A large sample of 7-year-old children (n = 940) was rated by teachers using the Rutter Child Scale B, a 26-item questionnaire covering a variety of behavioural problems. A factor analysis of the data revealed three main factors of interest, identified as aggressiveness, hyperactivity and anxiety-fearfulness. Measures based upon these factors had a reasonably high level of reliability and were moderately stable over a 2-year interval. An analysis of the relationship between these three behavioural measures and some cognitive measures indicated that only hyperactivity was negatively associated with cognitive ability. However, both hyperactivity and aggressiveness were related to adversity in the child's family background. The findings suggest the usefulness of distinguishing between aggressive and hyperactive dimensions of behaviour.
教师们使用涵盖各种行为问题的26项问卷——《拉特儿童量表B》对一大群7岁儿童（n = 940）进行了评分。对数据的因子分析揭示了三个主要的相关因子，分别确定为攻击性、多动和焦虑恐惧。基于这些因子的测量具有相当高的可靠性水平，并且在两年的时间间隔内具有一定程度的稳定性。对这三种行为测量与一些认知测量之间关系的分析表明，只有多动与认知能力呈负相关。然而，多动和攻击性都与儿童家庭背景中的逆境有关。研究结果表明区分行为的攻击维度和多动维度是有用的。
