Abstract

OBJECTIVE. The Purdue Pegboard test often is used in clinical settings to evaluate changes in clients’ fine motor dexterity. The purpose of this study was to determine the test–retest reliability and practice effects of the Purdue Pegboard for persons with multiple sclerosis. In addition, this study compared the reliability of one-trial administration to three-trial administration of the four subtests.

METHOD. Thirty-two volunteers from a midwestern community-based maintenance rehabilitation center for persons with multiple sclerosis participated in this study. The participants were administered the four subtests of the Purdue Pegboard, three trials in a row. A second administration was completed 1 week later. Data from 25 participants were analyzed using paired t tests, Pearson product-moment correlations, and intraclass correlation coefficients.

RESULTS. The test–retest reliability coefficients ranged from .85 to .90 for one-trial administration and from .92 to .96 for the sum of three trials. No significant practice effects existed except for the sum of three trials of both hands.

CONCLUSION. This study suggests that the one-trial administration of the Purdue Pegboard is a sufficiently reliable assessment to use with persons with multiple sclerosis. Findings further suggest that for a person with multiple sclerosis, any changes in Purdue Pegboard scores using one-trial administration may reflect actual change in that person’s dexterity, as no practice effect was demonstrated in this study.
