Overcoming the novelty effect on YouTube: visibility patterns in evidence-based psychotherapy videos—Findings of a long-term observational study in French-speaking countries

Our findings demonstrate that evidence-based videos can overcome the novelty effect commonly associated with YouTube when embedded in real-life therapeutic practices. This suggests a hybrid dissemination model-leveraging both digital platforms and offline clinical networks-may effectively bypass algorithmic limitations. Future research should investigate the generalizability of these findings to other healthcare domains and platforms, and further explore the mechanisms through which professional recommendation influences digital engagement.
