In a PAF column, should a linkage record allow multiple response items?

• A. Yes, multiple response items are allowed
• B. Only if the PAF column requires it
• C. No, never allow multiple response items
• D. It depends on the template

Answer: (C)

The key idea here is that a linkage record in a PAF column is meant to bind to exactly one response item. Allowing multiple response items would create a multi-valued linkage, which makes validation, scoring, and data retrieval unpredictable and harder to maintain. With a single binding, the relationship is deterministic: one linkage maps to one specific item, ensuring consistent behavior across imports, exports, and reporting. Even if a template or scenario might seem to require multiple items, the standard approach keeps things simple by enforcing a one-to-one link. If you need to represent multiple selections, handle that at a higher level—such as duplicating linkage records for each required item or using a design that supports multi-value responses—rather than allowing a single linkage record to point to several items. Therefore, a linkage record should not allow multiple response items.
