalence. The principles of motivational interviewing are as follows: express empathy, develop discrepancy, avoid argumentation, roll with resistance and support self-efficacy. Motivational interviewing can be used as one of the psycho-social methods in long-term management of patients suffering from schizophrenia. It can be used to solve the current problems that appear in the treatment of chronic psychotic patients. However, the main use of MI in this group of patients is to improve adherence concerning pharmacotherapy. In the group of patients with the diagnosis of schizophrenia, certain modifications of this method have to be done to overcome such problems as lack of insight, negative symptoms and cognitive deficits. The main objective of this paper is to present the basic principles of MI in the context of therapy of persons with psychotic disorders. Another issue raised, is the theoretical positioning of MI between other types of short-term therapeutic methods. In the summary, we discuss the results of studies on the effectiveness of the MI application in comparison with other forms of therapeutic methods created to improve adherence in the treatment of patients with psychotic disorders.
