Locus of control differences among stress groups

To assess among 3 groups differing in stress significance of differences in their scores on locus of control scales (Internal, Powerful Others, and Chance), 2 groups of college undergraduates (123 and 160 subjects) were tested. In both samples analysis indicated significant differences among the 3 groups in scores on the Powerful Others and Chance (external) scales, with the severely stressed group scoring higher than the milder stress groups. No significant differences were found on the Internality scale.
