Consistent with theory, findings supported construct validity of the PROMIS tripartite structure of health composed of Physical, Mental, and Social Health. PROMIS measures appeared to tap domains of health consistent with what is accepted for SCI and TBI populations, although the measurement of Physical Function was not equivalent across groups. Findings support the utility of PROMIS broadly as well as the need for condition-optimized measurement.
