Discriminant evidence suggests that the measure is distinct from other constructs, implying that it is a valid construct. A low correlation between measures of autism and ADHD symptoms suggests that they are distinct constructs and supports the validity of the autism measure. Convergent evidence refers to the correlation between measures of the same construct, multimethod evidence refers to the use of multiple methods to assess the same construct, and differential evidence refers to the ability of the measure to discriminate between different groups. None of these apply in this scenario where the focus is on assessing the validity of the autism measure.
