The Agitated Behavior Scale (ABS; Corrigan, 1989) is a 14-item scale developed to monitor agitation during the acute phase of recovery from acquired brain injury. While previous studies have supported the reliability, internal consistency, and concurrent validity of the ABS, the current study was designed to investigate its underlying factor structure, as well as to determine systematic effects of time-of-day on the occurrence of agitation. Subjects were 212 patients with traumatic or other recently acquired brain injury who exhibited agitation during their treatment on a specialized brain-injury unit of an acute rehabilitation hospital. Confirmatory factor analysis revealed that agitation is best represented by one general construct with three underlying factors: Aggression, Disinhibition, and Lability. Analysis of agitation by nursing shift in which ratings were made confirmed that overall level was lowest during the night shift; however, the relationship between time-of-day and underlying factors deviated from this pattern. Results are discussed in terms of the necessity for objective measurement, definition of the construct of agitation, and time-of-day issues in sampling agitated behavior.
激越行为量表（ABS；科里根，1989）是一个包含14个条目的量表，旨在监测脑损伤后天恢复急性期的激越情况。虽然先前的研究支持了ABS的信度、内部一致性和同时效度，但本研究旨在探究其潜在的因素结构，并确定一天中不同时段对激越发生的系统性影响。研究对象为212例创伤性或其他近期获得性脑损伤患者，他们在急性康复医院的专业脑损伤科室接受治疗期间表现出激越症状。验证性因素分析表明，激越最好由一个具有三个潜在因素的总体结构来表征：攻击性、去抑制和情绪不稳定。对进行评分的护理班次的激越情况分析证实，夜班期间的总体激越水平最低；然而，一天中的时段与潜在因素之间的关系偏离了这种模式。本文从客观测量的必要性、激越结构的定义以及激越行为抽样中的一天中时段问题等方面对结果进行了讨论。
