The Neurobehavioural Rating Scale (NRS) was developed to allow quantification of clinical observations of the behaviour of individuals following traumatic head injury. Initial validation of this instrument reported satisfactory interobserver reliability, as well as preliminary support for its validity in differentiating both severity and chronicity of head injury. In the present study, reliability and content validity of the NRS were replicated using a population of severe head injury patients undergoing inpatient rehabilitation. Concurrent, independent assessment using the NRS was conducted weekly by two members of an inpatient, traumatic head injury team. Acceptable levels of interobserver reliability were found, despite less control over observed behaviour in the naturalistic setting used. Content validity was also supported in this replication, although recommendations for 'tightening' the NRS included better definition of the seven-point severity rating for each item, as well as potential deletion of two items that contributed little to differential variance in the total NRS score. The NRS appears to be a promising clinical and research tool for assessing the neurobehavioural sequelae of traumatic head injury. Its strengths include efficiency of administration and the flexibility to administer through brief, structured interviews or observations in a naturalistic setting. Continued research on the NRS in different settings and with different populations is required to establish its validity.
神经行为评定量表（NRS）的开发是为了对创伤性脑损伤患者的行为进行临床观察量化。该工具的初步验证报告显示，观察者间信度令人满意，并且在区分脑损伤的严重程度和慢性程度方面的有效性也得到了初步支持。在本研究中，对一组接受住院康复治疗的重度脑损伤患者进行了NRS的信度和内容效度重复验证。住院创伤性脑损伤治疗团队的两名成员每周使用NRS进行同步、独立评估。尽管在自然环境中对观察行为的控制较少，但仍发现观察者间信度处于可接受水平。此次重复验证也支持了内容效度，不过对NRS“收紧”的建议包括对每个项目的七点严重程度评分进行更明确的定义，以及可能删除两个对NRS总分差异方差贡献不大的项目。NRS似乎是评估创伤性脑损伤神经行为后遗症的一种很有前景的临床和研究工具。其优点包括实施效率高，并且可以通过简短的结构化访谈或在自然环境中的观察灵活实施。需要在不同环境和不同人群中对NRS继续进行研究以确定其有效性。
