Summary
This study examined the factor structure of the General Self-Efficacy Scale. Results supported a three-factor model, with a higher-order factor providing an even better fit for the data.
Area of Science:
- Psychology
- Psychometrics
Background:
- The General Self-Efficacy Scale by Sherer et al. (1982) is widely used.
- Assessing its factor structure is crucial for accurate measurement.
Purpose of the Study:
- To conduct a confirmatory factor analysis of the adapted General Self-Efficacy Scale.
- To determine if the scale's proposed three-factor structure is supported by empirical data.
Main Methods:
- Confirmatory factor analysis (CFA) was employed.
- The adapted General Self-Efficacy Scale was the instrument of focus.
Main Results:
- The proposed three-factor model generally fit the data.
- A hierarchical model with three correlated factors and a higher-order general self-efficacy factor demonstrated a superior fit.
Conclusions:
- The findings provide strong support for the multidimensional nature of general self-efficacy.
- A higher-order factor model offers a more refined understanding of the General Self-Efficacy Scale's structure.
