Recall bias is a concern with which type of self-reported measure?

• A. Global Rating Scale (GROC)
• B. Region-specific measures
• C. Disorder-specific measures
• D. Objective laboratory measures

Answer: (A)

Recall bias shows up when a measure relies on remembering past states, and people’s memories aren’t perfectly accurate. A Global Rating of Change asks patients to rate how much their condition has changed since the start of treatment, which means they must recall their baseline symptoms and functioning and judge the amount of change. Memories can be distorted by the current state, mood, or outcomes, so this self-report is especially vulnerable to recall bias. Region-specific and disorder-specific measures typically assess current status or recent experiences rather than past change, so they’re less driven by retrospective memory. Objective laboratory measures aren’t based on recall at all, so they’re not subject to recall bias in the same way.
