Measures self-reported frequency of everyday cognitive slips and errors across memory, attention, and action. High CFQ scores are associated with stress, anxiety, neuroticism, and poor sleep. Useful for measuring cognitive side-effects of psychological disorders and interventions, and as a covariate in cognitive research.
Likert (0–4, never to very often) over the past 6 months; total 0–100
Higher scores = more cognitive failures. Freely available. CFQ scores are stable over time (trait-like) but also sensitive to state factors like stress and fatigue. Useful as a covariate or manipulation check in cognitive and clinical research.
