7 items
Measures how heavy the protocol felt and whether taking part changed what was being measured. Reactivity is the standard threat to validity in ESM and is almost never measured — these items make it reportable. Pairs with the Burden Centre's observed-compliance estimates.
Usage
Used individually rather than summed. Administer at the end of a study, or weekly in longer protocols to track whether burden accumulates. Comparing self-reported burden against observed completion rates is more informative than either alone.
