TI  - Development and validation of a video-animated tool for assessing mobility.

AB  - BACKGROUND: Existing self-report measures of mobility ignore important contextual 
      features of movement and require respondents to make complex judgments about 
      specific tasks. Thus, we describe the development and validation of a short form 
      (sf) video-animated tool for assessing mobility, the Mobility Assessment 
      Tool-MAT-sf. METHODS: This study involves cross-sectional and longitudinal 
      analyses examining the measurement properties of the MAT-sf. The MAT-sf consists 
      of 10 animated video clips that assess respondents' level of proficiency in 
      performing each task. The main outcome measures used for validation included the 
      Pepper Assessment Tool for Disability (PAT-D), the Short Physical Performance 
      Battery (SPPB), and 400-m walk test. RESULTS: Participants (n = 234), 166 women 
      and 68 men, had an average age of 81.9 years and a variety of comorbidities with 
      65.4% having high blood pressure. An average SPPB score of 8.6 (range 2-12) 
      suggests that the study sample had evidence of compromised physical function but 
      was quite heterogeneous. The MAT-sf had good content validity, excellent 
      test-retest reliability (r = .93), and criterion-related validity with the PAT-D. 
      Moreover, the MAT-sf added considerable variance to the prediction of both SPPB 
      scores and 400-m gait speed over and above the PAT-D mobility subscale. The 
      MAT-sf also discriminated between older adults who completed or failed the 400-m 
      walk test. CONCLUSION: The MAT-sf is an innovative psychometrically sound measure 
      of mobility. It has utility in epidemiological studies, translational science, 
      and clinical practice.
