Intervention fidelity in a translational study: lessons learned

Area of Science:

• Translational Science
• Health Services Research
• Behavioral Intervention Studies

Background:

• Intervention fidelity is crucial for the success of translational research, ensuring interventions are delivered as intended.
• Existing clinical settings, such as outpatient cardiac rehabilitation (CR), present unique challenges for implementing behavioral interventions.
• Traditional intervention fidelity strategies may not directly apply to translational research conducted in real-world clinical environments.

Purpose of the Study:

• To examine intervention fidelity strategies employed in a translational study.
• To identify and analyze lessons learned regarding intervention fidelity in a cardiac rehabilitation setting.
• To provide insights into adapting fidelity approaches for successful translational research.

Main Methods:

• A translational study involving a behavioral intervention delivered within an established outpatient cardiac rehabilitation (CR) program.
• Analysis of intervention fidelity components: design, training, delivery, monitoring receipt, and monitoring enactment.
• Comparison of fidelity strategies used in this translational study versus typical intervention studies.

Main Results:

• Fidelity components of design, training, and delivery differed significantly from standard intervention studies.
• Study design required adaptation to unique characteristics of the clinical environment.
• Existing CR staff, rather than research staff, delivered the intervention, impacting training and delivery fidelity.

Conclusions:

• Translational research necessitates flexible and novel intervention fidelity plans tailored to specific study contexts.
• Adapting design, training, and delivery is essential when implementing interventions in clinical practice settings.
• Monitoring receipt and enactment fidelity components showed similarities to usual intervention studies, focusing on participant behavior.
