The purpose of the present study was to provide the means to evaluate the "interval-scaling" assumption that governs the use of parametric statistics and continuous data estimators in self-report instruments that utilize Likert-type scaling. Using simulated and real data, the methodology to test for this important assumption is evaluated…

The paper presented evidence of the criterion related validity of several Comprehensive Ability Battery (CAB) tests relative to criterion variables representing first year college achievement. Information regarding the criterion related validity of nontraditional tests of the CAB reflecting divergent production hypothesized to be associated with…

Procedures used to develop and validate an instrument appropriate for assessing the status of teacher evaluation practices in schools are described. Data are presented substantiating the reliability and validity of the instrument, as well as its sensitivity to differences in teacher evaluation programs. (Author/GK)

The Piers-Harris Children's Self-Concept Scale was administered twice to a sample of elementary school pupils and both sets of data were factor analyzed. Results led the authors to question the factor stability of the instrument. (Items are included). (JKS)

This paper presents the development of a new measure of locus of control for adults, the Internal Control Index. Analysis of a field test and a junior college administration indicated an estimated reliability of .84, the presence of a strong principal component, two replicable factors, and evidence for convergent validity. (Author/BW)

The Belief Polarity Scale, an index of racial prejudice, was administered to 76 educators of mixed racial background before and after an interracial human relations workshop. Analysis of variance revealed that polarity scores discriminated by race and that change in polarity was a function of pretest dogmatism. (Author/BW)

The factorial validity was investigated of a 55-item instrument designed for use in a recently desegregated school district to assess staff training needs. Factor analysis supported the validity of the instrument. (The 55 items are presented). (Author/JKS)

A 20-item scale, based upon the Estes Reading Attitude Scale, was constructed to measure elementary students' attitudes toward reading. Results supported its reliability and validity for third, fourth, and fifth graders. (The scale is included). (JKS)

The Attitudes toward Bilingual Education scale was shown to be valid with respect to its ability to discriminate between proponents of bilingual education and a general population. (The 23-item scale is included). (Author/GDC)

The Resident Evaluation Form (REF) was developed to assess resident physicians' clinical performance. This research sought to empirically evaluate the intuitively derived REF scales representing areas of clinical performance: interpersonal ability, cognitive ability, clinical skills, and professional attributes. Analysis yielded cognitive…

Cognitive and affective scales for assessing computer attitudes were administered to 2,525 students and educators. Results supported test validity and reliability. Generally positive cognitive attitudes were found, as well as a rejection of negative affective attitudes. (The 14 items are included) (GDC)
