Comparability of Self-Ratings and Observer Ratings in Occupational Psychosocial Risk Assessments: Is There Agreement?

The reasonable agreement and excellent reliability in workers' self-ratings justify aggregation of item means at the group level. Furthermore, if the work activities are homogenous and the committee consists of members from different OSH specialties, observer ratings and self-ratings provide comparable results. According to this study's results, both methods are reliable assessment strategies in the context of psychosocial risk assessment. The observer rating approach is especially suitable for small-to-medium enterprises that do not have access to a large anonymous survey assessment.
