Abstract
Abstract Objective Effort testing with children has started to gain traction in the literature. The following case presents data from several number recall tasks similar to the Wechsler Digit Span and may expand the opportunities for embedded performance validity tests (PVTs). Method For the purpose of psychoeducational testing, a comprehensive battery of standardized neuropsychological tests was administered, including visual and auditory attention, language, visual-motor and fine motor skills, visual and auditory processing, executive functioning, and academics. Results The child showed impaired performance on Number Recall from the Kaufman Assessment Battery for Children, 2nd Edition (KABC-II) and Memory for Digits on the Comprehensive Test of Phonological Processing, 2nd Edition (CTOPP-2) that met the Weschler Digit Span cutoff indicative of poor effort. Evidence of Ganser symptoms (e.g., nearly correct or approximate answers) was present on math calculation performance on the Woodcock Johnson Tests of Achievement, 4th Edition (WJTA-IV). Further, apparently deliberate markings of “X” solely on his incorrect responses on a dichotomous (yes/no) reading task also suggested deliberate feigning of low reading skills. Conclusions This case highlights the importance of effort testing in children, especially as poor effort was not apparent to the examiner, nor did there appear to be any obvious gain. Comparing data on tasks similar to already established PVTs may help expand opportunities to test effort systematically and frequently throughout a neuropsychological evaluation, and has implications for other professionals (e.g., School Psychologists, Speech Language Pathologists, etc.) who evaluate children.
