Within the context of a post-acute rehabilitation setting, association and agreement between results from the Neurobehavioural Cognitive Status Examination (NCSE) and from the neuropsychological (NP) evaluation are examined. All participants (n = 48) had sustained a severe traumatic brain injury and NCSE testing preceded NP testing by an average of 1 month. A significant relationship and fair classification agreement (i.e. presence or absence of cognitive impairment) was found between the overall results from NCSE and NP evaluation. Significant relationships were also observed between most NCSE subtests and paired NP tests thought to be assessing the same cognitive domains. However, the classification agreement (i.e. the presence or absence of deficient performance) between most NCSE subtests and paired NP tests was poor. The findings are discussed from the standpoint of individual treatment planning.
