Objective: To verify the reliability and validity of the Japanese version of the Self-Efficacy for Exercise Scale in the elderly (SEE).
Methods: Individuals aged ≥65, who availed health services, were included. The Japanese version of the scale underwent forward translation and backtranslation by two bilingual interpreters. The intraclass correlation coefficient and Bland–Altman analysis were carried out for retest reliability verification. Cronbach's alpha coefficient was used to ensure internal consistency verification. A correlation analysis with the SEE was carried out for simultaneous validity verification, and an exploratory and confirmatory factor analysis was carried out for factor structure and model verification.
Results: Out of 294 participants, 217 participants aged 65 years and older were included in the analysis. The intraclass correlation coefficient was 0.57 for retest reliability and alpha coefficient was 0.95 for internal consistency. A correlation coefficient 0.42 was obtained with the SEE. Significant correlations were observed with motor behavior change stage, and maximum walking speed. Factor loadings of the three factors, namely, environmental load, physical load, and mental load, were above 0.5, and the contribution rate was 62.3%.
Conclusion: Construct validity was confirmed, and model goodness of fit by confirmatory factor-analysis was high, except for the root mean square error of approximation. Validation of reassessment reliability was shown as a challenge.
