Construct and predictive validity of a self-reported measure of preclinical mobility limitation.
OBJECTIVES To vali date self-reported pre clinical mobility limitation concept and self-report assessment method against muscle power and walking speed , and to study the predictive validity of pre clinical mobility limitation with respect to future risk of manifest mobility limitation . DESIGN Observational prospect i ve cohort study and cross-sectional analysis . SETTING Research laboratory and community . PARTICIPANTS A total of 632 community-living ( age range , 75 - 81 y ) women and men took part in the baseline assessment s and 302 persons in the semi-annual interviews on mobility limitation over 2 years . INTERVENTIONS Not applicable . MAIN OUTCOME MEASURES Walking speed , muscle power , and self-reported pre clinical and manifest mobility limitation . Pre clinical mobility limitation was defined as self-reported tiredness or modification of task performance without task difficulty . At baseline , 4 subgroups were created according to self-reported pre clinical mobility limitation in any of 3 mobility tasks ( walking 2 km , walking 0.5 km , climbing up stairs ) : no limitation , pre clinical limitation , and minor and major manifest limitation . RESULTS At baseline , participants with pre clinical mobility limitation showed intermediate levels of walking speed and muscle power , compared with those with no limitation or manifest mobility limitation . Participants reporting baseline pre clinical mobility limitation had 3- to 6-fold higher age- and sex-adjusted risk of progressing to major manifest mobility limitation during the 2-year follow-up compared with participants with no limitation at baseline , whereas the risk among those with minor limitation at baseline was 14- to 18-fold higher compared with those with no limitation . CONCLUSIONS The self-report assessment tool proved to be a valid measure to capture the early signs of disability and may serve as an inexpensive tool for identifying those nondisabled persons at high risk for future disability
