NAN - WMT with Kids22 Multiple Regression Results: IQ & Age Effects on WMT Effort Measures Independent effects for IQ and Age on mean T score for effort on IR & DR. Results replicated & of similar magnitude when analyzing other effort measures (i.e, MC, PA), as well as DFR.

NAN - WMT with Kids24 Association of Referral Question to Diagnosis As much as possible, categories for reason for referral were the same as those for primary diagnosis. This allowed for a measure of congruence between reason for referral and diagnosis. Overall congruence was greater for children than it was for adults. Congruence for Children = 58% Congruence for Adults = 44%
NAN - WMT with Kids25 Association of Referral Question to Diagnosis Incongruence between referral and diagnosis was significantly different for the ADHD and LD when children and adults were examined separately. ADHD - Only 27% of adults referred were diagnosed ADHD, whereas 67% of children were diagnosed. LD – Only 35% of adults referred were diagnosed LD, whereas 59% of children were diagnosed, primarily with dyslexia.

NAN - WMT with Kids28 Conclusions The WMT when used with children 12 y/o and under may need special cut scores for accurate detection of invalid performance. Age, Overall Cognitive ability (e.g., IQ), and pathology (e.g., ADHD). What corrections need to be made cant yet be determined from the available data Alternative tests may prove to be a better solution to SVT when examining kids (e.g., MSVT)
