Psychometric testing is becoming more influential in the recruitment and development of individuals within the corporate environment globally, with over 80% of Fortune 500 companies in the USA and over 75% of the Times Top 100 companies in the UK using psychometric testing, the same trend is emerging in South Africa. The aim of this study was to investigate the possible relationship between an individual’s preferred behavioural approach on various behavioural dimensions and the manner in which they complete a psychometric measure, more specifically, a learning potential measure within the corporate environment, as an individual’s preferred behavioural approach may act as a biasing factor with regard to the result that they obtain. A causal research design was utilised and two psychometric measures used to respectively determine an individual’s preferred behavioural style and learning potential. The sample consisted of 398 economically active adult candidates in either a development or recruitment assessment centre. Both the Personal Profile Analysis (PPA) and Test for Selection and Training (TST) were administered on these 398 individuals. Statistical analysis was carried out on the test results with the use of SPSS and Microsoft Excel. The reliability and validity of the measuring instruments was also ascertained and found acceptable. Descriptive statistics, contingency tables, significant differences, t-test statistics and p-values were used to analyse the data. These statistical methods were used to indicate if a relationship exists. The results indicate that various behavioural dimensions, (Dominance, Influence and Steadiness) amongst individuals within the South African Corporate environment do have an impact on how they complete a learning potential measure, when consideration is given to the speed and accuracy with which they complete such a measure. Recommendations for the organisation and future research were made. / Psychology / M.A. (Research Psychology)

This thesis explores item response theory (IRT) in the Personal Profile Analysis (PPA) from Thomas International. The study contains two parts (Part 1 and Part II) for which two sample groups were collected. For Part I of the research 650 participants were collected via the old form (CPPA25/C7) in the Beijing office of Thomas International in China (male=323, Female=267, missing=60). Part II of the research used the amended form in the same area and collected a sample of 307 (male=185, female=119, missing=3). The study postulates that IRT methods are applicable to forced-choice psychometrics. The results of Part I showed that the current CPPA form functions, to some extent, according to PPA’s original constructs. Part I of the research identified 16 items that need to be amended (called Amend A in this research). The amended form was returned to China for the collection of samples for Part II, and the results are deemed acceptable. The study concludes with a research protocol for PPA-IRT research generated from the current research. The research protocol suggests four levels of analysis for forced choice (FC) psychometrics, namely: 1. Textual analysis, 2. Functional analysis, 3. Dynamic analysis, and 4. Construct analysis. / Psychology / M.A. (Psychology)
