Construct validity of the questionnaire was tested with Cronbach's alpha. The test-retest reliability was calculated in a subsample of 31 after a 4-5 week period (33.4 ± 11 days). To test the validity three other mobility-related self-efficacy scales (Activities-Specific Balance Confidence, Falls Efficacy scale and the Stair Self-Efficacy questionnaire) as well as two performance-based measures (gait speed and the Four Square Step test) were used.RESULTS: Both the internal consistency (T1 = 0.934, T2 = 0.958) as well as the test-retest reliability (0.932) were acceptable. Correlations between the mGES-D and the rest of the German mobility-related self-efficacy scales were above 0.758 and the performance-based mobility measures above 0.316.CONCLUSION: The mGES-D is a reliable and valid measure of walking confidence among healthy, community-dwelling older adults. Further application and testing of the mGES-D in primary care and clinical studies are needed to consolidate the findings.",
