Further Normative and Correlational Data on the Internal-External (I-E) Control of Reinforcement Scale

Rotter's measure of Internal-External control (I-E) was administered to a large group of adult Ss in the course of a smoking control research program. The obtained scores were lower than reported norms for college students. While I-E was unrelated to years of education, there was a small (r = −.14) but significant tendency for older Ss to be more internally oriented. Although I-E was not related to outcome of smoking treatment, relationships with personality and attitudinal variables were generally congruent with theoretical expectations.
