Preschool boys identified by their parents and/or teachers as active, inattentive, and impulsive (N = 69) at age 4 were compared with boys without problems (N = 43) on observational measures of symptom-related behaviors, obtained across contexts (home, laboratory, and preschool). Problem boys differed from comparison boys on measures of activity/inattention, noncompliance, and impulsivity obtained in the 3 settings. At a 2-year follow-up, when they were 6 years old, problem boys continued to differ from comparison boys on laboratory measures of activity and impulsivity; there also was some stability in these symptomatic behaviors. Implications of these findings for the emergence and persistence of externalizing problems in preschool boys are addressed.
父母和/或教师认定在4岁时表现活跃、注意力不集中且冲动的学龄前男孩（N = 69），与无行为问题的男孩（N = 43）就跨情境（家庭、实验室和学前班）获得的症状相关行为观察指标进行了比较。问题男孩在这三种情境下获得的活动/注意力不集中、不顺从和冲动指标上与对照男孩存在差异。在2年随访时，当他们6岁时，问题男孩在实验室活动和冲动指标上继续与对照男孩存在差异；这些症状性行为也有一定的稳定性。本文探讨了这些发现对学龄前男孩外化问题的出现和持续存在的意义。
