Objectives: We tried to assess the stability of clinical diagnosis of ASD in Taiwanese toddlers when followed up 18- 21 months later.
Methods: We recruited 31 children aged between 24-36 months (male: female= 23: 8, with mean age=29.4 months, and mean mental age=17.5 months) from the Developmental Assessment Clinic of the
Results: At time 1, according to the initial diagnosis, those children were divided into autism group (N=12), PDDNOS group (N=6), and developmental delayed group (N=13). At time 2, for the autism group, nine children still had the diagnosis of autism, and one PDDNOS and two delayed; for PDDNOS group, one child had had changed diagnosis of autism, four still PDDNOS and one delayed; and for delayed group, none had autism, two children PDDNOS and 11 still delayed.
Conclusions: Our findings confirmed the possibility of early diagnosis of autism in children younger than 3 years old. And at our follow up study, the clinical diagnosis of either ASD or delayed group was quite stable. Further studies with larger sample size are needed.
