Locus of control, consistency of vocational interest patterns, and academic achievement.

Administered the SVIB, the W. James I-E Scale, and the American College Testing Program Examination (ACT) to 356 male university freshmen. Ss were classified as internals or externals on locus of control and as consistents or inconsistents on vocational patterns based on J. Holland's classification schema for scales on the SVIB. ACT scores were used to control for ability. Internals had a significantly higher GPA than externals; consistents had a higher GPA than inconsistents, but no significant interaction effects between vocational interest patterns and locus of control were found.
