Research results on black-white differences in sense of personal control and research on the racial correlates of personal control are quite inconsistent. Using data from 36 black and 91 white North Carolina high school students, an attempt was made to validate both the sense of control construct and a racial separatism construct through Campbell and Fiske’s Multitrait-multimethod matrix. Surprisingly, the sense of control construct was validated for black students but not for white students, while the separatism construct was validated for white students but not for black students. The black students, however, scored more externally on the sense of control measures than did the white students, and externality for black students on the measures was related to support of racial separatism.
