Illustrates a multivariate approach to item analysis. Previous formulation is extended by investigating techniques simultaneously taking into account scale variance with the goal of reducing the average correlation between scales. Study examines problems in determining optimum values for combinations of item parameters selected for personality…

Reliability and validity data are reported for a questionnaire measure of individual differences in dominance-submissiveness. The 48-item questionnaire, which was balanced for response bias, had high internal consistency and correlated highly with other available measure of dominance. (Author/JKS)

A method to improve personality inventory validity by presenting positively keyed items from a single trait in descending order of endorsement and encouraging subjects to respond in terms of the resulting Guttman scale is presented. Experimental results show increases in reliability and validity. (Author/JKS)

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…

Various person reliability coefficients, including within- and between-occasion consistency measures, were investigated using the test and retest responses of 123 undergraduates on the Basic Personality Inventory (BPI). Results indicate person reliability may be a multidimensional concept, and that certain item consistency measures are confounded…

This study, using data for 200 psychiatric/chemical dependency patients, attempted to justify subscales of the Minnesota Multiphasic Personality Inventory (MMPI). Distributions of all possible split-half correlations for certain research scales of the MMPI revealed negative skewness resulting in spuriously lowered reliability estimates. The scales…

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)

Confirmatory factor analysis using the LISREL computer program was performed on test scores from 500 workshop participants (adults) taking the Myers-Briggs Type Indicator--Expanded Analysis. Results, cross-validated with 500 other scores, support 4 factors as well-defined constructs. Improvements are suggested for subscale reliability. (SLD)

Construction and validation of the Personality Adjective Inventory, a new test of personality based on Murray's need-press theory and following the lead of the Personality Research Form is described. The inventory shows excellent psychometric properties across several measures of reliability, stability, and validity. (Author/LMO)

Four hypotheses regarding stability of response process and response in personality testing are tested and supported. (RC)

Explores the usefulness of a short version of the Minnesota Multiphasic Personality Inventory (Mini-Mult) in a university counseling center as well as determines whether earlier results of investigations of the Mini-Mult could be replicated with a sample of college males and females demonstrating no gross abnormalities. (RC)

The reliability and item homogeneity of personality scales are in part dependent on the content domain being sampled, and this characteristic reliability cannot be explained by item ambiguity or scale length. It is suggested that clarity of self concept is also a determinant. (Author/JKS)

Two major purposes were to (1) appraise the extent to which relatively naive item writers can produce valid personality scales, and (2) compare these scales with scales derived from other strategies, particularly those employing empirical methods using an external criterion. (Author/RC)
