<p>This study introduces a new perspective on developing problem conceptualization in cognitive-behavioral therapy. It is based on distinguishing and systematically applying approaches associated with idiographic and nomothetic contexts and contexts of discovery and justification. Case conceptualization is necessary to obtain a well-constructed therapeutic process, therefore, the practical aspect of the thesis lies in facilitating the improvement of its construction by indicating new methodological possibilities. Efforts to clarify concepts and make them more useful can be improved by distinguishing between the importance of different contexts related to discovery and justification. This includes understanding individual stages of conceptualization within idiographic and nomothetic contexts. This should be followed by their methodical implementation into the efficient process aiming to create an understanding of the problems that the patient is facing. The proposed, context-related aspect of conceptualization facilitates obtaining its fundamental objective, namely integrating the information concerning the patient as an individual being with the knowledge of psychopathology, the understanding of psychical phenomena and therapeutic procedures, into a coherent construct, which enhances the practical applicability of conceptualization.</p>
