Brief Observation Schedule for Autism (BOSA)
Adaptable assessment of social communication challenges across age groups
The Brief Observation Schedule for Autism (BOSA) is a short, structured observation tool used to help identify signs of autism spectrum disorder (ASD). It provides a quick, focused way for professionals to observe social communication, interaction, and behaviors that may suggest autism.The BOSA is based on the well-known ADOS-2 (Autism Diagnostic Observation Schedule), but is designed to be shorter and easier to administer in a variety of settings—including clinics, schools, and even remotely.
Who Should Consider This Assessment?
The BOSA is ideal for:
- ⦿ Toddlers, children, teens, and adults with suspected autism
- ⦿ Parents or caregivers who have concerns about social or communication delays
- ⦿ Professionals who need a quick, structured observation as part of a larger autism evaluation
- ⦿ Situations where a full ADOS-2 cannot be completed due to time, access, or behavior concerns
How the Assessment Works
- ⦿ A psychologist observes the individual during a 10–20 minute interaction or play session
- ⦿ Different versions are used based on age and language ability (non-verbal to fully verbal)
- ⦿ Activities are designed to encourage natural social responses, such as eye contact, gestures, and conversation
- ⦿ The session can be done in person or via video, using standardized materials
- ⦿ After the observation, behaviors are scored using a checklist linked to autism symptoms
Why Choose the BOSA?
- ✔ Provides a quick, structured way to observe behaviors linked to autism
- ✔ Ideal for screening or supplementing a full autism evaluation
- ✔ Flexible and can be done in clinics, schools, or even at home with guidance
