Embedded performance validity tests (PVTs), like Digit Span PVTs from Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV), offer a valuable means of evaluating validity without extending administration time. This study investigated the utility of novel indices of performance inconsistency for WAIS-IV Digit Span (DS IRs) in the detection of…

Students with Attention-Deficit/Hyperactivity Disorder (ADHD) are struggling writers. Yet no comprehensive model has been validated to explain their poor writing outcomes. This study aims to test whether an extended version of the Not-So-Simple View of Writing (NSVW) model can describe the effects of key abilities on writing performance in…

This study investigated the utility of four WAIS-IV Digit Span (DS) indices (traditional Reliable Digit Span [RDS], RDS-Working Memory [RDS-WM], RDS-Revised [RDS-R], and DS Age-Corrected Scaled Score [ACSS]) as embedded performance validity tests (PVTs) among a sample of 342 consecutive adults referred for neuropsychological evaluation of ADHD.…

The Adult ADHD Self-Report Scale screener is commonly used to determine if further evaluation of ADHD is required. However, despite use in college settings, the ASRS was not developed for this population, and limited relevant psychometric data exist. In this study, 190 college students completed the ASRS screener as well as a lengthier measure of…

Measurement invariance of the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V) 10 subtest primary battery was evaluated across sex, age (6-8, 9-11, 12-14, and 15-16 year-olds), and three diagnostic (attention-deficit/hyperactivity disorder, anxiety, and encephalopathy) groups within a large clinical sample (N = 5359) referred to a…

An attention-deficit/hyperactivity disorder (ADHD) diagnosis requires symptoms to be present across two or more settings, thus requiring information from multiple informants. Research consistently shows low to moderate agreement between parents and teachers; however, the mechanisms underlying these discrepancies remain unclear. This study examined…

Students with attention-deficit/hyperactivity disorder (ADHD) are frequently provided a separate room in which to take exams, to reduce external distractions. However, little research has explored the efficacy of this accommodation. In the present study, college students with (n = 27) and without (n = 42) ADHD diagnoses were administered two…

Malingering is a significant assessment concern in adults undergoing evaluations for attention deficit/hyperactivity disorder (ADHD) and may occur for a number of reasons, including access to medication and/or accommodations. Therefore, it is important to investigate ways to determine accuracy of self-reported ADHD symptoms. The present study used…

To examine reliability, validity, factor structure, and measurement invariance (i.e., configural, metric, and scalar invariance) of the Japanese Conners' Adult attention deficit hyperactivity disorder (ADHD) Rating Scales (CAARS), Japanese nonclinical adults (N = 786) completed the CAARS Self-Report (CAARS-S). Each participant was also rated by…

The evidence-based assessment of attention-deficit/hyperactivity disorder (ADHD) depends on adherence to "Diagnostic and Statistical Manual of Mental Disorders" (5th ed.; "DSM-5") diagnostic criteria and reliance on multi-method/multi-informant data. Although nearly all psychologists endorse these practices, college students…

This study investigated the extent to which standardized reading performance, individual perceptions of reading and test taking skills, and test anxiety predict the amount of extended time needed to equalize test access for college students with disabilities. Thirty-seven college students with a specific learning disorder (LD) and/or an attention…

The reliance on self-reports in detecting noncredible symptom report of attention-deficit/hyperactivity disorder in adulthood (aADHD) has been questioned due to findings showing that symptoms can easily be feigned on self-report scales. In response, Suhr and colleagues developed an infrequency index for the Conners' Adult ADHD Rating Scale (CII)…

The "Attention-Deficit/Hyperactivity Disorder Test-Second Edition" (ADHDT-2) is published through Pro-Ed in Austin, Texas. It was formally published in 2014, following critical revisions of the ADHDT, the reportedly popular initial version of this test that was published in 1995. The ADHDT-2 purports to act as a screener for individuals…

A large body of research has documented the relationship between attention-deficit hyperactivity disorder (ADHD) and reading difficulties in children; however, there have been no studies to date that have examined errors made by students with ADHD and reading difficulties. The present study sought to determine whether the kinds of achievement…

The diagnosis of attention deficit hyperactivity disorder (ADHD) distinguishes two dimensions of symptoms, inattention and hyperactivity-impulsivity for ages 3 to adulthood. Currently, no separate classification for preschool-age children exists, whereas preliminary research suggests that the two-factor structure of ADHD may not match the…
