Abstract:This study examined the reciprocal associations between sleep (duration and quality) and aggressive behavior in toddlers. The sample consisted of 82 children (43 boys and 39 girls) and their parents who completed two assessments, when children were 2 and 3 years old. At both time points, children wore an actigraph for 3 consecutive days to assess their sleep patterns, and both their parents reported on their child’s aggressive behavior. The results indicated negative associations between sleep quality at age 2 and both parents’ evaluations of aggressive behavior at age 3; in contrast, the relations between aggression at age 2 and sleep (duration or quality) at age 3 were small and nonsignificant. In line with studies of older children and adolescents, these results suggest that sleep difficulties are more likely to favor the emergence of aggressive behavior among young children than the converse.

幼儿的睡眠和攻击行为：调查协会的方向性

摘要：本研究调查了幼儿睡眠（持续时间和质量）与攻击行为之间的相互关系。样本由82名儿童（43名男孩和39名女孩）及其父母组成，他们分别在2岁和3岁时完成了两次评估。在这两个时间点，孩子都连续三天戴着活动记录仪评估他们的睡眠方式，并且父母双方都报告了孩子的攻击行为。结果表明，2岁时的睡眠质量与父母双方3岁时的攻击行为评估之间存在负相关关系。相比之下，2岁时的攻击性和3岁时的睡眠（持续时间或质量）之间的关系很小且不显着。根据对大龄儿童和青少年的研究，
