The Pfeffer Functional Activities Questionnaire (FAQ) is an informant-rated measure of instrumental activities of daily living. It covers complex tasks such as finances, shopping, meal preparation, remembering appointments, and transportation. Total scores range from 0 to 30, with higher values indicating greater functional impairment.
Formula: FAQ total = sum of 10 informant-rated items (0-30).
FAQ has robust psychometric support and is widely used for functional characterization across MCI and dementia evaluations.
Higher FAQ totals indicate greater instrumental-function impairment and support higher-level care and safety planning.
Use when functional impact of cognitive decline is being evaluated, especially in memory-clinic or geriatric assessment contexts.
Scores rely on informant quality and can be influenced by social context, baseline role expectations, and informant burden.
For related assessments, see Lawton IADL, Katz ADL and CDR Global.
