Hopkins Verbal Learning Test - revised process variables as embedded measures of performance validity

Area of Science:

• Neuropsychology
• Cognitive Assessment
• Psychometrics

Background:

• Performance validity tests (PVTs) are crucial in neuropsychological evaluations to detect non-credible effort.
• Traditional PVTs may not always capture subtle indicators of invalid performance.
• The Hopkins Verbal Learning Test - Revised (HVLT-R) offers potential embedded measures for performance validity.

Purpose of the Study:

• To investigate the utility of HVLT-R process variables as embedded performance validity tests (PVTs).
• To develop and evaluate a composite score (PRO-7) from HVLT-R process variables for detecting invalid performance.
• To assess the relationship between HVLT-R process variables, cognitive ability, and established PVTs.

Main Methods:

• Archival data from 52 adults undergoing neuropsychological testing were analyzed.
• Performance validity was assessed using a combination of free-standing and embedded PVTs.
• Seven HVLT-R process variables were examined individually and as a composite (PRO-7).

Main Results:

• Individual HVLT-R process variables correctly classified 77-79% of the sample.
• The PRO-7 composite demonstrated superior classification accuracy (83-85%) compared to individual variables.
• PRO-7 was independent of cognitive ability but strongly correlated with other PVTs; male sex and lower education were associated with failing PRO-7.

Conclusions:

• HVLT-R process variables are significant predictors of invalid performance in neuropsychological assessments.
• The PRO-7 composite shows promise as an alternative to traditional PVTs.
• Further research with larger samples is needed to confirm the generalizability and utility of HVLT-R process variables as PVTs.
