title: Simultaneous-successive factor structure of the WISC-R: a validation study.
abstract: It has been suggested that the Wechsler Intelligence Scale for Children--Revised (WISC--R) may usefully be interpreted in terms of a Simultaneous-Successive factor structure. A previous attempt to validate this hypothesis via factor analysis of 8 of the 12 WISC--R subtests was later shown to be an unreliable test of this model. The present study, performed upon 36 children, aged 6 1/2 to 12 1/2 yr., 45% female, 83% black, tested the validity of the two-factor model vis-á-vis the Kaufman Assessment Battery for Children (K-ABC), which is reported to have an unambiguous Simultaneous-Sequential (Successive) factor structure. Present results do not support a salient Simultaneous-Successive structure for the WISC--R, and clinicians should be wary of using the proposed two-factor model of the WISC--R for diagnostic or remedial purposes.
