BACKGROUND: Several Patient Reported Outcome Measurements (PROMs) can be used to quantify participation in rehabilitation patients, yet there is limited comparative research on their content and psychometric properties to make an informed decision between them. OBJECTIVE: To compare the content and several psychometric properties of the Restriction and Satisfaction subscales of the Utrecht Scale for Evaluation of Rehabilitation - Participation (USER-P) with the Patient-Reported Outcomes Measurement Information System Ability to Participate in Social Roles and Activities (PROMIS-APS) and Satisfaction with Social Roles and Activities (PROMIS-SPS) v2.0 8-item short forms. METHODS: = 563). Coverage of participation domains, distributions, inter-item correlations, internal consistency, construct validity, and discriminative validity were compared between the PROMs. CONCLUSIONS: The internal consistency, construct and discriminative validity were similar between the USER-P subscales and the PROMIS short forms. It appeared that the USER-P offers more broad information about participation on item level and the total scores of PROMIS short forms offer more precise general information regarding participation.
