What does a lack of treatment fidelity indicate in an evidence-based intervention?

• A. The intervention was well implemented
• B. Staff members showed consistent application of the intervention
• C. Intervention outcomes are not comparable to those of other organizations
• D. The intervention was successfully modified

Answer: (C)

A lack of treatment fidelity in an evidence-based intervention suggests that the intervention was not implemented consistently or as intended. This inconsistency can result in variability in the outcomes, making it difficult to compare those outcomes with those from other organizations or studies that adhered to the original intervention protocol. When treatment fidelity is compromised, it raises questions about the integrity of the intervention and whether the results are a valid reflection of its efficacy. Therefore, the statement indicating that intervention outcomes are not comparable to those of other organizations accurately reflects the implications of lacking treatment fidelity. The other choices relate to successful implementation or modification of the intervention, which would typically suggest a higher level of treatment fidelity, contradicting the premise of a lack of fidelity.
