This study developed a semantic differential (SD) instrument to measure self-concept that was not influenced by social desirability. An alpha factor analysis of 53 SD scales produced five interpretable factors for the females and five interpretable factors for the males. A subsequent investigation of the convergent validity of each of the factors…

A procedure is described for increasing the reliability of tests after they have been given and for developing shorter but more reliable tests. Eight tests administered to 200 graduate students studying educational research are analyzed. The analysis considers the original tests, the items loading on the first factor of the test, and the items…

Research reported in this paper considered the construct validity of a trial essay administered in 1985-87 Medical College Admission Test (MCAT). The addition of the essay caused the non-science factor observed in previous MCAT research to be more strongly defined. (Author/LMO)

The reliability and factorial validity of the Self Concept as a Learner Scale was studied, using 12-year-old Anglo-Australians. Reliability was acceptable for total scale and three subscales (task orientation, problem solving, and class membership), but not motivation. The validity of the factorial subscales was not confirmed. (GDC)

The construct validity and reliability of the Porter Needs Satisfaction Questionnaire (adapted) for educators were examined. Results did not support its use as suggested by Porter. Suggestions for its revision and alternate use are presented. (Author/GDC)

The purpose of this study was to provide cross-cultural validation evidence about the factorial structure, reliability, and correlates of the Attitudes Toward Mainstreaming Scale for samples of education students, teachers-in-training, and elementary school teachers in New Zealand. (Author/PN)

The internal-external locus of control scales of Rotter and Levenson and the Marlowe-Crowne Social Desirability Scale were completed by 156 undergraduates. The three-factor structure underlying Levenson's questionnaire was clearly confirmed. Some new evidence for the multidimensionality of Rotter's scale was also presented. (Author/GDC)

A short measure of trait and state negative and positive affect, the Chinese Affect Scale, was developed for Chinese-speaking people and tested in Hong Kong with 306 community adults and 314 college students. Scores had reasonable internal and retest reliabilities and high convergent and discriminant validity. (SLD)

The validity and reliability of a scale measuring attitudes toward foreign language were studied with 536 high school seniors. Results of principal components analysis identified five interpretable dimensions and suggested the need to improve the internal structure of the measure. (SLD)

Cognitive holding power is defined as a characteristic of the learning setting that presses students into different kinds of cognitive activity. Development of an instrument to measure cognitive holding power and studies of the instrument's reliability with over 1,500 Australian technical college students are reported. (SLD)

Data from 6,472 South Carolina residents aged over 55 years support the reliability of S. Katz's Activities of Daily Living scale when data are collected by self-report telephone interview. Results indicate that telephone interview methods are a fast, inexpensive, and safe way to collect data for research and policy formation. (SLD)

The purpose of this study was to obtain validity and reliability indexes for scores on a 12-item scale measuring family perspectives on extended school year (ESY) programs for students in special education. Responses from 128 families with a child potentially eligible for ESY programs indicated that a two-component model was both valid and…

The reliability and construct validity of ratings for the Autism Behavior Checklist were examined with a sample of 198 children diagnosed with autistic disorder and conditions often confused with autism. Alpha coefficients for the five scales of the ABC as well as the Total Score were reported and the factor structure of the ABC was examined…

Objective: The aims of this study were to examine (1) the psychometric properties of the Childhood Trauma Questionnaire [CTQ; Bernstein, D., Fink, L., Handelsman, L., Foote, J., Lovejoy, M., Wenzel, K., Sapareto, E., & Ruggiero, J. (1994). Initial reliability and validity of a new retrospective measure of child abuse and neglect. American…

The Beck Depression Inventory-II (BDI-II; A. T. Beck, R. A. Steer, & G. K. Brown, 1996) is a widely used measure of depressive symptomatology originally authored in English and then translated to Spanish. However, there are very limited data available on the Spanish translation. This study compared the psychometric characteristics of the…
