Chapter 30: The ImPACT Neurocognitive Screening Test

AUTHORS: A. Edwards, V. Whitefield, S. Radloff

ABSTRACT: The recent development of computerized neurocognitive screening programmes has revolutionized medical management in the sports concussion arena where there is a need for mass testing of athletes, and repeat follow up testing of the concussed athlete to monitor recovery and facilitate safe return-to-play decisions.  Automated programmes of this type have the facility for more accurate evaluation on timed tasks than paper-and-pencil testing, are time and cost effective in that group testing can be undertaken, and multiple randomized versions of the tasks reduce the problem of practice effects on repeated test occasions.  In South Africa, the ImPACT test (Immediate Post Concussion Assessment and Cognitive Testing) that was developed within a research context at the University of Pittsburgh Medical Center, has been employed for clinical and research purposes since 2003, and is the only test of its type registered with the Health Professional Council of South Africa (HPCSA) for clinical use in this country.  This chapter reviews research data derived using the ImPACT test in respect of players of contact sport from school through to the professional level that attests to the clinical sensitivity of this test in the identification of subtle neurocognitive deficit in association with participation in the contact sport of rugby.  In addition, available South African normative indications in respect of the test are presented and discussed.  Finally, the potential to use the ImPACT test to facilitate medical management and increase safety within other contexts is discussed, such as screening of aviation personnel (pilots and ground control employees) on a regular basis to identify the onset of intellectual dysfunction that might have sinister consequences.

Chapter 29: Using computerised and Internet-based testing in South Africa

AUTHOR: N. Tredoux

ABSTRACT: South Africa was an early adopter of computerised tests, with the earliest testing systems being developed in the late 1970’s. Initially computerised testing systems were developed by state-funded organisations, with some funding from the private sector. As a result of political changes in South Africa, financial support for research and development in Psychometrics in statutory organisations decreased. Psychometrics, and specifically computerised testing, was then advanced by various private commercial interests, with increasing involvement from foreign test publishers. With the development of the World Wide Web and the availability of broadband connectivity, delivery of tests and reports across the Internet became a reality.  Publishers were concerned about piracy of content and cheating by respondents who were doing the tests unsupervised.  The International Test Commission drew up guidelines for computer-based and internet-delivered testing, and these were adapted to the existing South African legislative framework and ethical guidelines for psychologist. A legal battle ensued, resulting in the repeated withdrawal and re-adopting of the South African guidelines. The main point of contention was whether or not unsupervised Internet-based testing should be allowed.  This legal battle eventually led to changes in legislation.  This chapter will discuss the regulatory framework as it currently stands.  The risks attached to different types of computerised implentations of tests will be considered, taking into account the rights of the respondent, the psychometric impact of computerisation, and the exposure for the practitioner to charges of possible misconduct. A proposal for best practice in South Africa will be formulated.

Chapter 17: The MBTI in South africa

AUTHORS: K. Knott, N. Taylor, Y. Niewoudt

ABSTRACT: This chapter provides an introduction to the Myers-Briggs Type Indicator® (MBTI®), a well known and popular measure of personality type.  The basic theory and development of the indicator are covered, followed by a summary of South African research and psychometric properties of this well loved instrument.  In particular, the issues of reliability and validity are addressed, and an analysis of the two current forms, namely Form M and Form Q, is presented.  As the instrument is so widely used, some information on the misuse of type is included and there is a focus on the ethical use in South Africa. A substantial portion of the chapter will be spent on the application of type, and how it can be used to improve self understanding, communication, team work, managing change and conflict, among others.  Lastly, we look at the future of the MBTI and new and exciting ways to bring type to life in different contexts.

Chapter 15: The 15FQ+ in South Africa

AUTHOR: N. Tredoux

ABSTRACT: This chapter will discuss the development of the 15FQ+ and how it differs from the 16PF, which measures the same model of personality. An overview of the questionnaire’s reliability and validity will be done, comparing early studies with newer results.  The effect of language proficiency, reasoning ability and education on the reliability of the questionnaire will be discussed.  Differences between race and language groups of the various scales will be considered, with a discussion of the importance of these differences for the fair use of the questionnaire in South Africa. An overview of South African norms will be presented. Guidelines for the choice of norm groups will be discussed, with particular emphasis on the decision whether to use a general population norm or a smaller norm which would be specific to a given language or race group.  For some assessment situations, the best choice may be to use a simpler questionnaire, or not to assess personality using a questionnaire at all.  Attention will also be given to differences between age groups on the personality dimensions measures by the 15FQ+. The various computer-generated reports available for the 15FQ+ will be considered, to facilitate their appropriate use.  Attention will be given to the practice of matching personality dimensions to competencies, the obtaining of matched scores, and the implications for fair use of the questionnaire. The importance of doing an integrated assessment will be emphasised, and some consideration will be given to additional sources of information that can be used to arrive at a fair and accurate assessment.

Chapter 13: Neuropsychological assessment in SA

AUTHOR: M. Lucas

ABSTRACT: Neuropsychology is frequently defined as the relationship between brain functioning and behavior but with the collapse of Cartesian dualism, this focus has been expanded.  With the mind today seen as the output of the brain it is therefore available to objective consideration as well.  Modern Neuropsychology thus encompasses not only the understanding and interpretation of structural/functional brain systems but includes broader understandings such as the subjective experience of self (Solms, 2006). There have been two traditions in Neuropsychology: A syndrome based approach, dependent upon a clinic-anatomical analysis, which we will refer to as the clinical approach; and a cognitive neuroscientific approach, with close links to information processing and artificial intelligence.  The former approach has its origins in the times of cortical localization beginning with Broca, Wernicke and Charcot, but more recently is based upon integrated theories of brain function; while the latter approach is based on principles of cognitive psychology and assumes that mental activities operate in terms of specialized sub-systems or modules.  It has primarily researched cognitive systems that can be separated out (dissociated) from each other.  Both approaches are complementary, use case studies, experimental designs and quantitative analysis.  Each adds valuable information to the study of the brain and mind and currently they are moving towards a more unified model.

Clinical neuropsychology is primarily concerned with anatomical brain variants and pathology and uses the syndrome-based medical model as its theoretical basis.  Typically this discipline is concerned with assessment, diagnosis, management and rehabilitation of people who have neurocognitive impairment.  Deficits are usually acquired as a result of illness and injury to the nervous system; may be temporary or permanent but measurable by subjective complaints (e.g. I am forgetful) and objective measures (e.g. psychometric tests, neuro-imaging studies). Further, clinical neuropsychology is concerned not only with the cognitive impairments but the emotional and behavioural consequences of such illness and injury.  Most importantly, these areas are assessed within the framework of person’s social and cultural background. Thus, neuropsychological assessment must take place through use of triangulation using firstly, personal narratives, collateral information, medical records and investigations such as neuro-imaging and secondly, extensive knowledge on the part of the psychologist of mind/brain issues, neuroanatomy, pathology and physiology, and thirdly, careful administration, scoring and interpretation of appropriate measures of cognitive, emotional and behavioural functioning.  Test measures may be in the form of appropriate standardised or individualised batteries. In South Africa, Neuropsychologists have typically used the standardized norms supplied by test manufacturers for their middle-class, usually white, clients and made judgements on levels of function using standardized scores and statistical analyses (e.g. standard deviations, z scores, t scores, percentile ranks etc.).  However, this group forms a small part of the South African population, making this approach an invalid one for most South Africans.  There have been attempts to standardize various tests for the local population but this has met with only limited success (e.g. Nell, 1999).  The general failure to produce working norms has been for several reasons: i) population heterogeneity in terms of language, education, socio-economic status and cultural stance ii) a dynamic and emerging population, thus tests standardized for a group have limited life as members become better educated iii) changes in level of test sophistication as communities move from pre-modern (rural) to modern (urban) lifestyles. In the face of these challenges, it has been recommended that neuropsychologists use a more hypothesis driven approach first promulgated by Luria (Solms, 2008) as a basis.  Test scores can be then interpreted from a differential score or pattern analytical approach (Zilmer, Spiers & Culbertson, 2008).

Chapter 12: The Griffiths Scales in South Africa

AUTHOR/S: L. Jacklin, K. Cockcroft

ABSTRACT: The Griffiths scales were developed by Ruth Griffiths O. B. E. The Abilities of Babies was published in 1954 followed by The Abilities of Young Children in 1970.  These scales were used extensively in the United Kingdom and a variety of other countries. Eventually, it became clear that with greater exposure of children to electronic media and early childhood education that there had been acceleration in the development of children. The Griffiths scales had to be updated to keep pace with the changes. This resulted in the publication of the revision of the Birth to 2 years in 1996 and the   Extended Revised Scales for children of between 2 years and eight years in 2006 .This text will describe the history and development of the scales. The Griffiths scales are one of a variety of tests available for assessing the development of young children. What makes them unique is that they can be used to test children from birth up to the developmental age of eight years across all areas of development. They therefore give a complete profile of the development of the child. The strengths and weaknesses of the use of the Griffiths scales as a test and as a research tool in the South African context will be described. The use of the Griffiths scales is controlled by the Association for Research in Infant and Child Development (ARICD) to ensure that the test is administered by suitably trained testers. The training process is described. Assessment and the development of tools is a dynamic process. The future development of the scales is discussed.

Chapter 11: The APIL and TRAM learning potential instruments in South Africa

AUTHOR/S: T. Taylor

ABSTRACT: This chapter covers three main topics involving the APIL and TRAM learning potential instruments developed by Aprolab, namely, the underlying theory, the nature and contents of the instruments and technical information. Early theory by Vogotsky, Feuerstein and others suggested that learning potential is solely reflected in the zone of proximal development, the degree to which an individual’s performance improves with intervention.  APIL and TRAM instruments are based on a broader theory drawn from cognitive psychology, information processing theory and learning theory. This theory incorporates four main elements – fluid intelligence, information processing efficiency, transfer and learning rate. The first two constructs are static (not direct measures of learning potential, but nevertheless critical to learning). The last two dimensions are dynamic (direct measures of learning). Only learning rate is related to the zone of proximal development concept from which the learning potential construct originally arose. There are actually three Aprolab learning potential instruments: APIL, TRAM-2 and TRAM-1. They cover the educational spectrum from no education to tertiary education. All of them are based on the theory mentioned above and incorporate separate measures of the four constructs listed above. In some cases the constructs are broken down into sub-dimensions. APIL has eight scores, TRAM-2 six and TRAM-1 five. The sub-dimensions are described, the techniques whereby the raw-scores are converted into normed scores on these sub-dimensions explained, and examples of stimulus material provided. The APIL and TRAM instruments have been used since the mid-90’s. Technical information is given on scale inter-correlations, reliabilities, predictive and concurrent validity, and culture-fairness/lack of bias.

Chapter 14: The 16PF in South Africa

AUTHORS: N. Taylor, C. Prinsloo, R. van Eeden

ABSTRACT: Personality assessment and the general history of the development of the 16PF are briefly discussed. An overview of the history of the 16PF in South Africa is subsequently given including the development and psychometric properties of older versions of the questionnaire and of related questionnaires. This is followed by a detailed discussion of two versions of the questionnaire, namely the SA92 version and the SA fifth edition. Both versions are locally used and supported by test publishers (although the form SA92 is being phased out in favour of the SA fifth edition). The latter represents current local and international developments and the former is important in terms of the associated research results both from a practical and a methodological point of view. The versions are described in terms of their development and the subsequent research conducted in South Africa. The emphasis is on critical discussion/examination of the instruments in the local context, focusing on cross-cultural research. In addition to comparisons across groups, issues such as the understanding of items, the role of language proficiency and translation difficulties are discussed. Issues related to the 16PF in practice are discussed and the chapter concludes with ideas on the future of the questionnaire in South Africa. Reliability, validity and bias issues are highlighted as far as possible.
