Development of a Projective Measure of Perceived Locus of Control

A procedure for evaluating the internal-external (I-E) control dimension from TAT narratives was developed. Internally and externally oriented Ss, as defined by scores on the forced choice I-E scale, differed significantly in the expected direction in TAT ratings of experienced control. Scores on the projective instrument correlated significantly with scores on the questionnaire, and with the former technique it was possible correctly to categorize 80% of Ss according to I-E scale scores. The newly devised instrument demonstrated adequate discriminant validity.
