title: Predicting scores of the Halstead Category Test with the WAIS-III.
abstract: The Halstead Category Test (HCT) and the Wechsler Adult Intelligence Scale (WAIS) are two of the most widely used neuropsychological tests. Often assessment conclusions are dependent upon the comparison of these measures. Therefore, it is crucial for clinicians to know how they relate to one another. This study examined the relationship between the HCT and the WAIS-III with undergraduate psychology students. Correlational analyses were conducted between HCT scores and WAIS-III subtests, Verbal and Performance IQ, and Full Scale IQ scores. Additionally, the new WAIS-III scales (Letter-Number Sequencing, Matrix Reasoning, and Symbol Search) were further examined. Regression analyses were run to develop predictor equations for the HCT using VIQ, PIQ, and FSIQ. Finally, predictor tables were generated between the HCT and VIQ, PIQ, and FSIQ to provide assessment of brain dysfunction for clinical use.
