The apparent stability of the three-factor solution across sex and age supports the interpretation that Wechsler Intelligence Scale For Children-Revised (WISC-R) factor scores are independent of child's sex and age. Construct validity is documented across numerous demographic variables. (Author)

Investigated factor structure of the Stanford-Binet Fourth Edition using collaboration matrix from the standardization sample of 1,695 children aged 2 through 6 years, 1,586 children aged 7 through 11 years, and 1,728 participants aged 12 through 23 years. The results revealed the large first factor that resembled general intelligence, with little…

Performed exploratory factor analysis of the responses of 458 older adults, aged 60 to 100 years, to the Adult Manifest Anxiety Scale-Elderly Version (based on a scale by J. Taylor, 1953). Found a three-factor structure of anxiety consistent with current theories of anxiety that supports the construct validity of the measure. (SLD)

Responses of 871 adults to the Adult Manifest Anxiety Scale-Adult version (AMAS-A) were factor analyzed using the method of principal axis factoring with promax rotation. Factor analysis yielded a four-factor solution: three anxiety factors (Worry/Oversensitivity, Stress, and Physiological Anxiety) and a Lie factor. The AMAS-A's three-factor…

Six methods of measuring factorial similarity were compared with regard to outcome based on two large data sets, one for an intelligence test and the other for a personality test. All indexes yielded comparable results. Comparing factors determined at random, all indexes yielded comparable results leading to a conclusion of dissimilarity.…

Responses to the Revised Children's Manifest Anxiety Scale (RCMAS) were factor analyzed with children (N=4972) between 6 and 19 years. Three anxiety factors emerged that were consistent with earlier studies. Factor structure of the RCMAS is for the most part invariant with regard to race and sex. (Author)

The 1976 Metropolitan Readiness Test was factor analyzed from responses of (N=408) beginning first graders. Results indicated a single general readiness factor, consistent with prior research, best described the battery of eight subtests. This factor was invariant across sex when separate analyses for males and females were compared. (Author)

The six subtests comprising the Metropolitan Readiness Tests were factor analyzed separately for White females, White males, Black females, and Black males. A single factor best described the structure of the test for each group. The factor structure was essentially invariant with regard to race and sex variables. (Author/CTM)

To test the validity of the Wechsler Intelligence Scale for Children-Revised (WISC-R) for minority groups, factorial similarity across race was investigated with separate principal-factor analyses for White and Black children from the nationally representative WISC-R standardization sample. On every measure, the White and Black groups were highly…
