Development of a contextually appropriate, reliable and valid basic Wheelchair Service Provision Test.

Purpose: Currently, there is no internationally accepted way to measure the competency of wheelchair service professionals. The International Society of Wheelchair Professionals aims to develop a Wheelchair Service Provision - Basic Test as a preliminary step towards establishing a certification process.

Method: A team of wheelchair service provision experts developed test questions and conducted alpha and beta testing in order to validate them. Low-performing test items were eliminated. A pilot test was then conducted, which focused on developing a pass score, determining language barriers and validating the test as a measure of competency.

Results: 90 participants completed one of three versions of the Wheelchair Service Provision - Basic Test. A pass score of 70% was established and 135 questions were accepted for the final test. Analysis of variance indicated there was a difference in scores based on language (p = 0.001), but not based on experience level. This result motivated translation in to the United Nations' official languages.

Conclusions: The results indicate that the Wheelchair Service Provision - Basic Test is a valid method for measuring basic competency of wheelchair professionals. Additionally, researchers recommend a skills assessment to help to ensure only qualified wheelchair professionals receive the certificate. Implications for Rehabilitation Identify key steps in contextually appropriate test development. Describe the components of a contextually appropriate, reliable, and valid test for basic wheelchair service provision. Identify methods used for contextually appropriate test validation.
