This paper presents theory concerning the relationships between reliability, misinformation and item discrimination coefficients. It is shown that, to the extent that misinformation rather than ignorance causes examinees to miss multiple-choice items, higher item discrimination coefficients and lower difficulty indices may be expected. Data were…

Two forms of the CEEB English Composition Test and four tests constructed by the University of Illinois Rhetoric department were compared as final examinations for the freshman English composition course. Results from 2545 students indicate that while the CEEB tests discriminate more between students and are more reliable, the departmental tests…

A good criterion-referenced test item is defined as the one which allows the individual to answer correctly if he masters the criterion behavior represented by the item and answer incorrectly if he actually does not master it. Therefore, a good discriminating item for criterion-referenced tests is the one which has a larger proportion of correct…

Because previous reports have suggested that the lowered validity of tests scored with empirical option weights might be explained by a capitalization of the keying procedures on omitting tendencies, a procedure was devised to key options empirically with a "correction-for-guessing" constraint. Use of the new procedure with Graduate…

Cognitive style research is hindered by a variety of poorly described measures and style classifications and the use of small samples. This study describes and compares three measures of three postulated dimensions of cognitive style: impulsivity/reflectivity; internal/external locus of control; and field dependence/field independence to determine…

Reliability and validity data are presented for three orthogonal measures of temperament: trait-pleasure, trait-arousal, and trait-dominance. Reliability coefficients for the three scales were .91, .60, and .84, respectively. Intercorrelations among the three scales were insignificant and low. (Author/JKS)

Three fear of success measures correlated positively with the Alpert Haber Debilitating Anxiety Scale. Correlations between the Pappo Fear of Success Questionnaire (FOS) and the Zuckerman and Allison Fear of Success Scale (FOSS) were significant and positive. The Horner Scoring System was not significantly correlated with the FOS or FOSS. (EVH)

An unweighted and two weighted measures of children's giving were used in two experiments designed to enhance children's prosocial development. This paper describes the rationale for the construction of the measures, presents data on test-retest reliability and validity as well as treatment outcomes for the two experiments. (Author/LMO)

Describes a study conducted at DeKalb Community College to compare placement levels established by the college's in-house Reading, English and Mathematics (REM) Test with Scholastic Aptitude Test scores. Discusses REM placement levels and their course alignments, internal challenges to the placement levels, and correlation study findings. (DMM)

This review of issues about correcting for attenuation concludes that the basic difficulty lies in being able to identify and equate sources of variance in estimates of validity and reliability. Recommendations are proposed for cautious use of correction for attenuation. (Author/CM)

This study examined the reliability and validity of the Preference Inventory (PI) as a measure of adult creative potential. Capabilities of creatively productive persons include mental examination and manipulation of ideas, curiosity, need to create, and originality. Undergraduates' PI scores were significantly correlated with four other indices…

The ability of the Stanford Early School Achievement Test (SESAT) to predict scores on the Stanford Achievement Test (SAT) was assessed, using pupils in grades 1 and 2 from a large midwest suburban school district. Observed SESAT-SAT correlations ranged from .257 to .723. Author/CTM)

An alternative to the uniform probability distribution model for ordinal data is considered. Implications for statistics and for test theory are discussed. (JKS)

Scoring of response vectors to give maximum test-retest correlation is investigated. A general method is given for finding the best scores, deriving them for the normal factor model, and showing that for a standard model for binary response it is easy to approximate the best scores. (SLD)

A study of 233 individuals with severe mental retardation examined the validity of the Diagnostic Assessment for the Severely Handicapped-II (DASH-II) through correlation with the Aberrant Behavior Checklist (ABC). DASH-II as a whole was found to have a high degree of convergent validity with the ABC total score. (CR)
