Abstract:
Background: The Sherer general self-efficacy scale (SGSES) is used to evaluate individuals’ levels
of self-efficacy. With poor low productivity levels among Zambian organisations there is a great
need of assessing employee’s self-efficacy in that self-efficacy is a predictor of employee
performance (Bureau of African Affairs, 2012; Mills, 2010). However, the psychometric properties of
the SGSES have not been established on a Zambian sample. This study therefore aimed at
evaluating the reliability and construct validity of the SGSES among public service employees in
Zambia.
Methods: A survey research design using a quantitative research strategy was used to achieve the
research objectives. The factorial structure models underlying SGSES were investigated using item
analysis, exploratory factor analysis (EFA) as well as the confirmatory factor analysis (CFA) via
structural equation modelling.
Results: Statistical analyses provided acceptable fit of the measurement model with the empirical
data.
Conclusion: This study has demonstrated evidence of construct validity for the usage of the
SGSES in the Zambian context.
