Further validation of the Parent-Reported ADHD Symptom Infrequency Scale (PRASIS) in parents of children with oppositional defiant disorder and anxiety.

This study aimed to validate a novel parent-report measure of ADHD symptom inflation, the Parent-Reported ADHD Symptom Infrequency Scale (PRASIS), in a clinical sample. The PRASIS is composed of an Infrequency subscale and an ADHD subscale. Online participants were assigned to one of three groups: mothers of children with diagnosed ADHD ( = 110), mothers of children with diagnosed ODD and/or anxiety ( = 116), and mothers of children without ADHD, ODD, or anxiety.
