退伍军人事务部（VA）使用神经行为症状量表（NSI）来衡量其综合创伤性脑损伤（TBI）评估中的脑震荡后症状。本研究考察了NSI的项目属性、内部一致性和外部有效性。数据来自联邦政府资助的一项关于退伍军人经历的研究。参与者包括500名伊拉克行动和持久自由行动的退伍军人，其中219人至少有一次创伤性脑损伤。数据收集于纽约北部的五个VA医疗中心和一个VA门诊诊所。测量方法包括神经心理访谈、NSI、Beck焦虑量表、Beck抑郁量表II和创伤后应激障碍量表军事版。NSI表现出较高的内部一致性（总α = 0.95;子量表α = 0.88 - 0.92）。基于Caplan等人的分量表总计因子分析与NSI总分呈高度相关（r = 0.88 ~ 0.93）。NSI分数区分退伍军人与TBI的历史，但强烈的影响与可能的创伤后应激障碍，抑郁症和广泛性焦虑症相关的方差。结果表明，NSI是一个可靠和有效的措施脑震荡后的症状。量表效度在TBI和非TBI分类的区分中是明显的。然而，量表域并不限于TBI，并且延伸到检测在退伍军人群体中流行的其他情感障碍的可能影响。
The Department of Veterans Affairs (VA) uses the Neurobehavioral Symptom Inventory (NSI) to measure post-concussive symptoms in its comprehensive traumatic brain injury (TBI) evaluation. This study examined the NSI's item properties, internal consistency, and external validity. Data were obtained from a federally funded study of the experiences of combat veterans. Participants included 500 Operations Iraqi and Enduring Freedom veterans, 219 of whom sustained at least one TBI. Data were collected at five VA medical centers and one VA outpatient clinic across upstate New York. Measures included neuropsychological interview, NSI, Beck Anxiety Inventory, Beck Depression Inventory-II, and Posttraumatic Stress Disorder Checklist-Military Version. The NSI demonstrated high internal consistency (total alpha = 0.95; subscale alpha = 0.88 to 0.92). Subscale totals based on Caplan et al.'s factor analysis correlated highly with the NSI total score (r = 0.88 to 0.93). NSI scores differentiated veterans with TBI history from those without but were strongly influenced by variance associated with probable posttraumatic stress disorder, depression, and generalized anxiety. Results suggest that the NSI is a reliable and valid measure of postconcussive symptoms. Scale validity is evident in the differentiation of TBI and non-TBI classifications. The scale domain is not limited to TBI, however, and extends to detection of probable effects of additional affective disorders prevalent in the veteran population.
