Hopelessness, internal-external locus of control, and depression.

This research examined the relationship between hopelessness, defined as a system of negative expectancies about the future, and two theoretically relevant constructs: internal-external locus of control, and depression. Two samples of 67 and 44 undergraduates were administered the Beck, et al. Hopelessness Scale, the Rotter Internal-External Scale, and the Beck Depression Inventory. The data of both samples supported the predictions that hopelessness would be positively related to external locus of control and to depression.

Internal-external locus of control and guilt.

This study examined the relationship between internal-external locus of control and guilt. Ss were 65 male and 137 college undergraduates who completed the Rotter I-E scale and the Mosher Hostility and Morality-Conscience Guilt Scales. Results demonstrated that internals reported a higher degree of hostility guilt than externals. Also, females expressed greater hostility and morality-conscience guilt than males.

Defensive externality and its relation to academic performance.

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.
