The consistency of factor structure of Osgood's semantic differential was examined in three different adult samples, aged 18 to 87. Three different concepts were used: the University of West Florida, Myself, and Death. Results indicated consistency for the evaluation factor and moderate consistency for potency and activity.

The WISC-R was investigated by using measures of profile (multivariate) reliability to determine its most reliable dimensions and the precision and similarity of the multivariate structure across age groups. The structure of the WISC-R subscales was stable across age groups. Two strategies for the interpretation of WISC-R profiles are offered.…

Underlying constructs of the Nowicki-Strickland Locus of Control Scale for Children (NSLOCSC) were identified through factor analysis and cross-validated with two similar samples of high school students. The two resultant dimensions appeared to measure Social Control (six items) and Self Control (two items). (Author/GK)

The Internal Structure of the New Study Processes Questionnaire (Biggs, 1979) was investigated with samples of Australian and Filipino university students. The internal consistency reliabilities, item and subscale factor analysis, were quite favorable for the Australian sample; however, results indicated that the instrument may not be suitable for…

Offers suggestions for proper procedures for authors to use--and some pitfalls to avoid--when writing studies using factor analysis methods. Discusses distinctions among different methods of analysis, the adequacy of factor structure, and other notes of caution. Encourages authors to ensure that their research is statistically sound. (RJM)

Demonstrates how data smoothing procedures--procedures commonly used in the development of continuous test norms--can provide better estimates of the reliability, uniqueness, and general factor characteristics for the Wechsler Intelligence Scale for Children, third edition, subtests. Suggests that such procedures are applicable to other test…

The Aiken Attitude to Mathematics Scale (L. Aiken, 1974, 1979) was administered to 430 adult students in a tertiary preparation program, and the factorial validity of the scale was investigated through exploratory factor analysis. Two factors were extracted with high reliabilities, as opposed to Aiken's four-factor structure. (SLD)

The Youth Self Report was used in a Swiss epidemiological study with 1,093 subjects aged 10 to 17 years. Internal consistency was good for three second-order factors, but it was less satisfactory for almost all syndrome scales. In general, internal consistency coefficients were slightly lower than for the U.S. sample. (SLD)

This article describes the development and psychometric properties of the Counselor Burnout Inventory (CBI), which is designed to meet the needs of the counseling profession by assessing burnout in counselors. Factor structure, concurrent validity, internal consistency, and test-retest reliability of the CBI scores are reported. Implications for…

Some years ago, B. Efron and his colleagues developed bootstrap resampling methods as a way of estimating the degree to which statistical results will replicate across variations in sample. A basic problem in the multivariate use of bootstrap procedures involves the requirement that the results across resamplings must be rotated to best fit in a…

A study examined the extent to which a 19-item short form of the Speech Evaluation Instrument (SEI) is a reliable instrument, what factor structure emerges from the analysis, and how that factor structure compares to that reported for the 30-item long form of the SEI. Subjects, 606 undergraduates enrolled in speech communications classes at two…

The present study was designed to examine the construct validity, reliability, item difficulties, discrimination indices, effectiveness and efficiency of the CCAT test. (Author)

The Ohio Vocational Interest Survey (OVIS) has been used as an interest measurement tool measuring student interests toward jobs dealing with data, people and things. The purpose for the present paper was to determine the consistency of the OVIS for measuring these three dimensions through factor analysis. The research findings demonstrated which…
