Final answer:
In evidence-based practice, psychologists use therapeutic tools backed by empirical research to ensure their therapy methods are scientifically validated.
Step-by-step explanation:
When psychologists who primarily provide therapy engage in evidence-based practice, they are using therapeutic tools whose effectiveness is supported by empirical research. This approach to therapy relies on scientifically validated methods and techniques that have been demonstrated to be effective through rigorous research and analysis. Clinical psychologists may utilize a range of therapeutic strategies, such as cognitive-behavioral therapy, which considers cognitive processes and behaviors, and these strategies are subject to empirical testing within the context of psychological theories. By adhering to evidence-based practice, therapists ensure that their interventions have a strong empirical foundation and are not based on pseudoscience, speculation, or subjective trial-and-error methods.
