Overview of cognitive and behavioural measures

Symptom severity	Language	Motor	Visuospatial
Subdomains of ADI‐R + ADOS:
• Abnormal social behaviour (ADI‐A; ADOS‐B),	• Non‐word repetition task	• Purdue pegboard test	• Embedded figures test
• Abnormal communication (ADI‐B; ADOS‐A),	• F‐A‐S test
• Stereotyped, restricted behaviour (ADI‐C; ADOS‐D)

Functional measures of (a) symptom severity as measured by the ADI‐R and ADOS, (b) language as measured by the non‐word repetition task (phonological working memory), and F‐A‐S Test (verbal executive functioning), (c) motor skills as measured by the purdue pegboard test (motor dexterity), and (d) visuospatial abilities as measured by the embedded figures test.
