The Memory Failures Scale (MFS) measures memory failures that are minimally explained by attentional errors. As such, it is a measure of common memory failures that people tend to experience in everyday life and can be used as an assessment of cognitive impairment.

The MFS is in the public domain and special permission is not required to use it for any purpose. The MFS is highly correlated with, but distinct from, attention-related cognitive errors and has been validated using large student and community samples. The MFS has previously been used with a number of relevant measures, including the MAAS-LO, ARCES, SART, BPS, BDI-II, and ESS. The MFS is scored either by simple summation or by calculating item mean scores.


For more information on the MFS, please download our psychometrics PDF. And of course feel free to contact any of us if you have any questions about the use of the MFS or our research.
