Accuracy of self-assessment of the minimal record of disability in patients with multiple sclerosis.
We tested the validity of a self-administered version of the minimal record of disability (MRD) for multiple sclerosis (MS) by measuring the agreement level between patients' self-assessment and neurologists' independent ratings. 96 MS patients and 4 neurologists took part in the experiment; the agreement level was measured in terms of the intraclass correlation coefficient (ICC). On the Kurtzke functional system (FS) the ICC ranged from 0.26 in the sensory to 0.69 in the pyramidal function; a high concordance (ICC = 0.84) was found on the expanded disability status scale (EDSS). The ICC values were above 0.70 for most of the incapacity status scale (ISS) and environmental status scale (ESS) items. A modified, self-administered version of the MRD may represent a reliable instrument for obtaining a comprehensive profile of patients' abilities.
