A common problem in practical educational research is that of perfect scores which result when latent trait models are used. A simple procedure for managing the perfect and zero response problem encountered in converting test scores into measures is presented. It allows the test user to chose among two or three reasonable finite representations of…

Factor structure underlying responses to the 373-item MMPI was found to be essentially identical to the factor structure previously defined from analysis of intercorrelations among the first 168 items. (Author)

Classical test construction and analysis procedures are applicable and appropriate for use with criterion referenced tests when samples of both mastery and nonmastery examinees are employed. (Author/BB)

The basis for selection of the calibration sample determines the kind of scale which will be developed. A random sample from a population of individuals leads to a norm-referenced scale, and a sample representative of abilities of a range of characteristics leads to a criterion-referenced scale.

Determines the reliability and discrimination values of each item; whether items judged highly intimate by Jourard discriminate between high and low disclosers more than items judged lowly intimate; and sex differences in disclosure. (Author)

Research performed pursuant to a grant from the Charles F. Kettering Foundation.

The susceptibility to faking on the Tennessee Self Concept Scale was examined among college students. Additionally, groups of respondents, instructed to respond in a "random" fashion to pre-determined numbers of items in the TSCS, were subjected to a plausibility analysis of their test response vectors using the Rasch measurement model.…

An index measuring the degree to which a binary response pattern conforms to some baseline pattern was defined and named the Pattern Conformity Index (PCI). One way of conceptualizing what the PCI measures is the extent to which each individual's particular response pattern contributes to, or detracts from, the overall consistency found in the…

A procedure for rapid screening of variables as potential moderators is presented and discussed. A moderator is defined as any variable which can be used to identify differentially predictable persons; or defined statistically by stating that if a predictor and a moderator are each divided into three or more categories and used as independent…

ALL TERMS IN CONTEMPORARY AMERICAN ENGLISH WHICH PERTAIN TO ASPECTS OF HUMAN BEHAVIOR OR PERSONAL CHARACTERISTICS WERE ASSEMBLED FROM AVAILABLE LEXICONS. THESE TERMS WERE CATEGORIZED INTO 15 RUBRICS ON THE BASIS OF JUDGMENTS OF THEIR FAMILIARITY, SPECIFICITY, AND CERTAIN BROAD SEMANTIC CRITERIA. SOME 2,800 TERMS WERE IDENTIFIED WHICH SEEMINGLY…

Statistical procedures employed in item analysis are based on the performance of the individual on a given test. If, however, one desires to assess the efficiency of some treatment, the researcher is interested in the performance of groups of students who received the treatment rather than in the performance of any one individual. In such cases…

To compare the means, reliability coefficients, and concurrent validity coefficients for four tests, two with and two without optional items; and to determine if pupils could select items that would improve their scores, 210 seventh grade pupils were first administered the seventh grade spelling subtest of the Iowa Tests of Basic Skills. They were…

Computers have been used successfully in test assembly following the cooperation of test specialists and computer specialists in systematic analyses of the test-assembly process. Systematic exploration of the item-writing process may well make it possible for the computer to take on some of the less creative portions of item writing. The current…
