Summary
Physical self-efficacy, a measure of fitness confidence, was validated in Black undergraduates. Grip strength and flexibility significantly predicted physical self-efficacy, offering insights for health educators.
Area of Science:
- Exercise Science
- Psychology
- Health Education
Background:
- Physical self-efficacy is crucial for health behaviors.
- Understanding its predictors in diverse populations is important.
Purpose of the Study:
- To examine the construct validity of the Physical Self-efficacy Scale.
- To identify physical predictors of self-efficacy in Black undergraduates.
Main Methods:
- Factor analysis of the Physical Self-efficacy Scale.
- Assessment of cardiorespiratory function, flexibility, muscle strength, and endurance.
- Multiple regression analysis to identify predictors of physical self-efficacy.
Main Results:
- Factor analysis supported the Physical Self-efficacy Scale's construct validity.
- Nondominant hand-grip strength and sit-and-reach flexibility were significant predictors.
- Physical fitness components contribute to perceived physical capabilities.
Conclusions:
- The Physical Self-efficacy Scale is a valid measure for this population.
- Health educators can leverage physical performance data to enhance self-efficacy.
- Targeted interventions can improve both fitness and confidence.
