DSM v ADOS

DSM-5-TR (latest version of DSM) and ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition)  are two distinct tools used in assessment and dx of autism.

DSM-5-TR 

• Diagnostic manual that outlines the criteria for diagnosing ASD, including the presence of social communication deficits and RRB. 
• Serves as a reference for clinicians and researchers in making diagnostic decisions and ensures consistency in the diagnosis of ASD.

ADOS-2 

•  standardized observational assessment tool designed to aid in the diagnosis of ASD. 
• Administered by a trained professional and involves direct interaction with the individual  
• consists of a series of activities and social scenarios that allow the examiner to observe and evaluate the individual's communication skills, social interaction, play, and RRB. 
• It helps in determining whether an individual meets the diagnostic criteria for ASD and provides information to inform intervention and treatment planning.

ADOS-2 can be utilized as part of the diagnostic process, providing valuable information to support the dx under DSM-5. Both tools are commonly used together to aid in the assessment and diagnosis of Autism Spectrum Disorder.
