Problem. Problem representation is a crucial element in novice and experts problem solving process, studies show. We've studied clients' problems representation from the psychotherapist’s point of view for better understanding their effective work and professional development.

Sample. Two groups took part in our research: novices (up to 5 years experience) and experts (over 10 years of experience).

Methods. The research is qualitative methodology oriented. We used semi-structured interview to collect data. Its’ macrostructure focused on getting an overview of the client's problem from psychotherapist’s perspective. And its microstructure is aimed at the reconstruction of details of the representation. For data analysis we used grounded theory by B. Glaser.

Results. Psychotherapists with different professional experience have different types of problem representation. For novices problems are often characterized as external obstacle and considered in the dichotomy of "norm-pathology", which should be eliminated / solved. Experts describe problems more detailed with the focus on their dynamic nature. They describe their activity as a clarification and understanding the problem.

Our research shows that there is a significant difference in clients' problem representation among psychotherapists on different stages of their professional development. It is connected with the way they perceive psychotherapeutic activity. Our future research will show how different types of problem representations are connected with specific psychotherapeutic goals and actions.
