These clusters indicate how closely various ideas in psychotherapy supervision are connected by theme groupings of study subjects. Within the larger literature, the network visualization aids in the identification of core study domains, peripheral issues, and developing subfields. Apart from network visualization, temporal trends in psychotherapy supervision study were investigated using overlay visualization. This method lets keywords have a color gradient depending on their average year of publication, therefore enabling an easy chronological mapping of research advances. By means of this approach, more recent trends (e.g., cultural humility, telehealth monitoring) can be separated from earlier basic themes (e.g., supervision models, competency), therefore offering a dynamic viewpoint on the development of the profession. A citation analysis was conducted to pinpoint the most referenced authors and works in psychotherapy supervision research, therefore evaluating the impact and influence of important publications. Highly cited works show fundamental research or major contributions that have shaped the field. Leading scholars, historic theoretical models, and important debates that still shape modern supervision techniques are helped to be identified by this study [24. . This work offers a thorough, data-driven driven analysis of psychotherapy supervision research by combining these bibliometric approaches. The results emphasize theme links, support a more ordered knowledge of research trends, and provide insightful analysis for next studies on psychotherapy supervision. 3. RESULTS The bibliometric analysis of psychotherapy supervision research revealed significant trends and thematic developments over time. A total of 386 publications were retrieved from the Web of Science Core Collection, covering a broad spectrum of topics related to psychotherapy supervision. These publications included empirical studies, theoretical discussions, and systematic reviews, reflecting the multifaceted nature of supervision in psychotherapy training and professional development. The dataset contained 937 unique keywords, of which 139 met the minimum co- occurrence threshold (≥3 occurrences). The selection of a minimum threshold ensured that only frequently occurring and thematically relevant terms were included in the analysis, thereby enhancing the clarity and interpretability of the findings. The keyword co-occurrence network analysis identified four distinct thematic clusters, each representing a core research focus within psychotherapy supervision (Figure 1).
