A computer program for item evaluation, reliability estimation, and test scoring is described. The program contains a variable format procedure allowing flexible input of responses. Achievement tests and affective scales may be analyzed. (Author)

Variance components from split-plot factorial design (SPF) were used to estimate reliability for schools and persons within schools. Reliability for persons within SPF and randomized block design (RB) schools were compared and reliability for SPF and RB design schools were compared. (Author/BJG)

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)

The use of Cohen's kappa index as a measure of the reliability of multiple classifications is developed. Special cases of the index as well as the effects of test length on the index are also explored. (JKS)

Cites evidence showing that the "natural order" found using the Bilingual Syntax Measure to measure morpheme order is not an artifact of the test. (Author/AM)

A modification of Hoyt's analysis of variance model for test analysis was proposed by Lu. A difficulty that may be encountered in using Lu's modification is examined, and a solution is proposed. (JKS)

Ordinal measurement is the rank ordering of individuals in a population. For ordinal measurement, the concept of an individual propensity distribution is his or her true score. Estimation of, as well as other aspects of the distribution, are discussed. (Author/JKS)

The usual formulas for the reliability of differences between two test scores are based on the assumption that the error scores are uncorrelated. Formulas are presented for the general case where this assumption is unnecessary. (Author/JKS)

Finding and interpreting lower bounds for reliability coefficients for tests with nonhomogenous items has been a problem for psychometricians. This paper presents a mathematical formula for finding the greatest lower bound for such a coefficient. (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)

The Personal Attribute Inventory was compared to the Adjective Check List as a measure of self concept on a sample of college students. The Personal Attribute Inventory showed strong correlation to two subscales of the Adjective Check List, and more stability over time. (JKS)

The Slosson Intelligence Test and the Shipley Institute of Living Scale were administered in a test-retest fashion to a sample of undergraduates. Correlations between the instruments were moderate and reliabilities for the instruments were moderate to low. (JKS)

Use of the coefficient of concordance is explained to be a simple technique for estimating reliability in small scale situation and is advocated as a valuable method for physical educators. (GW)
