Abstract Background The Work Support Profile (WSP) is a brief assessment instrument that enables staff supporting adults with disabilities to provide calibrated and individualized support for specific work tasks. This paper sought to examine the psychometric properties of WSP for people with disabilities. Method A pilot study was conducted with 239 sheltered workshop employees diagnosed mainly with intellectual disability to explore the structure of this assessment tool, and provide initial evidence of its psychometric properties. Subsequently, a larger‐scale study captured a nationwide profile of 761 sheltered workshop employees with intellectual disability. Results Across both studies, factor analyses yielded a conceptually acceptable 5‐factor structure with 33 items accounting for approximately 65% of the variance. Furthermore, the reliability, convergent and discriminant validity of WSP can be considered adequate. Conclusion Results provide preliminary evidence that WSP is a psychometrically adequate tool for assessing the work support needs of adults with disabilities on given work tasks.
