To investigate the frequency and pattern of a wide range of restricted and repetitive behaviors in the second year of life.
Parents of 139 15-month-old typically developing infants from a community sample completed the Repetitive Behavior Questionnaire-2, giving information on restricted and repetitive behaviors (e.g., stereotyped motor movements, sensory interests, routines and rituals, and preoccupations with restricted interests) seen in their children.
The Repetitive Behavior Questionnaire-2 was found to be a reliable measure of these behaviors at this age and revealed a high frequency of particular types of repetitive motor movements in 15 month olds.
These findings have implications for the early detection of disorders characterized by high levels of restricted and repetitive behaviors, such as autism spectrum disorder.
调查广泛受限和重复行为在生命第二年的出现频率和模式。
来自社区样本的 139 名 15 个月大的典型发育婴儿的父母完成了重复行为问卷-2，提供了他们孩子出现的受限和重复行为（例如刻板的运动动作、感官兴趣、常规和仪式以及对受限兴趣的专注）的信息。
发现重复行为问卷-2 在这个年龄是这些行为的可靠测量工具，并揭示了 15 个月大的婴儿中特定类型的重复运动动作的高频率。
这些发现对早期检测以受限和重复行为水平高为特征的障碍具有重要意义，例如自闭症谱系障碍。
