Autism Spectrum Disorders (ASD) diagnosis in very young children may be delayed due to doubts about validity. In this study, 77 children received a diagnostic and developmental evaluation between 16 and 35 months and also between 42 and 82 months. Diagnoses based on clinical judgment, Childhood Autism Rating Scale, and the Autism Diagnostic Observation Schedule were stable over time. Diagnoses made using the Autism Diagnostic Interview were slightly less stable. According to clinical judgment, 15 children (19%) moved off the autism spectrum by the second evaluation; none moved onto the spectrum. Results indicate diagnostic stability at acceptable levels for diagnoses made at age 2. Movement off the spectrum may reflect true improvement based on maturation, intervention, or over-diagnosis at age 2.
由于对有效性存在疑虑,幼儿自闭症谱系障碍(ASD)的诊断可能会延迟。在本研究中,77名儿童在16至35个月以及42至82个月期间接受了诊断和发育评估。基于临床判断、儿童自闭症评定量表和自闭症诊断观察量表的诊断随时间推移较为稳定。使用自闭症诊断访谈做出的诊断稳定性稍差。根据临床判断,到第二次评估时,15名儿童(19%)不再属于自闭症谱系;没有人进入该谱系。结果表明,2岁时做出的诊断在可接受水平上具有诊断稳定性。脱离谱系可能反映了基于成熟、干预或2岁时过度诊断的真正改善。
