Reliability and Validity of the UMove Mobility Screen

Background: The UMove Mobility Screen (UMove) was developed to help bedside nurses accurately assess patient's mobility. Objectives: The purpose of this study was to assess reliability and validity of the UMove. Methods: Interclass correlation coefficient (ICC) and alpha coefficient was completed to assess was based on internal consistency and inter-rater reliability. Construct validity was determined by ICC using two-way random model. Results: Among the 176 participants the mean age was 57 years (SD = 15), and 60% were men (N = 105). Internal consistency and inter-rater reliability were acceptable (alpha coefficient of .94 and an intraclass correlation of .98). There was evidence of construct validity with an intraclass correlation of .95 between the UMove and the standard therapists' evaluation of patient functional mobility. Conclusion: There was evidence for reliability and validity of UMove. Future work should focus on the effectiveness of UMove on clinical outcomes.
