Hierarchical analysis of neuropsychological test battery

Abstracts
suffered mild deficits in their ability to attend and concentrate, experienced psychoand visuo-motor slowing, have decreased gross motor grip strength and also experience greater clinical anxiety, depression and somatic symptoms than their controls as illustrated by their MMPI profiles. This supports previous findings on the effects of lead on neuropsychological function and illustrates the usefulness of the CNS/BI battery in conjunction with the MMPI as a tool in neurotoxicological investigations.
Haban, G. F. ,* Long, C. J.,? Lam. C.,* & Hile, D. H.* *New Medico Rehabilitation Center of Wisconsin and tMemphis State University. Hierarchical analysis of a neuropsychological test battery. Hierarchical analysis assumes that functional human abilities can be classified in ranks or orders. Narrow abilities appear low within the hierarchy and are subserved by broader abilities found at the upper levels of the hierarchy. The following study examined an array of neuropsychological tests from a hierarchical perspective. The subject sample was composed of 843 subjects who had received neuropsychological, intellectual, and memory evaluations as a part of a complete neuropsychological test battery. The correlation matrix of the age-corrected scaled scores was first derived. Cluster analysis (Ward’s method) was used to perform the hierarchical analysis. Factor analysis was used to determine major groupings of tests. The results of the hierarchical analysis demonstrated major groupings of neuropsychological tests that corresponded to perceptual and motor functioning, verbal and visualspatial memory, general intellectual functioning, attention and concentration, and complex integrative functioning. The structural relationships and similarity between the variables were discussed.
Olcese, R. P., & Sperling, T. B. Casa Colina Hospital. The Rehabilitation Orientation Test. In the past 10 years brain injury rehabilitation has grown from acute and subacute treatment to now include transitional living centers and long-term living care. Assessment to evaluate orientation has lagged behind this rapid growth. The Ranch0 Scale and the Glasgow Coma Scale have been effective in their use during the early stages of head injury. In 1979, the GOAT and others were developed to directly measure amnesia and disorientation after head injury. Their development and use substantiated that length and severity of PTA is at least as important a prognostic indicator of recovery as length of coma. However, these tests have been inadequate for the purposes of assessing orientation during long-term rehabilitation in a transitional living center. The purpose of this poster session is to propose an alternative measure for assessing orientation during this phase of functional rehabilitation. The Rehabilitation Orientation Test (ROT) is a brief questionnaire that can be used as an assessment as well as a therapeutic tool. It not only covers questions that are familiar and well rehearsed by normal adults but also orients patients to their current environments, rehabilitation priorities, and assesses the readiness for learning strategies, including organizational and sequencing skills. Work to establish the efficacy of this
