Some research findings have suggested that group day-care may be associated with an increased risk for physical aggression.
Cross-sectional maternal questionnaire data from a representative sample of 3431 Canadian 2- to 3-year-olds were used to compare rates of physical aggression shown by children looked after by their own mothers and those attending group day-care. A family risk index (using occupational level, maternal education, size of sibship, and family functioning) was created to test whether any difference in physical aggression might reflect social selection rather than social causation.
Aggression was significantly more common in children looked after by their own mothers than in those attending group day-care. Strong social selection associated with family risk was found, not only in the sample as a whole, but even within the high-risk subsample. However, after taking social selection into account, physical aggression was significantly more common in children from high-risk families looked after by their own parents. No such difference was evident in the majority (84%) of children from low-risk families.
Insofar as there are any risks for physical aggression associated with homecare they apply only to high-risk families.
一些研究结果表明，集体日托可能与身体攻击行为风险增加有关。
使用来自3431名加拿大2至3岁儿童的代表性样本的横断面母亲问卷调查数据，比较由自己母亲照顾的儿童和参加集体日托的儿童表现出的身体攻击行为发生率。创建了一个家庭风险指数（使用职业水平、母亲教育程度、同胞数量和家庭功能），以测试身体攻击行为的任何差异是否可能反映社会选择而非社会因果关系。
由自己母亲照顾的儿童中，攻击行为比参加集体日托的儿童明显更常见。不仅在整个样本中，甚至在高风险子样本中，都发现了与家庭风险相关的强烈社会选择。然而，在考虑社会选择因素后，由自己父母照顾的高风险家庭儿童中，身体攻击行为明显更常见。在大多数（84%）低风险家庭儿童中，没有明显差异。
就家庭照料与身体攻击行为存在的任何风险而言，这些风险仅适用于高风险家庭。
