Summary
This study validated the Physical Self-efficacy Scale in a Black sample, confirming its structure but noting some item differences. Further research is needed to explore these variations.
Area of Science:
- Psychology
- Sociology
- Health and Human Performance
Background:
- The Physical Self-efficacy Scale is a key tool for assessing confidence in physical abilities.
- Previous validation was conducted on a White sample, raising questions about generalizability.
Purpose of the Study:
- To validate the Physical Self-efficacy Scale in an all-Black sample.
- To compare the scale's factor structure across different racial groups.
Main Methods:
- Principal components analysis was used to analyze the intercorrelation matrix of the Physical Self-efficacy Scale.
- The study involved a sample of 320 Black participants.
Main Results:
- The analysis largely confirmed the original validation study's findings.
- However, some items showed factor loadings on multiple factors, one item shifted subscales, and additional factors emerged.
Conclusions:
- The Physical Self-efficacy Scale appears generally valid for Black individuals.
- Differences observed warrant further investigation into racial or other influences on self-efficacy.
