Coefficient alpha reliability estimates and interscale correlations were obtained for five locus of control scales administered to 267 undergraduates: the Rotter Internal-External Scale; the 18-item version of the Reid and Ware scale; the Levenson scale; the Nowicki-Strickland adult internal/external scale; and the Duttweiler Internal Control…

The results show that the stability of the Rotter Internal-External Locus of Control Scale is established over an eight month period. Concurrent validity of the Rotter Internal-External Locus of Control Scales in relation to the MacDonald-Tseng Locus of Control Scale is established. (Author/DEP)

Underlying constructs of the Nowicki-Strickland Locus of Control Scale for Children (NSLOCSC) were identified through factor analysis and cross-validated with two similar samples of high school students. The two resultant dimensions appeared to measure Social Control (six items) and Self Control (two items). (Author/GK)

This study examined selected pyschometric properties of the Health Locus of Control Scale (HLOC) (Wallston, Wallston, Kaplan, and Maides, 1976). Specifically, the HLOC factor structure, factor score reliabilities, and correlations with social desirability were investigated. (Author)

The factor structure of the Adult Norwicki-Strickland I-E Scale, sampling 174 college students, indicated differential factor dimensionality for males and females. The findings also support the contention that I-E is multidimensional in nature; however, these dimensions reflecting factorial validity have not been found to be consistently reliable…

The Trent Attribution Profile provides measures of locus of control and stability which can be further partitioned into individual attribution elements (ability, effort, task difficulty, luck). Reliability and validity data are reported. (Author/JKS)

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 reliability and validity of the Multidimensional-Multiattributional Causality Scale was examined for 350 American community college students, ranging in age from 17 to 59. The attributions of ability, effort, context, and luck emerged as well as distinctions between attributions related to academic success or failure. (Author/PN)

The Personal Reaction Scale was developed as a test for adults to measure their locus of control perceptions. It was administered to women college students, their parents, and parents of preschool children. Responses were factor analyzed to yield six factors: Fate, Social Self, Personal Self, Self-Determination, Luck, and Powerlessness.…

The reliability and validity of the revised California Psychological Inventory's (CPI) Vector 1 scale, a measure of introversion and extraversion, were studied with 345 college students (109 males and 236 females). Results support the scale as a valid measure of the introversion-extraversion construct of H. G. Gough. (SLD)

The aims of the present study were methodological and substantive; validity and reliability of the Optimism-Pessimism Test Instrument (OPTI) were tested. Moderate, but significant, correlations were found between OPTI and attitude toward school, self-concept, delay of gratification, and locus of control. (GK)
