Item response theory (IRT) is currently the dominant methodological paradigm in educational and psychological measurement. IRT models are based on assumptions about the relationship between latent traits and observed responses, so the accuracy of the methodology depends heavily on the reasonableness of these assumptions. This dissertation consists…

Item response theory (IRT) refers to a family of mathematical models which describe the relationship between latent continuous variables (attributes or characteristics) and their manifestations (dichotomous/polytomous observed outcomes or responses) with regard to a set of item characteristics. Researchers typically use parametric IRT (PIRT)…

In April of 1982, the German Federal Armed Forces initiated the first empirical pilot project in the area of computerized adaptive testing (CAT). The configuration of hardware, psychological section, and physiological section is discussed, as well as two current problems (data transfer from the TEST 2000 microcomputer to a large sized computer for…

The classification of intelligence has been a prime interest to many for over three-quarters of a century. The Wechsler scales of intelligence and the development of factor analysis have both played major roles in the shaping of psychometric thought. An examination of this joint history by means of a review of the factor analytic studies of the…

A survey of 97 school psychologists found that the majority felt they needed additional training in administering, scoring, and interpreting the fourth edition of the Stanford-Binet Intelligence Scale. Thirty-four percent were using the fourth edition. Rank ordering of instruments of choice was: Wechsler scales, Kaufman Scale, old Stanford-Binet,…

This article defines test bias and reviews research methods most aptly applied postpublication to educational and psychological tests. Best methods for estimating bias in criterion-related or predictive validity and determining bias in construct validity across groups are explained. (Author/JDD)

School psychologists and education students and faculty were asked to distinguish between computer-generated and individually written psychological test comments and indicate cues used in making identifications. Even though results indicate correct identification did not differ significantly from chance, school assessment reports must provide more…

This study utilized a Latin Squares design to assess equivalence of computer and paper-and-pencil testing methods in a clinical setting with college students. No significant differences between scores on measures of anxiety, depression, and psychological reactance were found across group and administration format. Most subjects preferred…

Describes the chronic and acute subscales (SOMAC and SOMAA) of the Chinese Somatic Scale that was administered to 2150 Hong Kong secondary education students to measure their psychological well being. Results showed that both the SOMAC and SOMAA had acceptable reliability and validity status as compared with similar type tests. (GG)

The repeated psychological assessment of 41 high-risk infants during the first 2 years of life using the Mental Scale of the Bayley Scales of Infant Development was investigated. Analyses indicated that the infants' cognitive functioning remained fairly stable over the 2 years, particularly from age 6 months on. (Author/JDD)

The Kaufman Assessment Battery for Children (K-ABC) is purported to be less culturally biased than other, traditional measures of intellectual ability. The present study was designed to investigate three specific research questions: (1) Are there overall performance differences between Native American and non-Native American children on the WISC-R…

This paper reviews the now massive general literature showing that psychological tests are fair to minorities. This literature shows that there is no single group validity, there is no differential validity, and tests overpredict rather than underpredict minority job performance. Further evidence in regard to blacks is introduced from 51…

Past studies which have examined need levels have identified individuals as functioning at specific need levels without an adequate assessment of the intensity of each need or a clear comparison with other need levels. To address these issues, a self-report inventory using a modified paired comparison format was developed to assess need potencies…

This paper reviews literature on evaluating allegations of child sexual abuse, to determine whether there are systematic and significant differences on psychological tests between sexually abused and nonabused children, and whether these differences are a direct result of sexual abuse or a result of other coexisting factors that might cause…

This discussion of the design of computerized psychological assessment or testing instruments stresses the importance of the well-designed computer-user interface. The principles underlying the three main functional elements of computer-user dialogue--data entry, data display, and sequential control--are discussed, and basic guidelines derived…
