The processes of change represent hidden or obvious activities and experiences which people use or rely on in attempts to change their problematic behaviour. They were conceptualised as one of two key dimensions of Transtheoretical model of change (Prochaska et al. 1992). Metatheoretical analyses performed by TTM authors showed that over 400 different psychotherapeutical interventions could be summarized to 10 basic processes of change. By these authors patients use them more or less, depending on the fact at which stage of change they are. This research was conducted in attempt to discover if there was a difference in specific use of processes of change related to diagnosis of psychiatrical patients. The aim was to determine whether there was a difference in usage of change processes among patients with different diagnoses and also to determine which processes were dominantly used. The usage was measured by Processes of change questionaire PCQ-2001 (by Gavrilov-Jerković) completed by 221 patients diagnosed as neurosis, psychosis and personality disorder. Cluster analysis showed 6 clusters of patients with similar profile of processes usage. Analysis of variance showed a significant diferrence between them (F=2,78; p=0,019). By crosstabulating dignosis and cluster-membership variables we gained the following results: psychotic patients are mostly members of General low processes usage cluster and cluster defined by Relying on emotions, social support and psychotropic medications. Patients from neurotic spectrum were distributed between 4 clusters. Precontemplation cluster was defined by higher usage of passive processes. Contemplation cluster was defined by higher nondiscriminant usage of all processes. Action cluster was defined by low usage of medication process and high usage of all processes. The Maintenance cluster was defined by high usage of all processes except medication, and the highest usage of active and reorganizing processes. Theoretical and practical implications of these findings will be discussed.
