According to Mullen, E. J., & Streiner, D. L. (2004) and Charman, D., & Barkham, M. (2005), the concept of evidence-based practice is crucial in providing the most effective treatments that are supported by scientific evidence. The Johns Hopkins Model contributes to this by creating a structured approach for practitioners to follow, ensuring that decisions are made scientifically and not just based on tradition or other non-evidence-based methods.
