O&M Outcome Measures: VROOM and OMO
I have developed two new outcome measures for use in the context of typical O&M assessments (combining interview and observed travel). Both are constructivist measures, designed to be scored in collaboration with the client and any other relevant stakeholders. This approach to personal outcome measurement produces stronger data than unsubstantiated objective or subjective measures. These measures are currently being tested with O&M clients.
The VROOM (vision-related outcomes in O&M) instrument is used to rate functional vision between 1-50. Zero represents no light perception, and 50 represents vision for driving.
The OMO (O&M outcomes) instrument is used to rate functional mobility between 1-50. Zero represents housebound and inert; 50 represents elite travel skills and a ‘can do’ attitude to mobility that connects the traveller into the wider community, both geographically and socially.
These measures both use ordinal scales with clearly defined performance indicators so that scoring is precise, context-specific and transparent. The resulting measurement data can be used to profile O&M clients, O&M cohorts, functional performance in different travel conditions (e.g., day and night), and change pre-post intervention (medical intervention or O&M training).
VROOM and OMO instruments will soon be ready for multi-centre trials by O&M specialists. If you would like to participate in testing these measures in the context of everyday O&M practice, contact Lil.
