Abstract: Background:Instruments for assessment of outcomes of mobility device interventions in terms of participation in everyday life and society for persons with walking disability are lacking. Objective:To describe the development process of the ‘Nordic mobility-related participation outcome evaluation of assistive device interventions’ (NOMO 1.0). Methods:1) Rasch analysis of a mobility-related participation questionnaire based on data from interviews with 111 powered wheelchair or scooter users. 2) Construction of a new self-report instrument, based on the ICF framework in a Nordic context. The development encompassed consultancy with mobility device users (N=41), assistive technology professionals (N=20) and researchers (N=17), and three rounds of pilot testing among mobility device users (N=113). 3) Reliability testing of the instrument among 147 mobility device users. Results:The Rasch analysis demonstrated construct validity, but low discriminative ability. The subsequently developed instrument was found to be content valid and feasible, and the test-retest reliability was satisfactory. Conclusions:The NOMO 1.0 is available free of charge in four Nordic languages. Further psychometric testing of the NOMO 1.0 is being planned.
