This question pertains to Domain V: Strategies for Facilitating Recovery, which includes understanding evidence-based practices (EBPs) and their criteria. The CPRP Exam Blueprint states that “evidence-based practices are established through rigorous research, with findings supported by multiple, high-quality investigations demonstrating effectiveness.” The question tests knowledge of what constitutes a key criterion for an EBP, focusing on the scientific validation process.

Option B: For a practice to be considered evidence-based, its findings must be supported by additional investigations, meaning multiple, rigorous studies (e.g., randomized controlled trials) that replicate and confirm the practice’s effectiveness. This is a foundational criterion for EBPs in psychiatric rehabilitation, ensuring reliability and generalizability.

Option A: A fidelity scale measures adherence to an EBP’s protocols but is a tool for implementation, not a criterion for establishing the practice’s evidence base.

Option C: Non-contradictory findings are desirable but not a primary criterion; some variation in results is expected, and the focus is on overall evidence from multiple studies.

Option D: Implementation within service programs is an outcome of an established EBP, not a criterion for determining its evidence-based status.
