Impact of extrinsic factors on fine motor performance of children attending day care

Abstract Objective: To assess the impact of extrinsic factors on fine motor performance of children aged 2-years old. Methods: 73 children attending public and 21 private day care centers were assessed. Day care environment was evaluated using the Infant/Toddler Environment Rating Scale-Revised Edition (ITERS-R), fine motor performance was assessed through the Bayley Scales of Infant and Toddler Development-III (BSITD-III), socioeconomic data, maternal education and time of start at the day care were collected through interviews. Spearman's correlation coefficient was calculated to assess the association between the studied variables. Results: The time at the day care was positively correlated with the children's performance in some fine motor tasks of the BSITD-III, showing that the activities developed in day care centers were important for the refinement of specific motor skills, while the overall fine motor performance by the scale was associated with maternal education and the ITERS-R scale sub-item “language and understanding”. Conclusions: Extrinsic factors such as higher maternal education and quality of day care centers are associated with fine motor performance in children attending day care.

摘要：

研究目标：评估外在因素对2岁儿童精细运动表现的影响。

研究方法：选取就读于公立日托中心的73名儿童与就读于私立日托中心的21名儿童作为研究对象。采用《婴儿/学步儿环境评定量表（修订版）》（Infant/Toddler Environment Rating Scale-Revised Edition，ITERS-R）评估日托环境质量，通过《贝利婴儿及幼儿发育量表第三版》（Bayley Scales of Infant and Toddler Development-III，BSITD-III）测评儿童精细运动表现；同时通过访谈收集社会经济状况、母亲受教育程度及儿童入托时长等数据。采用斯皮尔曼相关系数分析各研究变量间的关联。

研究结果：儿童入托时长与BSITD-III量表中部分精细运动任务的表现呈正相关，表明日托中心开展的活动对特定运动技能的精细化发展具有重要作用；而该量表测评的整体精细运动表现则与母亲受教育程度及ITERS-R量表子项"语言与理解"显著相关。

研究结论：母亲受教育程度更高、日托中心质量更优等外在因素，与就读日托中心儿童的精细运动表现存在显著关联。
