Summary
Most work-related assessments lack sufficient evidence of validity, impacting occupational rehabilitation. Clinicians must carefully evaluate assessment validity before use.
Area of Science:
- Occupational rehabilitation
- Psychometrics
- Evidence-based practice
Background:
- Work-related assessments are crucial in occupational rehabilitation.
- A significant concern is the insufficient evidence supporting the validity of these assessments.
- Despite ongoing development, a comprehensive review of validity evidence is lacking.
Purpose of the Study:
- To evaluate the extent and quality of evidence for the validity of work-related assessments.
- To determine the level of validity for assessments with sufficient supporting evidence.
Main Methods:
- A systematic review of available literature and sources was conducted.
- The study examined 28 distinct work-related assessments.
- The review focused on establishing the extent to which validity has been demonstrated for each assessment.
Main Results:
- The study presents the levels of evidence and validity for each of the 28 assessments.
- A majority of work-related assessments exhibit limited evidence of validity.
- Among assessments with adequate evidence, validity varied from poor to good, with no single instrument demonstrating moderate to good validity across all areas.
Conclusions:
- Clinicians can utilize this study's findings to critically assess the validity of chosen occupational rehabilitation assessments.
- The findings highlight a need for improved validity evidence in work-related assessment tools.
- Informed selection of assessments is essential for effective occupational rehabilitation outcomes.
