Mercy Evaluation of MS Appropriately Valid

Clin Neuropsychol; ePub 2018 Jan 23; Merz, et al

Results of a recent study suggest appropriate construct validity of the Mercy Evaluation of Multiple Sclerosis (MEMS) for use with individuals with multiple sclerosis (MS), as well as provide support for previously established cognitive batteries. Archival data from individuals diagnosed with MS (n=378) by independent neurologists was examined. Cognitive domains assessed included processing speed and attention, learning, and memory, visuospatial, language, and executive functioning. A mean battery index was calculated to provide a general indicator of cognitive impairment within the current sample. Researchers found:

  • Overall performance across participants was found to be in the lower limits of the average range.
  • Results of factor analytic statistical procedures yielded a four-factor solution, accounting for 67% of total variance within the MEMS.
  • 4 neurocognitive measures exhibited the highest sensitivity in detecting cognitive impairment, constituting a psychometrically established brief cognitive screening battery, which accounted for 83% of total variance within the mean battery index score.
