Siblings have been hypothesized to positively impact the motor performance of children by acting as examples and by providing a safe environment, but they may also negatively impact motor performance because they could compete for the parent's time and care. Therefore, this study investigates the relationship between several sibling characteristics and motor performance in 3- to 5-year-old children. The sample consisted of 205 3- to 5-year-old children (mean age 50.9 ± 10.0 months, 52.2% boys). The Movement Assessment Battery for Children-2 was used to measure motor performance. The sibling variable was operationalized as the number of siblings present, the age difference between a child and its siblings, and the birth order position of a child. The confounding variables that were taken into account were the age, sex, and behavioral problems of the child and maternal education level. None of the investigated sibling variables were related to the total motor performance of a child after controlling for possible confounding variables. The absence of any associations between the sibling variables and motor performance might be explained by the characteristics of the study sample, the possibility that there is no linear relationship, or the presence of still unknown moderating or mediating factors.
兄弟姐妹被认为可以通过榜样作用和提供安全的环境对儿童的运动表现产生积极影响，但他们也可能对运动表现产生负面影响，因为他们可能会争夺父母的时间和照顾。因此，本研究调查了 3 至 5 岁儿童的几个兄弟姐妹特征与运动表现之间的关系。样本由 205 名 3 至 5 岁儿童（平均年龄 50.9 ± 10.0 个月，52.2%为男孩）组成。使用儿童运动评估电池-2 来衡量运动表现。兄弟姐妹变量被操作化为现有兄弟姐妹的数量、孩子与其兄弟姐妹之间的年龄差异以及孩子的出生顺序位置。考虑到的混杂变量是孩子的年龄、性别和行为问题以及母亲的教育水平。在控制可能的混杂变量后，没有一个调查的兄弟姐妹变量与儿童的总运动表现相关。兄弟姐妹变量与运动表现之间缺乏任何关联可能是由于研究样本的特点、可能没有线性关系或存在尚未确定的调节或中介因素所解释的。
