| dcterms.abstract | The purpose of this study is to gather evidence on the construct validity of Elderly Mobility Scale (EMS) by exploring its structural, substantive and discriminative components in assessing mobility level of institutionalized elderly residents. Inter-rater reliability of the EMS was established by having 5 trained raters rating the videotaped performance of 7 elderly residents. In addition, a total of 30 elderly residents were selected from the three institutional placements. Test-retest reliability was estimated by administering the EMS twice to all the selected elderly residents. A total of 90 residents were randomly selected from home for the aged, care and attention home and infirmary. EMS was administered to all residents following standardized testing protocols. The factor structure of EMS was examined by exploratory factor analysis. Item analysis was used to evaluate the items of the EMS in related to the mobility construct and discriminant analysis was used to predict group memberships in institutional placements. Inter-rater reliability was high (ICC(2,1) ranged from 0.95-1.00) for all items. ICC for the two subscales in test-retest reliability were 0.95 and 0.98. Two latent factors were extracted from the seven items of the EMS which suggested a two-subscale structure: bed mobility and functional mobility. Item-scale correlations for the two subscales were high, ranging from 0.95 to 0.96 and 0.85 to 0.94 respectively. High subscale internal consistency was demonstrated with high Cronbach's alphas (0.89 for bed mobility and 0.93 for functional mobility). The two subscales were found to predict 90% of the memberships among the three institutional placements. Factors contributing to the high inter-rater and test-retest reliability obtained in this study were explained. The importance of addressing the 2-factor structure of EMS was explored and the relationship between the two proposed subscales was discussed. Add-in new items and modification of present items in EMS were suggested to improve its clinical usage in deciding an appropriate institutional placement. Based on the present findings, EMS is concluded as valid and reliable in assessing mobility functions of institutionalized elderly residents. | en_US |
