| Neuropsychological effort has been extensively studied in adults involved in litigation; however, less is known about effort when examining adolescents and young adults for standardized testing accommodations. This study's purpose was to establish a baserate of poor effort and discover the most appropriate effort measures for 16-28 year olds undergoing neuropsychological assessments. This study involved 37 outpatient participants who were administered the Test of Memory Malingering (TOMM), Dyslexia Assessment of Simulation or Honesty (DASH), Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV), Reliable Digit Span (RDS), Woodcock Johnson tests of Achievement and Cognitive Abilities-Fourth Edition (WJ-IV), and Nelson Deny Reading Test (NDRT). None of the participants failed the TOMM; however, TOMM scores were significantly related to performance on Full Scale IQ (p<0.05), Processing Speed Index (p<0.05), and Passage Comprehension (p<0.01). The RDS was significantly related to performance on Passage Comprehension (p<0.05) and the pass/fail classifications demonstrated small to medium effect sizes in relation to FSIQ, Passage Comprehension, Reading Rate, and Standard Time Comprehension. The DASH Feigning Index was not significantly related to any subtests/indices, but pass/fail classifications demonstrated small to medium effect sizes in relation to FSIQ, PSI, Passage Comprehension, and Reading Rate. The TOMM and DASH Feigning Index were significantly related (Pearson Correlation=-0.494), and neither were related to RDS performance. Results indicate the need for continued research in this area. |
