We investigated the reliability and (convergent and discriminant) validity of an observational measure of physical aggression in toddlers and preschoolers, originally developed by Keenan and Shaw [1994]. The observation instrument is based on a developmental definition of aggression. Physical aggression was observed twice in a laboratory setting, the first time when children were 1-3 years old, and again 1 year later. Observed physical aggression was significantly related to concurrent mother-rated physical aggression for 2- to 4-year-olds, but not to maternal ratings of nonaggressive externalizing problems, indicating the measure's discriminant validity. However, we did not find significant 1-year stability of observed physical aggression in any of the age groups, whereas mother-rated physical aggression was significantly stable for all ages. The observational measure shows promise, but may have assessed state rather than trait aggression in our study.
我们调查了一种针对幼儿和学龄前儿童身体攻击行为的观察性测量方法的可靠性以及（聚合效度和区分效度），该方法最初由基南和肖[1994年]开发。该观察工具基于攻击行为的发展定义。在实验室环境中对身体攻击行为进行了两次观察，第一次是在儿童1至3岁时，一年后再次观察。观察到的身体攻击行为与2至4岁儿童母亲同时评定的身体攻击行为显著相关，但与母亲对非攻击性外化问题的评定无关，这表明了该测量方法的区分效度。然而，我们没有发现在任何年龄组中观察到的身体攻击行为有显著的一年稳定性，而母亲评定的身体攻击行为在所有年龄段都显著稳定。该观察性测量方法显示出了前景，但在我们的研究中可能评估的是状态性攻击行为而非特质性攻击行为。
