Evidence-based intervention ensures that treatments are what?

• A. effective
• B. ineffective
• C. costly
• D. time-consuming

Answer: (A)

Evidence-based intervention means selecting treatments that have been shown to produce meaningful change in outcomes through research and real-world practice. The core idea is that interventions should lead to real improvements in the client’s performance and participation, not just be theoretically sound. Therefore, the best answer is that treatments are effective—they’ve demonstrated positive effects in studies and practice.

While cost or time may influence decisions, and some effective treatments can be resource-intensive, these factors do not define evidence-based practice. On the other hand, an intervention that is labeled ineffective would not have demonstrated beneficial outcomes, which is inconsistent with evidence-based care.
