Abstract: | This study examined the relationship between locus of control and academic performance by evaluating the academic achievement of defensive externals, which has been considered a confounding factor in previous research. A further objective was an examination of the effect of two mediating variables in their relation to locus of control and academic performance. One hundred sixty college students were administered the Internal, Powerful Others, and Chance scales, the Fear of Negative Evaluation scale, and the Achievement via Independence/via Conformance scales. Obtained results demonstrated that internals were academically superior to both defensive and congruent externals. Defensive externals were shown to have higher grade point averages than congruent externals, and female defensive externals achieved greater academic success than their male counterparts. Further results suggested that the relationship between locus of control and academic performance may not be a direct one but may be modified by specific mediating variables. |
