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

Area of Science:

• Neuropsychology
• Pediatric Psychology
• Clinical Psychology

Background:

• Performance validity tests (PVTs) are crucial for identifying non-credible symptom reporting in pediatric assessments.
• The Memory Validity Profile (MVP) is a commonly used PVT in pediatric clinical settings.
• Demographic factors may influence performance on PVTs, necessitating an examination of their impact on MVP scores.

Purpose of the Study:

• To investigate the influence of demographic variables on pass/failure rates of the Memory Validity Profile (MVP) in a mixed pediatric clinical sample.
• To determine if factors such as age, sex, race, or special education history affect MVP performance.
• To evaluate the appropriateness of a uniform cutoff score for the MVP across diverse pediatric populations.

Main Methods:

• A mixed clinical sample of 393 children was assessed using the Memory Validity Profile (MVP).
• Demographic data including age, sex, race, parental education, and special education history were collected.
• Statistical analyses were performed to compare demographic characteristics between children who passed and failed the MVP using a uniform cutoff (≤30/32 correct).

Main Results:

• 18% (n=72) of children failed the MVP.
• Children who failed the MVP were younger and more likely to have a special education history compared to those who passed (n=321).
• No significant differences were found based on sex, race, parental education, or history of ADHD/psychiatric treatment. False positives were more common in children under 10 and those with specific special education qualifications.

Conclusions:

• A uniform cutoff for the MVP is not advisable for all pediatric patients.
• Age and special education history are significant factors influencing MVP pass/failure rates.
• Development of adjusted MVP cutoffs is recommended to maintain 90% specificity across different ages and conditions.
