Which information is required by most systems to specify data entry screens?
When designing or configuring data entry screens within an Electronic Data Capture (EDC) system, three critical components are required for each field:
Data Type -- Defines the nature of the data (e.g., text, numeric, date).
Prompt -- The label or question displayed to the user.
Response Format -- Specifies how the user enters or selects data (e.g., free text, drop-down, checkbox).
According to the GCDMP (Chapter: EDC Systems and Database Design), these three attributes form the logical data structure required to build and validate data entry interfaces. They ensure consistency in how information is captured, displayed, and validated during data entry.
While user roles (A) and help text (D) are system-level configurations, not field-level specifications, page numbers (C) relate to printed CRFs rather than digital data screens.
Therefore, option B (Data type, prompt, and response format) correctly identifies the essential information needed to define data entry screens.
