Study of the psychometric properties of the Work Disability Diagnostic Interview (WoDDi) used with workers having a musculoskeletal disorder or a common mental disorder


The Work Disability Diagnostic Interview (WoDDI) was developed to help practitioners systematically identify factors related to work disability by means of a structured interview. This unique tool was developed based on both the scientific literature and input from expert clinicians. It is available for two major health problems associated with work disability and prolonged work absence: musculoskeletal disorders (MSD) and common mental disorders (CMDs). It is one of few such tools available in French.

The project findings will be used first to test the tool’s properties They will also provide work rehabilitation clinicians with an approach allowing more effective intervention with workers returning to work, by facilitating a comprehensive evaluation of the causes of prolonged disability.

The more precise evaluation obtained with the WoDDI can be used to select and implement personalized intervention strategies that better meet the needs of each worker.

The researchers are also considering collaborating with the international scientific community to adapt the tool cross-culturally and study its psychometric properties in other sociocultural contexts.
