Lester2 reported that self-reported stress was greater for individuals who had an external locus of control. The present scudy sought to explore this relationship in more depth using Levenson's (1974) modified internal-external locus of control scale. A questionnaire was given anonymously to 42 investigatory and administrative state police officers at headquarters (M,,, = 39.7, SD = 6.6). Included in the questionnaire was Levenson's I-E scale which measured control by powerful others, self, and chance, and stress scales which measured life events, overload, self-confidence, and Type A behavior (Girdano & Everly, 1979). Of the four stress measures, only one (self-confidence) correlated significantly with scores on the I-E scale. Belief in control by powerful others was associated with low self-confidence (r = -0.40, one tailed .p = 0.004), as was belief in chance control (r = -0.26, p = 0.05) while belief in self-control was associated with high self-confidence (r = 0.47, p = 0.001). It appears that belief in an internal locus of control is related to only some aspects of subjectively perceived stress.
