Information functions are used to find the optimum ability levels and maximum contributions to information for estimating item parameters in three commonly used logistic item response models. Implications are discussed for applications such as adaptive testing and test construction. (SLD)

A study of the construction and factor validity of the Response to Child Incest Questionnaire, a self-report instrument for assessing commonly reported symptoms of adult survivors of incest, is reported. The instrument's usefulness as a pre- and post-treatment measure and further research needs are discussed. (MSE)

Presents a practical oral testing model that fits speaking tests into the syllabus and course grade, links teaching and testing approaches, tests interactive and individual performance, uses new and old materials, and compares impromptu and prepared performance. (Author/CB)

Outlines procedures for creating tests of knowledge that are consistent with training instruction by using test question formats. General patterns and specific question formats for recall, recognition, and application are given, and examples for creating sets of equivalent test questions are provided. (LRW)

Examines the theoretical underpinnings of the 1986 American Council for the Teaching of Foreign Languages (ACTFL) Proficiency Guidelines for reading, covering an historical perspective, the role of background knowledge, the process/product distinction, text types, and hierarchical and interactive reading models. (CB)

Studies the application of the letter-deletion procedure (LDP), which matches the advantages of both rational deletion and C-Tests and avoids their disadvantages to English-as-a-Second-Language tests. LDP flexibly reduces redundancy in a text by deleting letters in item words according to specified principles. (Author/LMO)

A development study involving 498 supervisors and a series of validity studies involving 531 adults identified primary dimensions, psychometric characteristics, and construct validation evidence for internal ability, internal propensity, and external propensity as domain-specific measures of feedback. Theoretical and practical extensions of the…

A procedure to detect differential item functioning (DIF) is introduced that is suitable for tests with a cutoff score. DIF is assessed on a limited closed interval of thetas in which a cutoff score falls. How this approach affects the identification of DIF items is demonstrated with real data sets. (SLD)

Methods are described, based on item response theory, that provide scaled scores, or estimates of trait level, for each summed score for rated responses or for combinations of rated responses and multiple-choice items. These useful methods avoid problems associated with response-pattern scoring. (SLD)

This book discusses adapting pencil-and-paper tests to computerized testing. Mention is made of models for graded responses to items and of possibilities beyond pencil-and-paper-tests, but the book is essentially about dichotomously scored test items. Contrasts between item response theory and classical test theory are described. (SLD)

This paper focuses on similarities of optimal design of fixed-form tests, adaptive tests, and testlets within the framework of the general theory of optimal designs. A sequential design procedure is proposed that uses these similarities to obtain consistent estimates for the trait level distribution. (SLD)

A new item-fit index is proposed that is both a descriptive measure of deviance of single items and an index for statistical inference. This index is based on assumptions of the dichotomous and polytomous Rasch models for items with ordered categories. A simulation study is described. (SLD)

Instrument refinement refers to any set of procedures designed to improve an instrument's representation of a construct. Five objectives of instrument refinement are discussed, and instrument refinement practices are reviewed in a discussion of its role in the process of developing theory and sharpening construct definition. (SLD)

To develop a comprehensive and uniform self-report questionnaire, 164 AIDS-related items were identified and placed into five groups: (1) factual knowledge; (2) misconceptions; (3) attitudes; (4) perceived susceptibility; and (5) perceived self-efficacy. These items originated from 18 AIDS studies involving children and adolescents and were…

The Acculturation Rating Scale for Mexican Americans was revised to measure cultural orientation toward Mexican and Anglo cultures independently. The revised scale is multifactorial, demonstrated strong construct validity with a sample of 379 college students representing five generational levels, and is capable of generating multidimensional…
