Various item selection techniques are compared on criterion-referenced reliability and validity. Techniques compared include three nominal criterion-referenced methods, a traditional point biserial selection, teacher selection, and random selection. (Author)

A scale was developed to measure attitude toward school among elementary school pupils. Scores on the questionnaire were positively correlated with teacher ratings of school attitudes, non-verbal ability, standardized tests of school achievement and self-concept scores for a sample of fourth grade pupils.

Discusses study involving parcels of homegenous items as opposed to item factoring. (SDH)

A model of test item dependency is presented and used to illustrate the effect that violations of local independence have on the behavior of item characteristic curves. The dependency model is flexible enough to simulate the interaction of a number of factors including item difficulty and item discrimination, varying degrees of item dependence,…

A new indicator of item difficulty, which identifies effectiveness ranges, overcomes the limitations of other item difficulty indexes in describing the difficulty of an item or a test as a whole and in aiding the selection of appropriate ability level items for a test. There are three common uses of the term "item difficulty": (1) the probability…

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. (Author/BB)

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…
