Evaluation of Autism Spectrum Disorder in Early Childhood According to the DSM-5 Diagnostic Criteria

Objective: The aim of this study is to investigate, the DSM5 criteria
of, Autism Spectrum Disorder (ASD) and Social Communication
Disorder (SCD) in young children previously diagnosed with Pervasive
Developmental Disorder (PDD) on the DSM-IV-TR, and to evaluate
the effects of the symptom severity, emotional-behavioral problems, and
age and gender differences on the diagnoses.
Method: The study included 80 children between the ages of 18-72
months, who were diagnosed with PDD on the DSM-IV-TR criteria.
The severity of autistic symptoms was measured by the Autism Behavior
Checklist (ABC) and the Childhood Autism Rating Scale (CARS). The
presence of behavioral and emotional problems were evaluated by the
Aberrant Behavior Checklist (AbBC).
Results: Among the patients previously diagnosed with PDD, 9
(11.8%) did not meet the DSM-5 ASD criteria; 6 (7.9%) met the SCD
criteria while 3 could not be assessed on the SCD criteria due to their
small age and therefore not included in either diagnostic classes. The
mean CARS, ABC and AbBC scores of the patients who met the ASD
criteria, as compared to those who did not, were significantly higher.
The two groups did not differ significantly with respect to the gender
distribution and mean age.
Conclusion: The patients who had more and severe autistic symptoms
had a higher likelihood of getting an ASD diagnosis based on the
DSM-5 criteria. The diagnosis of the patients with subthreshold ASD
symptoms may be missed on the basis of the new diagnostic criteria.
