Cognitive Failures Questionnaire

The Cognitive Failures Questionnaire (CFQ) is a 25-item self-report instrument designed to measure the frequency of everyday cognitive lapses and failures in memory, attention, and action slips. Developed by Broadbent and colleagues at the University of Oxford in 1982, the CFQ assesses subjective cognitive complaints in the general population and across diverse clinical and occupational settings. Higher scores reflect more frequent subjective cognitive failures and are associated with stress, fatigue, mood disturbance, and, in some populations, objective cognitive impairment.
