摘要

Rates of failure on performance validity tests (PVTs) are concerningly high among adults seeking neuropsychological evaluations for attention-deficit/hyperactivity disorder (ADHD). However, research has yet to investigate the potential influence of comorbid internalizing psychopathology on PVT performance in this population. To address this gap, the present study aimed to investigate whether invalid test performance differed significantly across individuals diagnosed with ADHD, ADHD and a comorbid internalizing disorder, an internalizing disorder only, or no diagnosis. Participants (N = 710) were extracted from an archival clinical database of consecutive patients referred for neuropsychological evaluation of ADHD in an urban area. Study groups were (1) No Diagnosis Comparison, (2) ADHD-Only, (3) ADHD + Internalizing Psychopathology, and (4) Internalizing Psychopathology-Only. Invalid test performance was defined as a failure on two or more freestanding and/or embedded PVTs. Overall, 17.2% of all participants failed two or more PVTs. The base rate of invalidity among the No Diagnosis group (0%) was significantly lower than the other three study groups, which produced remarkably similar rates of performance invalidity (i.e., 15–18%). Given the comparable rates of performance invalidity across study groups with a final diagnosis, results confirm the continued utility of best practices in PVT administration in neuropsychological assessments of ADHD even when comorbid internalizing psychopathology is present.
