Summary
This study evaluated the Life Satisfaction Index--Well-being for older British adults. While showing acceptable reliability, the eight-item scale may need adjustments for this population.
Area of Science:
- Gerontology
- Psychometrics
- Health Psychology
Background:
- Assessing life satisfaction is crucial for the well-being of aging populations.
- Existing scales require validation in diverse demographic groups.
- The Life Satisfaction Index--Well-being is a tool used to measure subjective happiness.
Purpose of the Study:
- To examine the internal consistency and factorial composition of the eight-item Life Satisfaction Index--Well-being.
- To validate the adapted scale in a sample of elderly British individuals.
Main Methods:
- Cross-validation using a randomly drawn community sample.
- Sample comprised 155 rural individuals aged 65-89 years.
- Statistical analysis of internal reliability and factorial structure.
Main Results:
- The eight-item Life Satisfaction Index--Well-being demonstrated acceptable internal reliability.
- Factorial composition analysis indicated potential areas for modification.
- The scale's suitability for the elderly British sample was partially supported.
Conclusions:
- The Life Satisfaction Index--Well-being shows promise for assessing life satisfaction in older British adults.
- Further refinement of the scale may enhance its validity and reliability for this demographic.
- Continued psychometric evaluation is recommended for aging population research.
