The Interdisciplinary Diagnostics of Autism Spectrum Disorder Using DC:0-5 ^TM: A Case Report

Abstract

BACKGROUND:

The Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood (DC:0-5 ^TM) is widely used in many Western countries. For Russian specialists, such classification represents a relatively new tool for the comprehensive diagnosis of mental disorders in children from birth to the five-year-old threshold. The purpose for presenting this case study report is to showcase the practical application of the DC:0-5 ^TM.

AIM:

This study aims to illustrate the diagnostic process according to the DC:0-5 ^TM criteria using the example of a specific clinical case report involving the collaborative efforts of two specialists: a child psychiatrist and a clinical child psychologist.

METHODS:

DC:0-5 ^TM consists of five axes. The main axis focuses on clinical diagnosis criteria for mental disorders, considering their age specificity. The remaining four axes allow one to take into account and specify data related to biological, social, and psychological factors, which play a crucial role in understanding the causes and characteristics of a mental disorder in a child.

RESULTS:

In the examined case, an analysis of symptoms by means of the Clinical Disorders axis revealed that they were consistent with the diagnostic criteria for autism spectrum disorder. The use of the remaining axes supplemented the clinical diagnosis with specific details about the adverse physical health factors in the child, a high cumulative stress burden, significant developmental delays in the emotional, speech, and social dimensions, as well as dysfunction in the mother-child dyad. Since the parents declined medication for their son, this information proved crucial in developing a support program for both the child and the family.

CONCLUSION:

The comprehensive diagnostic approach using the DC:0-5 ^TM axes proved highly effective, not only in psychiatric diagnosis but also in establishing goals and objectives for subsequent intervention. Its application in psychiatric, clinical psychology, and corrective educational practices has the potential to make support for children in their early years a more personalized and family-oriented undertaking.
