- Abstract
Background. Mobility disability scale (MDS) is a new generic scale developed to assess level of mobility disability in community dwelling individuals. This scale being new requires systematic evaluation of psychometric properties for its effective use in community. Objectives of the study. The objectives of the study were to determine the internal consistency and test-retest reliability of the MDS in community dwelling individuals Method. Fifty-two community dwelling patients with mobility disability were evaluated using MDS. Total and domain scores were analyzed for internal consistency using Cronbach's alpha. After one week, same patients were re-evaluated using MDS and Intra class correlation coefficient (ICC) was used to analyze the test retest reliability. Results. MDS showed very high Cronbach's alpha (0.981) for total and domain scores (0.82- 0.96). MDS also showed high ICC (0.995, CI 0.991 to 0.997) for total and domain scores (0.97 to 0.99). Conclusion. We conclude that MDS possesses excellent internal consistency and test retest reliability which implies that MDS could be used to screen and quantify the mobility disability in community dwelling individuals.
