Four prominent oblique transformation techniques--promax, the Harris-Kaiser procedure, biquartimin, and direct oblimin--are examined and compared. Additionally, two newly developed procedures are presented and included in the comparisons. (Author/RC)

Data from 2-, 3-, 6-, and 7-point rating scales were analyzed to determine whether scale length affected response patterns. Results indicate that data configurations are relatively invariant with changes in number of scale points. (Author)

The factor structure in this study was remarkably consistent across the age range, with three factors emerging for each group: Verbal Comprehension, Perceptual Organization, and Freedom from Distractibility. The results of the study are discussed in terms of their clinical applications, particularly interpretation of WISC-R profiles. (Author)

Because of the still imperfectly understood basic factor structure of the MMPI, a Principal Components Analysis and Varimax Rotation was conducted on the MMPI item responses of 50 female undergraduate students of Education at Massey University. Eight factors were extracted. (Author)

Previous studies on common fears have been vague and have not met requirements for using factor analysis. To avoid some of these problems, a broader age range and a separate analysis of males and females were designed for a sample of 545 individuals, ages 15-89, who responded to 133 fear-scale items. "Death of a loved one" was the greatest fear…

A maximum likelihood estimation procedure is developed for the simple and the weighted additive models. The data are assumed to be taken by either one of the following methods: (1) categorical ratings--the subject is asked to rate a set of stimuli with respect to an attribute of the stimuli on rating scales with a relatively few observation…

LOW BIRTH WEIGHT CHILDREN WERE STUDIED LONGITUDINALLY TO DETERMINE WHETHER--(1) THE RELATIVE INTELLECTUAL IMPAIRMENT OF PREMATURE CHILDREN IS STATIC OR CHANGES WITH TIME, (2) A LOW BIRTH WEIGHT CHILD NOT NOTED TO BE IN NEUROLOGICAL DISTRESS COULD HAVE A POOR PROGNOSIS, AND (3) SPECIAL EDUCATIONAL AND EMOTIONAL PROBLEMS COULD ARISE AS A CONSEQUENCE…

THE RELATIONSHIP OF CERTAIN VARIABLES WITH THE ACADEMIC ACHIEVEMENT OF PUPILS OF SUPERIOR INTELLECTUAL ABILITY WAS PRESENTED. THE HYPOTHESIS USED WAS THAT HIGH ACHIEVING ACADEMICALLY GIFTED PUPILS COMPARED TO LOW ACHIEVING ACADEMICALLY GIFTED PUPILS RECEIVED THE BENEFIT OF MORE FAVORABLE PARENTAL ATTITUDES. THE PUPILS PERCEIVED THEMSELVES AS MORE…

Precipitated by questions of using Q methodology in television market segmentation and of the replicability of such research, this paper reports on both a reexamination of 1968 research by Joseph M. Foley and an attempt to replicate Foley's study. By undertaking a reanalysis of the Foley data, the question of replication in Q method is addressed.…

A procedure for estimating reliability in a factor analytic context, when reliability of the extracted factors is not an emphasis, is identified. The procedure is an extension of Dressel's work and might be applied in attitude measurement. It assesses how homogeneous the weighted original item responses are, when they are scored for pattern…

The purpose of the study was to establish dimensions of functioning accounting for interindividual variation in behavior in the later infancy period and to investigate the stability of the dimensional structure during the infancy period. Factor analyses were performed on parent questionnaire data for 357 infants, aged 11 to 15 months. An 8-factor…
