Conducts a comparative investigation of selected item analysis programs currently available which could serve as a base for judicious program selection and use. (RC)

The Q Sort method is a rank order procedure. A FORTRAN program is described which calculates a total value for any group of cases for the items in the Q Sort, and rank orders the items according to this composite value. (Author/JKS)

Some suggestions for computations are given for simultaneous determination of squared multiple correlations for all measures. (Authors)

The polyserial and point polyserial correlations are discussed as generalizations of the biserial and point biserial correlations. The relationship between the polyserial and point polyserial correlation is derived. Some practical applications of the polyserial correlation are described. (Author/JKS)

A new look at latent trait models is proposed. The event of an item being solved by a person is related to a person-specific random component and an item-specific random component. This allows for the interpretation of item discriminating power in terms of a product-moment correlation. (Author/JKS)

Since 1918, more than 280 measures of depressive severity have been developed and published. These measures differ in content, response format, and objectives. This article examines (a) the characteristics of scales developed in the past 80 years, and (b) the frequency with which different scales have actually been used in basic science and…

A foundational mission of our public schools is dedicated to preserving a democratic republic dependent on a literate and actively engaged citizenry. Civic literacy is essential to supporting the rights and responsibilities of all citizens in a democratic society. Civic knowledge is the foundation of our citizens' civic literacy. National…

N. Stewart, G. D. A. Brown, and N. Chater's relative judgment model includes three core assumptions that enable it to predict accurately the vast majority of "classical" phenomena in absolute identification choices, but not the time taken to make them, including sequential effects, such as assimilation and contrast. These core assumptions, coupled…

Content balancing is an important issue in the design and implementation of computerized adaptive testing (CAT). Content-balancing techniques that have been applied in fixed content balancing, where the number of items from each content area is fixed, include constrained CAT (CCAT), the modified multinomial model (MMM), modified constrained CAT…

The Personality Psychopathology Five (PSY-5) is a model of personality psychopathology assessed in adult populations with a set of Minnesota Multiphasic Personality Inventory-2 (MMPI-2) scales. The authors examine the reliability and validity of recently developed lower-order facet subscales for each of these five domains, with an emphasis on…

This article reports a reliability study of two versions of the Vocabulary Levels Test at the 5000 word level. This study was motivated by a finding from an ongoing longitudinal study of vocabulary acquisition that Version A and Version B of Vocabulary Levels Test at the 5000 word level were not parallel. In order to investigate this issue,…
