This paper presents the development of a new measure of locus of control for adults, the Internal Control Index. Analysis of a field test and a junior college administration indicated an estimated reliability of .84, the presence of a strong principal component, two replicable factors, and evidence for convergent validity.

The random response technique was compared to a direct questionnaire, administered to college students, to investigate whether or not the responses predicted the social desirability of the item. Results suggest support for the hypothesis. A 33-item version of the Marlowe-Crowne Social Desirability Scale which was used is included. (GDC)
