There are few well-validated tools that focus on the assessment of walking
confidence in older adults.
The main objective of this study was to assess
construct validity of the 10-item Modified Gait Efficacy Scale (mGES) as a
measure of walking confidence in older adults. Twenty-four older females
completed the mGES, the 16-item Activities-specific Balance Confidence (ABC-16)
scale, and the Senior Fitness Test (SFT). Construct validity of the mGES was
evaluated by quantifying relationships between the mGES and the ABC-16 and the
SFT, and by examining the ability of the mGES to discriminate between known
groups (no/lower fear of falling versus higher fear of falling). There was a
strong correlation between mGES and the ABC-16 scale (rs = 0.85; p < 0.001). The
mGES was significantly associated with SFT components that required lower
extremity strength, stepping aerobic endurance, and walking agility and dynamic
balance (rs = 0.45 to 0.61; p < 0.05). Relationships between the mGES and number
of arm curls in 30 s, chair sit and reach test, and back scratch test were weak
(rs = 0.13-0.25; p > 0.05). Mean mGES score was 91.5% in a no/lower fear of
falling group, while it was 81.4% in a higher fear group (p = 0.22). There was a
trend toward a significant difference in the unstandardized residuals derived
from regression of ranked mGES scores on ranked covariate (age and 8 foot up and
go) scores, between the no/lower versus higher fear of falling group (p = 0.095).
These results support construct validity of the mGES as a measure of gait self-efficacy in community-dwelling older females.
