Abstract

Development and Validation of “Perceived Balance Scale for Older Adults”
The purpose of the study was to development and validation of a Perceived Balance Scale for older adults. Two samples each consist of 300 subjects participated in the research. Data collected with Activities-specific Balance Confidence (ABC), Fall Self-Efficacy-International (FSE-I) form. The data were analyzed with exploratory factor analysis (EFA) and principal components with varimax rotation, confirmatory factor analysis (CFA) with structural equations modeling, Pearson correlation coefficient, and t-student test, and with SPSS-16 and LESREL softwares. Exploratory factor analysis resulted in extraction two factors “Simple Tasks” and “Hard Tasks”, explaining 76.92% and 5.66% of variances, respectively. Results of first rank of CFA indicated that measurement model of Perceived Balance Scale for Older Adults was relatively fit and all measures and parameters were significant. CFI, IFI, and TLI measures were above 0.95, indicating these measures were excellent. There were significant correlations between Perceived Balance Scale for Older Adults and ABC (r=0.91, P≤0.0001) and FES-I (r= -0.83, P≤0.0001), confirming convergent validity of the new scale. Results of t-student test indicated that perceived balance mean score of subjects without fall history in past year than with fall history counterparts was higher significantly. Interclass correlation coefficient confirmed test-retest reliability (P≤0.01). Internal consistency for total score with Cronbach,s Alpha was 0.88. These results confirm validity and reliability of “Perceived Balance Scale for Older Adults”.
