The textbook “Fundamentals of Psychotherapy” by Gayane Shaverdyan is a unique contribution to Armenian-language psychological literature. It stands out not only for its structural completeness but also for the scientific and methodological approaches that allow psychotherapy to be viewed as a comprehensive scientific and practical field. The main value of this textbook lies in its integration of theoretical and applied aspects, making the material both accessible and practically relevant for students as well as practicing specialists. The book provides a detailed presentation of the main directions of psychotherapy — each examined through a combination of philosophical, psychological, and technical foundations. This structural approach enables the reader not only to master specific methods but also to understand their theoretical bases and practical boundaries. As a result, the reader acquires not just a mechanical toolkit, but a holistic worldview necessary for effective therapeutic work. The textbook also distinguishes itself by its linguistic style: it combines academic rigor with accessibility, while maintaining scientific credibility. This makes the book suitable both for use in higher education and in programs of professional retraining and continuing education. One of the key points emphasized by the author is the idea that psychotherapy cannot be reduced to the mere acquisition of techniques. Without an understanding of the conceptual and philosophical foundations, therapeutic practice risks becoming formal and superficial. In this sense, the book serves both as a selfreflection of the professional field and as guidance toward a deeper, more thoughtful professional mindset. “Fundamentals of Psychotherapy” is a scientifically grounded, methodologically consistent, and linguistically dynamic work that fills a significant gap in Armenian-language psychological literature. It is intended not only to educate but also to foster a culture of psychotherapeutic thinking and professional self-awareness. In this respect, the textbook serves simultaneously as an academic manual and as a guide for the further development of psychotherapy as both science and practice.
