Official title
Validation of a Personalized Physical Activity Algorithm Via Modified e-Delphi (InnovaMotion Project)
Overview
This study aims to validate a personalized physical activity algorithm for risk screening and individualized exercise prescription using a modified online Delphi process. International experts in physical activity and exercise will evaluate the algorithm's components over two rounds of questionnaires, with consensus defined as ≥70% agreement. If needed, a focus group will resolve any remaining disagreements. Validation of this algorithm may support safer, more effective autonomous exercise, promoting adherence, improved health outcomes, and population-level benefits.
Detailed description
Study Phases - eDelphi Validation of the APPA Algorithm
Phase 1 - Round 1 (Initial Online Questionnaire):
The first phase consists of an online survey in which international experts in physical activity and exercise will evaluate the components of the personalized physical activity algorithm for health risk screening and individualized exercise prescription. Experts will assess the relevance, clarity, and clinical appropriateness of each item. Feedback from this round will identify items requiring modification or clarification.
Phase 2 - Round 2 (Re-evaluation):
The second phase consists of a consecutive online survey round, in which experts will re-evaluate the revised algorithm components based on feedback from Round 1. Experts will have the opportunity to adjust their ratings. This phase aims to move items closer to consensus (≥70% agreement).
Phase 3 - Optional Focus Group (if needed):
If consensus is not reached on specific items after Round 2, an online focus group will be conducted to discuss and resolve remaining disagreements. This discussion will help refine the algorithm and ensure agreement on all components.
Primary outcome measures
- Expert consensus on algorithm components [Time frame: Up to 2 months]
