Pass/failure on the memory validity profile: one size does not fit all

This study sought to determine the influence of various demographic variables on pass/failure on a pediatric performance validity test, the Memory Validity Profile (MVP) in a mixed clinical sample (n = 393; 62% male, 62% White, median age 11 years). Children who failed the MVP (n = 72, 18%) according to a uniform cutoff of ≤30/32 correct were younger and were more likely to have a special education history than those who passed it (n = 321, 82%). There were no statistically significant group differences on other variables such as sex, race, parental education, history of treatment for ADHD or other psychiatric disorder. Possible false positive findings were relatively most common in children under the age of 10 years and in children who received special education services under the Physical/Other Health Impairment or Speech & Language Impairment qualifications. We conclude that a uniform cutoff for pass/failure on the MVP across any and all ages and diagnostic categories is ill-advised. Instead, we recommend the development of various adjusted cutoffs for this test that maintain 90% specificity at both ends of the age spectrum as well as with different medical or developmental conditions.
