interrater reliability calculated at three time periods was calculated
at 0.97. Interrater intercorrelations were quite high, with the
lowest correlation being 0.86 (item 8, nasal swab). Inter-item correlations
were obtained including the alpha coefficient. Alpha coefficients
were 0.43, 0.65, and 0.65 for CNC scores done at 1, 8, and 16 weeks
post injury (Rappaport, 1992).
order correlation between CNC and DRS scores was 0.69 (p<.02).
The correlation between CNC and the degree of abnormality of the
multisensory (auditory, visual, and somatosensory) evoked potential
patterns (MEPA- Mean Evoked Potential Abnormality) was 0.52 (p<.05)
