The aim of this study was to investigate the constructs of
mobility-related participation and user satisfaction, two important outcome
dimensions within praxis and research on mobility device interventions. METHOD:
To fulfill this aim, validity and reliability of a 12-item scale on
mobility-related participation and a 10-item scale on user satisfaction were
examined in the context of older people's powered wheelchair use (n = 111). Rasch
analysis and correlation analysis were applied. RESULTS: Construct validity of
both scales was confirmed. The reliability of the user satisfaction scale was
good, while the mobility-related participation scale was not optimal in
discriminating between persons with a high degree of mobility-related
participation. It was demonstrated that mobility-related participation and user
satisfaction are separate, not related constructs. CONCLUSIONS: It can be
concluded that the investigated mobility-related participation and user
satisfaction constructs appear to be valid. Since the two constructs are not
related and both yield important information, both dimensions should be evaluated
in outcomes research and praxis targeting powered wheelchair interventions.
Reliability problems of the mobility-related participation scale indicate the
complexity of this construct.
The results have been instrumental in the development of a new scale for measuring mobility-related participation
'The NOMO 1.0'.
