The standardised Malay version of purdue pegboard test: Content validity and test-retest reliability testing

Area of Science:

• Occupational therapy
• Rehabilitation medicine
• Psychometrics

Background:

• The Purdue Pegboard Test (PPT) is a standard tool for assessing hand dexterity.
• A Malay translation is needed for the large Malay-speaking population in Southeast Asia.
• This study addresses the need for a culturally adapted and validated PPT in Malay.

Purpose of the Study:

• To translate the Purdue Pegboard Test (PPT) into Malay, creating the PPT-M.
• To establish the content validity of the PPT-M.
• To determine the test-retest reliability of the PPT-M.

Main Methods:

• Forward and backward translation by English teachers.
• Content validity assessment by 10 occupational therapy experts.
• Test-retest reliability evaluation with 60 undergraduate students.

Main Results:

• PPT-M showed excellent content validity (Item-CVI 0.9-1.0, Scale-CVI/Avg 0.93-0.95).
• 3-trial administration yielded good test-retest reliability (ICCs 0.76-0.85).
• 1-trial administration showed poor reliability (ICCs 0.34-0.46), with practice effects noted.

Conclusions:

• The PPT-M is a potentially valuable instrument for evaluating hand dexterity in Malay speakers.
• A 3-trial administration is recommended for optimal reliability.
• The PPT-M supports clinical and research applications in Malay-speaking contexts.
