The present article concentrates on the way of working out the program of effective intervention of professional reflection in psychology students. Five stages of study are presented. In the first step, in the literature review the designation of professional reflection was defined as a set of structure components: prognostic thinking, reflexivity, positive professional identity and agency. In the second step, in the empirical studies the external and internal factors of professional reflection were selected and examined among a group of professional psychologists (N=54). The analysis of empirical data of professional reflection factors and the level of its formation in psychology professionals made it possible to clearly identify the basic conditions for the intervention program «Professional reflection development» and its effect among psychology students. Only twenty five students (N=25) were self-selected in a 12-week intervention program forming an intervention group (IG). There are four studies of the program: cognitive, personality-related, motivational and emotional-volitional. All of them contain interaction, workshops, webinars, and art-cases. Remaining students (N=28) formed a control group (CG). The results obtained in both student groups and differences between them were further analyzed and explained.
