reflects OMERACT’s principle of rigorously integrating qualitative and quantitative evidence throughout the decision-making process in Core Outcome Set development. This principle signifies a commitment to an evidence-driven, methodologically sound approach, where every decision is anchored in a comprehensive array of available data and collaboratively generated insights. By meticulously documenting each step, process, and methodological choice, OMERACT upholds a high standard of transparency and accountability, ensuring that decisions are valid, reproducible, and trustworthy.
Example
When selecting candidate instruments for a new Core Outcome Set, the OMERACT team follows the Careful/Conscientious principle by systematically reviewing both quantitative psychometric evidence (validity, reliability, responsiveness) and qualitative stakeholder feedback. All decisions, rationales, and methodological choices are recorded in a transparent log, enabling others to trace how each instrument was evaluated and chosen.
