Figure 1:

Distribution of ADOS-2 Module 1 Items for Children with ASD Diagnosis. This is the frequency of scores for each module item. Note that the following items only had an option of 0,1, or 2: Intonation of vocalizations or verbalizations, Gestures, Showing, Spontaneous initiation of joint attention, and Facial expressions directed to others. Unusual eye contact can only score a 0 or 2. Since only three participants assessed with the Module 2 met criteria for ASD, only Module 1 is graphed.
