Normative data for a six-trial administration of the Verbal Selective Reminding Test

Area of Science:

• Neuropsychology
• Cognitive Psychology
• Gerontology

Background:

• The Verbal Selective Reminding Test (VSRT) is a critical tool for assessing verbal memory.
• Existing VSRT norms are often based on different administration trial counts, limiting direct comparison.
• Accurate normative data is essential for interpreting individual memory performance in clinical and research settings.

Purpose of the Study:

• To establish normative data for a six-trial administration of Form I of the Verbal Selective Reminding Test (VSRT).
• To provide gender-corrected norms based on age- and education-matched analyses.
• To develop a method for utilizing existing 12-trial VSRT norms with data from a 6-trial administration.

Main Methods:

• Collected data from 267 neurologically normal adults aged 18-91.
• Administered Form I of the VSRT using a six-trial protocol.
• Performed age- and education-matched pair analyses on 82 males and 82 females to generate gender corrections.
• Grouped normative data into seven age cohorts (18-29, 30-39, 40-49, 50-59, 60-69, 70-79, 80-91).
• Developed a regression-based procedure to link 6-trial and 12-trial VSRT data.

Main Results:

• Normative data were established for a six-trial VSRT administration across a wide adult age range.
• Gender-specific corrections were derived, accounting for potential performance differences.
• A regression-based method was successfully developed to bridge data from 6- and 12-trial VSRT administrations.

Conclusions:

• The provided normative data enhance the utility of the six-trial VSRT for assessing verbal memory in adults.
• Gender corrections improve the accuracy of VSRT interpretation across diverse populations.
• The regression-based procedure offers flexibility in applying existing norms to shorter VSRT administrations.
