Describes two broad-band factor scales of marital distress constructed to supplement existing profile scales of the Marital Satisfaction Inventory. The two new scales, labeled Disaffection and Disharmony, both discriminated between normative and clinical samples. Distinct distributions support the concept of two separate, interactive components of…

Mathematical and statistical relationships between factor analysis and smallest space analysis are discussed. As spatial analysis of correlation matrices, factor analysis is a special case of smallest space analysis. The two differ in six ways: Shepard diagram, dimensionality, correction for communality, similarity coefficients, regions versus…

Issues related to the decision of the number of factors to retain in factor analyses are identified. Three widely used decision rules--the Kaiser-Guttman (eigenvalue greater than one), scree, and likelihood ratio tests--are investigated using simulated data. Recommendations for use are made. (Author/JKS)

The performance of four rules for determining the number of components (factors) to retain (Kaiser's eigenvalue greater than one, Cattell's scree, Bartlett's test, and Velicer's Map) was investigated across four systematically varied factors (sample size, number of variables, number of components, and component saturation). (Author/JKS)

Investigated relationships between empirically determined dimensions of problem behaviors and profile scales of the Personality Inventory for Children. Correlation matrices allowed identification of scale to correlates and their variation by age or sex and facilitated estimates of generalizability of the data. Results provided evidence of scale…

To assess the stability of the factor structure of the Instructional Improvement Questionnaire (IIQ), factor analyses were run for 1973, 1974, and 1975 results, partialling out three variables: expected grade, percent taking the course as an elective, and student's year. The factors were stable over the three years. (Author/BW)

The purpose of this study was to investigate the structure of motor proficiency in a sample of 765 children between the ages of 4 1/2 to 14 1/2 years. The study was conducted as one aspect of the standardization of a motor proficiency scale, the Bruininks-Oseretsky Test of Motor Proficiency. (Author/SJL)

The incremental validity of factor scores from the Wechlser Intelligence Scale for Children-III (WISC-III) in predicting scores on the Wechsler Individual Achievement Test (WIAT) was studied in 283 nonreferred children and 636 referred for evaluation. The Full Scale IQ of the WISC-III was the best predictor of WIAT achievement. (SLD)

Results of confirmatory factor analysis of data from 5 samples (308 financial professionals, 578 employees, 588 management students, 728 employees in South Korea, and 250 employees in Bangladesh) support the convergent and discriminant validities of subscales of the Leader Power Inventory (M. A. Rahim, 1988). (SLD)

The consequences of underextracting factors and components within and between the methods of maximum likelihood factor analysis and principal components analysis were examined through computer simulation. The principal components score and the factor score estimate (T. W. Anderson and H. Rubin, 1956) tended to become different with…

Describes the initial development and validation of an adolescent-specific multi-dimensional scale to measure motivation to change related to substance use. Preliminary psychometric findings reveal adequate internal consistency and a factor structure corresponding to the inventory's subscales. Implications for future research and for practice are…

Studied the constructs underlying the Ball Aptitude Battery (Ball Foundation; BAB) in 3 studies involving 329 and 365 adults and 175 ninth graders and in a reanalysis (study 4) of previous BAB data. Results show that "g" plays a significant but not dominant role in the BAB, which measures abilities needed for assessing person-job fit.…

Administered the Dutch adaptation of the Psychopathic Personality Inventory (R. Lilienfeld and B. Andrews, 1996) to 314 adults in Flanders and studied the factorial structure and scale characteristics. Results support the usefulness of the instrument. (SLD)

Three attachment style scales were developed. The factor structure of the attachment style construct was supported through exploratory factor analysis of attachment style scores from 1,181 and 545 recent college graduates. Additional evidence for score validity is presented, based on a measure of the Big Five personality traits. (SLD)

Four studies of the factorial validity of the Spatial Learning Ability Test (SLAT), involving 431 undergraduates, were summarized to elaborate nomothetic span. These studies support the SLAT as a spatial processing measure. The SLAT, compared to a test with the same item type, was a more pure measure of spatial ability. (SLD)
