Summary
This study translated and validated exercise and functional activity scales for older Thai adults undergoing geriatric rehabilitation. The translated Self-Efficacy and Outcome Expectations Scales demonstrated good reliability for use in this population.
Area of Science:
- Geriatric Rehabilitation
- Health Psychology
- Instrument Translation and Validation
Background:
- Assessing self-efficacy and outcome expectations is crucial for exercise adherence in older adults.
- Existing scales need cultural adaptation and validation for diverse populations, such as older Thai adults.
Purpose of the Study:
- To translate the English Self-Efficacy and Outcome Expectations Scales for Exercise and Functional Activity into Thai.
- To establish the reliability and internal consistency of these translated scales in older Thai adults undergoing geriatric rehabilitation.
Main Methods:
- Correlational design with repeated measures.
- Translation and back-translation of the Self-Efficacy for Exercise Scale (SEES), Self-Efficacy for Functional Activity Scale (SEFAS), Outcome Expectations for Exercise Scale (OEES), and Outcome Expectations for Functional Activity Scale (OEFAS).
- Administration of scales to 20 older adults (≥60 years) post-orthopedic surgery on the 4th and 5th postoperative days.
Main Results:
- Sufficient internal consistency was found for all scales (alpha coefficients: SEES=0.84, SEFAS=0.86, OEES=0.70, OEFAS=0.86).
- Good test-retest reliability was demonstrated (Spearman's rho: SEES=0.84, SEFAS=0.87, OEES=0.61, OEFAS=0.54).
Conclusions:
- The translated Thai versions of the SEES, SEFAS, OEES, and OEFAS are reliable and suitable for use in older Thai adults in geriatric rehabilitation.
- These validated instruments can inform future research on exercise behavior and functional activity in this demographic.
- Findings support the cross-cultural adaptation and applicability of these scales for assessing older Thai adults' confidence and expectations regarding physical activity.
