The purpose of this study was to develop, validate and conduct a feasibility study of three remote basic skills assessment modalities for wheelchair service providers (WSP) including an online mock-client case study quiz (m1), an in-person skills assessment (m2) and a video conference skills assessment (m3). Prior to this study, we were unaware of a validated remote basic skills assessment for WSP that reflects all WHO 8 wheelchair service provision steps. Such a test may be an asset to training or professional organizations like the International Society of Wheelchair Professionals (ISWP) as a way to test provider competency or to warrant certification. Currently, we are unaware of any certification that includes a skills test as a requirement.
Our first hypothesis was that all three modalities are comparable as evidenced by the mean score of ISWP Basic Knowledge Test (i.e., within one SD). Our second hypothesis was that all modalities were feasible according to seven defined feasibility criteria. Inclusion criteria included passing the ISWP Basic Knowledge Test. We recruited a total of 12 participants; all completed m1. Five completed m2 at the 35th International Seating Symposium and five completed m3 via Adobe Connect. Two participants dropped out of the study prior to completing a second testing modality.
The results show that our first hypothesis was rejected because only m1 mean score was comparable to the ISWP Basic Knowledge Test (SD = .44). This is in contrast with the Wilcoxon signed-rank test results that show a statistically significant difference between these two. Hypothesis two was not rejected. The feasibility results reveal that all three modalities met the minimum criteria (86% success). Thus, based on this finding, m1, 2 and 3 have the potential to serve as remote basic skills assessments through ISWP or other training or credentialing organizations. However, according to both test performance and feasibility criteria, the study team and participants encountered the fewest challenges with m2, and therefore, we believe this assessment has the highest potential to be included in the ISWP WSP basic skills certification process to ensure fidelity to practice.
