Abstract：
OBJECTIVE: In the context of developmental trajectories, the association between adaptive functioning and core autism symptomatology remains unclear. The current study examines the associations of adaptive behavior with autism symptom sub-domains and with different facets of symptom expression.
METHODS: Participants include 36 children with a recent diagnosis of autism (33 males; mean age = 56.4 months; SD = 9 months). Families were recruited in the context of the Pediatric Autism Research Cohort (PARC) project. Parents filled out questionnaires at two time points, six months apart, regarding their child\'s autism symptoms and adaptive functioning. The longitudinal relationship between adaptive functioning and autism symptoms was investigated using Mixed Linear Model analyses: one assessing the relationship between general symptom levels and adaptive functioning, and another examining the associations between symptom frequency and impact with adaptive functioning. We conducted Pearson correlation tests at both time points to assess the associations between symptom sub-domains and adaptive functioning.
RESULTS: Findings showed that higher autism symptoms associated with lower adaptive behavior skills, and that this association remained stable over time. Autism impact scores did not significantly relate to adaptive skills, as opposed to frequency scores. Associations between adaptive functioning and autism symptom sub-domains strengthened over time.
CONCLUSIONS: These findings suggest that adaptive functioning is associated with parent-report autism symptomatology, and that this association changes and, on average, becomes stronger over time. Findings may indicate that frequency and impact of symptoms have differential roles in the development of adaptive skills and are worthy of further exploration.

摘要：
目标：在发展轨迹的背景下，适应性功能与自闭症核心症状之间的关联尚不清楚.当前的研究检查了适应行为与自闭症症状子领域以及症状表达的不同方面的关联。
方法：参与者包括36名最近诊断为自闭症的儿童（33名男性；平均年龄=56.4个月；SD=9个月）。在儿童自闭症研究队列（PARC）项目的背景下招募了家庭。家长在两个时间点填写问卷，相隔六个月,关于他们孩子的自闭症症状和适应功能。使用混合线性模型分析研究了适应性功能与自闭症症状之间的纵向关系：一种评估一般症状水平与适应性功能之间的关系，另一个检查症状频率和适应性功能影响之间的关联。我们在两个时间点进行了Pearson相关测试，以评估症状子领域和适应性功能之间的关联。
结果：研究结果表明，较高的自闭症症状与较低的适应行为技能有关，这种联系随着时间的推移保持稳定。自闭症影响得分与适应技能没有显著关系，而不是频率分数。适应性功能和自闭症症状子领域之间的关联随着时间的推移而加强。
结论：这些研究结果表明，适应性功能与父母报告的自闭症症状学有关，这种联系发生了变化，平均而言,随着时间的推移变得更强。研究结果可能表明，症状的频率和影响在适应技能的发展中具有不同的作用，值得进一步探索。
