Intervention Fidelity to VITAL Start (Video Intervention to inspire Treatment Adherence for Life) in a Randomized Controlled Trial Among Women Living with HIV in Malawi
Intervention effectiveness in a randomized controlled trial is attributed to intervention fidelity. Measuring fidelity has increasing significance to intervention research and validity. The purpose of this article is to describe a systematic assessment of intervention fidelity for VITAL Start (Video intervention to Inspire Treatment Adherence for Life)—a 27-minute video-based intervention designed to improve antiretroviral therapy adherence among pregnant and breastfeeding women. The intervention was delivered by Research Assistants (RAs) to 379 participants in a randomized controlled trial. Four fidelity domains were measured by self and observer ratings using checklists. The results showed that the RAs delivered the intervention with high adherence, dose, quality of delivery, and participant responsiveness. The authors conclude that intervention fidelity monitoring is essential for the validity of intervention research. Tapiwa A. Tembo, Christine M. Markham, Steven P.
