A new 22-item measure of an individual's tolerance for ambiguity, the Multiple Stimulus Types Ambiguity Tolerance (MSTAT-I), is described. The measure addresses characteristics of ambiguous stimuli and reactions to perceived ambiguity. Evidence from 148 undergraduates for reliability and convergent and discriminant validity is presented in support…

Discusses methods that may be applied to the evaluation of hypermedia, based on six models described by Lawton. Techniques described include observation, self-report measures, interviews, automated measures, psychometric tests, checklists and criterion-based techniques, process models, Experimentally Measuring Usability (EMU), and a naturalistic…

Examined psychometric properties, including factor structure, of the Index of Responding and assessed implications of that structure for counseling research. Index of Responding was used as measure of empathy with 70 elementary and secondary teachers enrolled in undergraduate program in guidance counseling. Factor analysis yielded one wide-loading…

Reports on development and psychometric properties of Feminist Family Therapy Scale (FFTS), a 17-item instrument intended to reflect degree to which family therapists conceptualize process of family therapy from feminist-informed perspective. Found that the instrument discriminated between self-identified feminists and nonfeminists, women and men,…

Predictive validity of Education Participation Scale Alternative form was demonstrated by relating interview data and estimates to actual scores. Responses from 845 North American and Asian adults entered into discriminant function equations successfully classified 60 percent by gender, 25 percent by age, and 65 percent by ethnicity. Soundness of…

The derivation of the variance of similarity judgments is made from the 3-D process in nonlinear psychophysics. The idea of separability of dimensions in metric space theories of similarity is replaced by one parameter that represents the degree of a form of interdimensional cross-sampling. (SLD)

Examination of the role of psychometrics in the development of multiple-choice tests and performance-based assessments and consideration of validity and reliability issues leads to this conclusion: Choice of assessments for instruction or large-scale accountability depends on which is more appropriate for the particular purposes. Taxonomic…

A unidimensional model for responses to statements that have an unfolding structure was constructed from the cumulative Rasch model for ordered response categories. A joint maximum likelihood estimation procedure was investigated. Analyses of data from a small simulation and a real data set show that the model is readily applicable. (SLD)

A class of models is presented for gamma distributed random variables. These additive, multiplicative, and combined additive-multiplicative models are more flexible than classical linear models with respect to the structure that can be imposed on expected values. As a special case, a class of psychometric models for reaction times is presented.…

Two nested structural models are developed to determine whether test-session behaviors affect the manner in which intelligence is measured or influence the constructs being measured. Results indicate that test-session behaviors play a larger role influencing the mechanisms of measurement than on the constructs of intelligence. (Author/EMK)

Studied effects of administration mode [computer adaptive test (CAT) versus self-adaptive test (SAT)], item-by-item answer feedback, and test anxiety on results from computerized vocabulary tests taken by 293 college students. CATs were more reliable than SATs, and administration time was less when feedback was provided. (SLD)

Describes the development and evaluation of the Choice Questionnaire, an instrument designed to measure the availability of choice to people with intellectual disability. The scale can be administered by interviewing the consumer or may be completed by a knowledgeable proxy. Very satisfactory reliability and validity have been determined.…

Studied the psychometric characteristics of a developmental assessment in mathematics composed of 19 performance tasks for students in grades K-3. Reports convergent validity coefficients, internal consistency reliability, interrater reliability, and task orderings. (SLD)

Two studies examined psychometric properties of a new criterion Q-sort for children's emotion regulation and autonomy. Multitrait-multimethod matrix and factor analyses indicated impressive convergence among the emotion regulation Q-scale and established affect regulation measures. The new scale was not discriminable from measures of related…

Eight psychometric instruments were administered to 10 elite male Portuguese orienteers. The cognitive process involved in decision making did not differ between the best orienteers and the others. This group of athletes had a high capacity for work realization and a strong need to be in control of interpersonal situations. (Author/SV)
