Previous Step Next Protocol Translation and CRF Design Common CRF Design Errors Knowledge Check 30-45 minutes Foundational Step 3 of 3 Flip Cards Knowledge Check 3 / 3 Flip Cards Knowledge Check Listen Why are vague labels problematic? Users may interpret them differently What is a major disadvantage of excessive free-text fields? They reduce standardization and make analysis more difficult What does poor longitudinal structure mean? Repeated measurements are not properly organized by participant, visit, or time point A study collects a participant's favorite color even though it is unrelated to any study objective, safety assessment, or operational requirement. Which error does this represent? Unnecessary variable collection Why should measurement units be displayed directly on CRFs? To guide users to enter values in the correct unit and prevent ambiguity during analysis. Which activity should occur before implementing a substantially modified electronic CRF Testing and appropriate review/approval Why is CRF testing necessary? Testing identifies usability problems, incorrect validation rules, broken branching logic, data-entry issues, and other defects before the CRF is used for actual study data collection.
