This study revised the Work Performance Rating Scale (WPRS) for sheltered workshop employees. The updated WPRS, informed by worker and practitioner input and the Minnesota Theory of Work Adjustment, effectively assesses job performance and employability.

Area of Science:

  • Vocational Rehabilitation
  • Psychometrics
  • Industrial-Organizational Psychology

Background:

  • The Work Performance Rating Scale (WPRS) requires revision to ensure its validity for assessing sheltered workshop workers.
  • Existing assessment tools may not fully capture the nuances of work performance in this population.

Purpose of the Study:

  • To revise the content of the Work Performance Rating Scale (WPRS) for enhanced validity in assessing sheltered workshop workers.
  • To ensure the WPRS aligns with service user perspectives and theoretical frameworks.

Main Methods:

  • A focus group of 11 sheltered workshop workers provided user perspectives.
  • A panel of 23 frontline practitioners reviewed the WPRS content.
  • A 14-item amended WPRS was developed incorporating user feedback and the Minnesota Theory of Work Adjustment (MTWA).

  • An expert panel of 12 professionals validated the content of the amended WPRS.

    • Main Results:

    • The amended 14-item WPRS incorporated feedback from service users and practitioners.
    • The expert panel confirmed the amended WPRS's content validity and relevance to job satisfactoriness.
    • The revised WPRS demonstrated suitability for assessing the work performance of sheltered workshop workers.

    Conclusions:

    • The revised WPRS, guided by the Minnesota Theory of Work Adjustment (MTWA), is a valid tool for assessing sheltered workshop worker performance.
    • The study supports the MTWA's utility in improving the content validity of work assessment instruments.
    • The findings indicate the revised WPRS can effectively evaluate the employability of sheltered workshop workers.
