The purpose of this study was to explore preliminary external validation of a standardized music therapy assessment tool used in the detection of awareness with the DOC patient population with an external reference standard. Eight subjects were administered both the MATADOC and the CRS-R within five days of one another, and results were compared on the levels of overall diagnosis, analogous domain subscales, and intra-assessment relationships between individual domains and overall diagnosis. Results indicated a very strong level of agreement for overall diagnosis (rs = .85, p < .01), very strong relationships between the auditory and visual components of the two assessments (rs = .76, p < .05, and rs = .81, p < .05, respectively), and a strong, but non-significant relationship between arousal scores on the two assessments (rs = .68, p > .05). The MATADOC demonstrated very strong relationships between each of the auditory, visual, arousal, and verbal command domains to the overall diagnostic outcome. The CRS-R showed a very strong relationship between the auditory domain and the overall diagnostic outcome, and a strong relationship between the communication domain and the overall diagnostic outcome. All of the findings have positive implications for the use of MATADOC as a diagnostic measure or a companion assessment in questionable or borderline cases. Limitations include a small sample and a single MATADOC assessor who both administered and scored the MATADOC sessions.
