During COVID-19 and the social distancing it is not appropriate to administer ADOS-2 via telehealth nor when the parties involved are wearing face masks or face shields. ADOS-2 scores are not valid then.
Thus the Brief Observation of Symptoms of Autism (BOSA) was developed by Lord and colleagues (2020) to fill the gap left by not being able to carry out a valid ADOS-2. The BOSA relies on ADOS-2 codes thus only trained ADOS-2 diagnosticians with sufficient training and experience using the ADOS-2 can administer the BOSA.
BOSA provides a context of activities that can be presented by e.g., a parent or therapist within 12-14-minutes. Diagnosticians familiar with the ADOS-2 can observe the BOSA live, through telehealth, or on recorded video and complete many of the ADOS-2 codes following the new developed scheme (Lord et al. 2020).
The publication presenting BOSA (also in Polish language) – is pending. Check here soon.
