Abstract: The purpose of this study was to revise the content of the Work
Performance Rating Scale (WPRS) as a valid assessment tool for sheltered
workshop workers. A focus group of 11 sheltered workshop workers was recruited
to collect their opinions about the relevance of the WPRS from the service
users' perspectives. A panel of 23 frontline practitioners who had experience
in using various work assessment instruments provided at their work setting was
recruited to review the content of the WPRS. A 14-item amended version of the
WPRS with five new items added was proposed based on the opinions of service
users, frontline practitioners, and the concept of the Minnesota Theory of Work
Adjustment (MTWA). An expert panel of 12 professionals at the senior level from
various vocational rehabilitation settings was recruited to comment on the
content validity of the 14-item amended version of the WPRS. The expert panel
agreed that the amended version of the WPRS was related to the concept of job
satisfactoriness which could be used to assess the work performance of
sheltered workshop workers. Thus, the use of the MTWA for improving the content
validity of the WPRS to assess the employability of sheltered workshop workers
was supported by the findings of the study.
