OBJECTIVE: To compare the measurement properties of the de Morton Mobility Index
(DEMMI) and the Hierarchical Assessment of Balance and Mobility (HABAM) in an
older acute medical inpatient population. DESIGN: Cross-sectional. SUBJECTS:
Older acute medical inpatients. METHODS: The DEMMI, HABAM and further assessments
were performed after hospital admission. Construct validity was assessed by
testing 13 hypotheses on convergent and known-groups validity. Test-retest
reliability and minimal detectable change were estimated based on a re-assessment
of unchanged patients. Floor and ceiling effects were used to indicate adequacy
of scale width. RESULTS: For both the DEMMI and HABAM, 11 (85%) hypotheses
regarding construct validity were confirmed (n = 158). Both scales showed strong
correlations with other multi-component mobility scales (Spearman's rho
0.75-0.92). Neither floor nor ceiling effects were evident. The intraclass
correlation coefficient was 0.98 (95% confidence interval (95% CI) 0.96-0.99) for
the DEMMI and 0.99 (95% CI 0.99-0.99) for the HABAM, respectively (n = 30). The
minimal detectable change with 90% confidence was 6 points on the 100-point DEMMI
scale and 1 point on the 26-point HABAM scale. CONCLUSION: The DEMMI and the
HABAM appear to be suitable for measuring mobility in older acute medical
patients.
