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.

Validation of an adult ADHD measure of feigning in a sample including individuals with depression and anxiety symptoms.

Few studies of measures or techniques designed to detect feigning of Attention-Deficit/Hyperactivity Disorder (ADHD) have included groups reporting symptoms of depression and anxiety. Based on the high rate of comorbidity between ADHD and mood disorders, inclusion of such groups is important to mimic clinical referral patterns. The current study evaluated the validity of the ADHD Symptom Infrequency Scale (ASIS), a measure designed to detect malingered symptoms of ADHD, in a four-known groups design that included a group consisting of subjects with symptoms of anxiety and depression.

The parent-reported ADHD symptom infrequency scale (PRASIS): a parent report measure of ADHD symptom exaggeration.

The present article outlines the development of the parent-reported ADHD symptom infrequency scale (PRASIS), a novel stand-alone questionnaire designed to discriminate between parents exaggerating ratings of ADHD symptoms of their child from parents more accurately reporting symptoms. The PRASIS includes an Infrequency scale (INF) to measure infrequently reported symptoms of ADHD and a clinical scale to measure Diagnostic and Statistical Manual of Mental Disorders-5 Edition (DSM-5) defined ADHD symptoms (ADHD Total). An initial list of infrequency and clinical items was revised over the course of three studies, each conducted on a different sample of participants ( = 154,  = 203,  = 167) recruited via CloudResearch and consisting of mothers of children 4-12 years old.
