MOS Cognitive Functioning Scale

The MOS Cognitive Functioning Scale was originally developed in the Medical Outcomes Study (MOS). This scale measures a range of less severe, day-to-day problems in six aspects of cognitive functioning, including reasoning, concentration and thinking, confusion, memory, attention, and psychomotor. Impairment in cognitive functioning can have a major impact on quality of life and daily functioning and can also be a symptom of specific conditions, such as multiple sclerosis, Parkinson’s disease, or depression.

QualityMetric distributes multiple language translations of the six question version of the MOS Cognitive Functioning Scale. The scale is intended for adults 18 years of age and older and is available in a static (paper/pencil) mode of administration with a standard four-week recall period.

The reliability and validity of the MOS Cognitive Functioning Scale have been evaluated in bipolar disorder, HIV, major depression disorder, epilepsy, and insomnia, among others. A recent literature search yielded 20 citations in which the MOS Cognitive Functioning Scale had been used in studies, including two clinical trials.
