It provides structured activities like free play and bubble play to evaluate social interaction and communication skills, aiding in accurate diagnosis and classification of autism severity levels.

1.1 Overview of ADOS-2

The Autism Diagnostic Observation Schedule, Second Edition (ADOS-2), is a comprehensive diagnostic tool for assessing Autism Spectrum Disorder (ASD). It is widely regarded as the gold standard for observational assessments, providing a structured framework to evaluate social interaction, communication, and repetitive behaviors. The ADOS-2 consists of four modules tailored to different age groups and language abilities, ensuring accurate assessment across various developmental levels. Professionals use standardized activities, such as free play, bubble play, and response to name, to observe and score behaviors. The tool is designed for clinicians, psychologists, and specialists to gather reliable data for diagnosis and classification of autism severity levels. Its structured format and standardized scoring system ensure consistency and reliability in assessments, making it an essential resource for ASD evaluation.

1.2 Purpose and Application

The primary purpose of the ADOS-2 is to assess and diagnose Autism Spectrum Disorder (ASD) through structured, observational activities. It is designed to evaluate social interaction, communication, and repetitive behaviors in individuals across various age groups and developmental levels. The tool is widely applied in clinical and research settings to inform diagnostic decisions and guide intervention strategies. Professionals, such as psychologists and clinicians, use the ADOS-2 to gather standardized data, ensuring reliable and consistent assessments. It is particularly valuable for early detection of ASD, as it provides insights into developmental delays and behavioral patterns. While not a stand-alone diagnostic tool, the ADOS-2 is often used alongside other assessments, like the Autism Diagnostic Interview, to form a comprehensive evaluation. Its application spans both clinical practice and research, making it an essential resource for understanding and addressing ASD.

Modules of ADOS-2

The ADOS-2 consists of four modules, each tailored to specific age groups and developmental levels, assessing social interaction, communication, and play skills through structured activities like free play.

2.1 Module 1: Toddler Assessment

Module 1 of the ADOS-2 is designed for toddlers aged 12-30 months, focusing on early developmental assessment.
