A Comparison of Paranoid Schizophrenics and Schizo-Affective, Depressed Type Schizophrenics, Utilizing Gittinger's Personality Assessment System

Harlan, Teresa A. 08 1900 (has links)
This study hypothesized that paranoid schizophrenia and schizo-affective, depressed type schizophrenia could be differentiated by the Internalizer-Externalizer, Regulated- Flexible, and Role Uniform-Role Adaptable dimensions of the Personality Assessment System. The Personality Assessment System methodology utilizes the Wechsler Adult Intelligence Scale to measure these dimensions. All hypotheses were statistically confirmed. The difficulty of applying the Personality Assessment System to psychopathological regressive states is cited. Recommendations include utilizing the Personality Assessment System with other groups in the institutional setting and within diagnostic categories.

The detection of biased responding on the Wechsler Memory Scale- III and Wechsler Adult Intelligence Scale- III

Brulot, Magali Marie-Pierre 16 August 2018 (has links)
Growing demand on the limited resources available to head-injured individuals, emphasizes the need for accurate diagnosis and proper allocation of funds. Consequently, neuropsychologists are increasingly asked to render opinions regarding the validity of cognitive deficits reported following head injury. Detection of biased responding has typically been approached through the use of symptom validity measures and/or evaluation of performance patterns on standardized neuropsychological tests. This dissertation examined patterns of malingered performance on the Wechsler Adult Intelligence Scale-III (WAIS-III), Wechsler Memory Scale-III (WMS-III), and a self-report measure of physical and psychological symptoms. In addition, attempts were made to address several methodological concerns noted in previous analogue studies (e.g., allocation of preparation time). Malingered performance was compared to that of a normal control group (NC = 34) and a group of mildly head injured individuals (MHI = 22). Results revealed that the simulating group (SIM = 32) endorsed more subjective concerns than the NC group. On the cognitive measures, simulators showed a tendency towards general suppression of performance versus specific areas of deficit (e.g., attention). Specifically, the SIM group suppressed their performance on the WAIS-III, but not typically enough to differentiate them statistically from either the NC or MHI groups. The SIM group's performance on the WMS-III was more in keeping with the overall suppressed performance pattern reported in previous research. Although simulators often performed significantly worse than the NC group, they did not generally suppress their performance excessively when compared to the MHI group. Results obtained in this study may reflect the use of more detailed instructions or the preparation time allocated to the SIM group. Overall, these findings emphasize the importance of incorporating multiple detection measures to assure the accurate assessment and diagnosis of head injury. / Graduate

The effects of level and quality of education on a South African sample of English and African first language speakers, for WAIS-III digit symbol-incidental learning

Donnelly, Martin Joseph Rhodes January 2001 (has links)
This study examined the effects of level and quality of education on WAIS-III Digit Symbol-Incidental Learning performance. The Pairing and Free Recall measures were administered to a South African sample (N = 68, age range 19-30), which was stratified for English and African language, level of education attained (Grade 12s and Graduates) and quality of education (advantaged and disadvantaged schooling). Results yielded no significant main or interaction effects between acculturation factors of level and quality of education. Normative guidelines of 13 or more pairs and 8 or more free recall symbols, appropriate to a non-clinical sample in a multicultural setting, are provided. Digit Symbol-Incidental Learning proved to be a culture-fair test, which contributes to its clinical utility as a sensitive memory screening tool.

The development of a WAIS-III short form for use in South Africa

Rust, Annegret L January 2000 (has links)
The Wechsler Adult Intelligence Scale - 3rd Edition (WAIS-III) is the newest of the internationally recognised Wechsler family of intelligence tests. It has been improved in terms of its psychometric properties, neuropsychological assessment abilities and its content. This test is in the process of being standardised by the Human Sciences Research Council (HSRC) in South Africa. As the adapted South African version will be available shortly for use in the multicultural circumstances of South Africa, the application of the various aspects of this test needs to be investigated. This test is very comprehensive and thorough, however its one disadvantage is that it takes on average three hours to administer in its entirety. Thus there is a need to find ways in which to abbreviate the test for particular purposes when time is limited, for example in research, brief clinical assessments or neuropsychological screenings. The concept of abbreviating tests, including the earlier Wechsler intelligence test can be traced back to 1917, when it was asked if all the items on the Binet-Simon scale were required to give an accurate assessment of IQ (Levy, 1968). Since then there have been many short form suggestions made, with many different considerations in mind. These can be divided into two main approaches or methods. Firstly, the number of subtests of the scale can be reduced. Thus with the WAIS-III which consists of 14 subtests in total, an option is to use, for example only four of the subtests to get an estimate of a person's IQ. Secondly, the number of items in each subtest can be reduced. Thus only half the items or even only a third of the items on a subtest can be administered to get an estimate of the persons' performance on each subtest and in this way estimate their overall IQ. Both methods have been used on the WAIS and WAIS-R, although the reduction of the subtests is favoured. Both should now be validated and considered for use with the WATS-III in South Africa. Wechsler tests and their constituent subtests have been found to be differentially effected by race, education, language and socio-economic status (Kaufman, McLean & Reynolds, 1988; Nell 1999). These differences have also been found to impact on the short forms which are suggested, as certain subtests are considered to be more biased towards particular groups than others. Vocabulary and Block Design in particular bias testees who are not as westernised or acculturated towards a largely American and European culture (Kaufman, McLean & Reynolds, 1988). These differences, although often ascribed to race, language or socio-economic status can best be understood more broadly in terms of degree of acculturation (i.e. westernisation) (Shuttleworth-Jordan, 1996) and test-wiseness (Nell, 1999). In South Africa in particular, with its extreme cultural diversity these factors need to be carefully considered when developing short forms. In the present study the development of a short form appropriate to South Africa's diverse cultural circumstances will be approached, through a sample which has been stratified according to gender, first language (English vs. African), quality of schooling received (Private/Model C vs. DET) and level of education achieved (Matric vs. Graduate). Both a subtest reduction method and an item reduction method will be considered to arrive at a short form. The subtest reduction method will be considered further in an attempt to clarify which subtests would be more or less appropriate to include in a short form considering group differences. Finally the thesis will develop suggestions as to which short forms would be best for use in South Africa.
