The present study was designed to determine the number and nature of factors involved in Rotter's I-E Scale and to examine the question of the multidimensionality of the scale. Subjects were 329 college undergraduates. Principal components analysis was performed on the 23 pertinent items of the scale, followed by Varimax rotation. Multiple criteria indicated a 10-factor solution which accounted for 61% of the total variance. The first two factors were strongly similar to those reported previously. Results support Rotter's (1975) contention that subclasses within the scale will vary from sample to sample.

Evaluating appreciation of measures attending to pupil diversity (EMAD) is a scale for evaluating the understanding of measures describing pupils' cultural and diversity needs among the staff responsible for such measures in Spanish primary schools. Its 9 Likert-scale items correspond to the various types of action in this area that are currently being promoted in Spain. The principal objective of this study was to assess the scale's factor structure and internal consistency, to which end the scale was completed by the heads of the Departments of Orientation of 140 Spanish primary schools. Corrected item-total correlations and Cronbach alpha (.91) indicated adequate scale homogeneity. Principal components analysis followed by varimax rotation indicated two factors jointly accounting for 71.4% of total variance, one associated with actions involving modification of syllabuses, and the other with actions not requiring such changes. Cronbach alphas were .89 and .79 for the two factors.

Depression Scales

The Zemore Depression-Proneness Rating Scale was administered to 208 university students. A principal components analysis with varimax rotation identified three factors representing Negative Self-attitude, Performance Difficulty, and Lack of Appetite. Some similarity between the present factors and those of the Beck Depression Inventory was discussed. Because the scale overemphasizes cognitive components, attention to items on the somatic aspects of depression was suggested. However, it should be noted that depression-proneness appears to be the feature of Zemore's scale that sets it apart from other depression scales.

Questionnaire Measures

The reliability and factor structure of the Spanish version of the Object-Spatial Imagery and Verbal Questionnaire (OSIVQ) were assessed in a sample of 213 Spanish university graduates. The questionnaire measures three types of processing preferences (verbal, object imagery, and spatial imagery). Principal components analysis with varimax rotation identified three factors, corresponding to the three scales proposed in the original version, explaining 33.1% of the overall variance. Cronbach's alphas were .72, .77, and .81 for the verbal, object imagery, and spatial imagery scales, respectively.

The article reports reliability and validity of the Conceptions of Mathematics Questionnaires, based on responses of 154 undergraduate mathematics majors from four universities in South Africa. The reliability estimated as internal consistency had a Cronbach alpha of .84. To establish the validity, Principal components analysis with varimax rotation yielded a two-component solution accounting for 44% of variance. The components were interpreted as Fragmented Conceptions and Cohesive Conceptions of mathematics, as in Australia Since the factor solution was comparable to that reported in Australia, this result is a sufficient basis for the use of the questionnaire in South Africa.

Analysis of data from 255 U.S. pharmacists provides support for the consistency and validity of this short-form conservatism scale. The scale returned a coefficient alpha of 0.82, and principal components analysis yielded a strong general conservatism factor. Varimax rotation produced five factors consistent with the factor structure of the original Conservatism Scale.

Components Analysis

Factor analysis was performed on the Beck Depression Inventory with a university sample to examine its potential multidimensionality. A principal components analysis with an oblimin and varimax rotation produced a two-factor solution. These factors were labeled Cognitive–Affective and Physiological and accounted for approximately 39% of the common variance. This finding is consistent with multidimensionality of the inventory and with a similar study of college students. The commonalities of the two studies suggest the reliability (internal consistency) of the Cognitive-Affective and Physiological constructs among “minimally” depressed university samples.

Two Factors

The scores of 61 students on 7 newly constructed verbal tests were analysed using the methods of principal factor solution and varimax rotation. Two factors were extracted whose eigenvalues summed to 4.46 and accounted for 64% of the total variance. The convergent factor, which was responsible for 71% of the total common variance, was comprised of 5 tests, including a remote associates scale with significant loadings. The divergent factor accounted for the remaining 29% of the total common variance and was made up of 2 tests with significant loadings as well.

Black Sample

The present study sought to assess the factor invariance of Jones and Crandall's short form measure of self-actualization on a sample of 213 black undergraduates. A principal components analysis followed by a varimax rotation yielded five factors, four of which were interpretable. The obtained structure essentially replicated that of Jones and Crandall; however, there were differences that indicate the test cannot be assumed to be invariant across ethnic groups.

Data from 462 members of the general public were used to evaluate Hong's Psychological Reactance Scale. A principal components analysis with varimax rotation yielded a four-factor solution which was almost identical to previous research findings with a sample of college students, thereby indicating factorial stability. Reliabilities for the scale were satisfactory so use is recommended.

Four studies have yielded eight variables that are related to Greenberg and Jenkins' (1964) concept of language distance. These values for each of the 24 CCVCs of Greenberg and Jenkins' (1964) list 1 were correlated. The correlations were subjected to a principal components analysis with a varimax rotation. Three factors that account for 96% of the variance are reported. These are: (1) the perception and production of speech sounds, (2) language distance, and (3) the effort involved in pronouncing sounds subvocally.
