“…When using ASD-specific instruments such as the PDDBI to aid in diagnosis, sensitivity (agreement of the instrument with clinical diagnosis of ASD) and specificity (agreement of the instrument with clinical diagnosis of not ASD) are of importance. However, as noted previously (Cohen et al, 2016), these metrics depend, in part, on the degree to which the person being diagnosed displays behaviors that relate to ASD or to behaviors typical of disorders that can overlap with ASD, for example, social anxiety, obsessivecompulsive behaviors, language delay, and so on (Eaves, Wingert, Ho, & Mickelson, 2006;Havdahl, von Tetzchner, Huerta, Lord, & Bishop, 2016;Muratori et al, 2011).…”
