ABSTRACT

Although autism spectrum disorder (ASD) is a heterogeneous disorder, recently more homogeneous phenotypic subgroups, which still lack evidence, have been identified. Our goal is to describe and analyse different behavioural profiles of ASD, in social communication and interaction (SCI) and restricted and repetitive behaviours and interests (RRBIs), based both in behaviour type and frequency. The ASD typical behaviours were analysed based on Diagnostic Statistical Manual (DSM-5)’ criteria diagnosis. The sample comprised 75 children, aged between 8 and 12 years old (M = 9.67; SD = 1.29), through the application of the ASD Typical Behaviours Questionnaire (ASD-TBQ) and two group were identified. These groups differed in both ASD diagnostic domains as well as in their subdomains and most of behaviours. Group 1 presented a lower frequency of behaviours, being higher in SCI, while Group 2 presented a similar frequency in both domains. This research suggests that this identification is essential for understanding strengths and weaknesses, in order to establish targets of intervention, priorities and implement specific strategies.

摘要

尽管自闭症谱系障碍 (ASD) 是一种异质性疾病，但最近已经确定了仍然缺乏证据的更同质的表型亚群。我们的目标是根据行为类型和频率，描述和分析 ASD 在社会交流和互动 (SCI) 以及受限和重复行为和兴趣 (RRBI) 方面的不同行为特征。根据诊断统计手册（DSM-5）的诊断标准分析ASD典型行为。样本包括 75 名儿童，年龄在 8 至 12 岁之间（M = 9.67；SD = 1.29），通过应用 ASD 典型行为问卷 (ASD-TBQ) 并确定两组。这些群体在 ASD 诊断领域以及它们的子领域和大部分行为方面都不同。第 1 组表现出较低的行为频率，在 SCI 中更高，而第 2 组在两个领域中呈现相似的频率。这项研究表明，这种识别对于理解优势和劣势至关重要，以便确定干预目标、优先事项和实施具体战略。
