The CORE instrument is commonly used to measure psychomotor disturbance. We examined the factor structure of the CORE in 266 adults with an acute episode psychotic depression, a disorder with a high rate of psychomotor disturbance. Exploratory factor analysis identified a two-factor solution: Factor 1 corresponded to the CORE's retardation and non-interactiveness items and Factor 2 corresponded to its agitation items. Internal consistency was excellent for Factor 1 but questionable for Factor 2. These findings suggest that the CORE's retardation and non-interactiveness items should be combined in one subscale when assessing patients with an acute episode of psychotic depression.
CORE 量表常用于测量精神运动障碍。我们在 266 名急性精神病性抑郁症患者中检验了 CORE 的因子结构，这种疾病的精神运动障碍发生率较高。探索性因子分析确定了两因子解决方案：因子 1 对应 CORE 的迟滞和非互动项目，因子 2 对应其激动项目。因子 1 的内部一致性非常好，但因子 2 的则值得怀疑。这些发现表明，在评估急性精神病性抑郁症发作的患者时，CORE 的迟滞和非互动项目应合并为一个子量表。
