South African personality inventory : the development of an investigation into the psychometric properties of the intellect cluster / A. Labuschagne

Labuschagne, Antoinette January 2010 (has links)
The Employment Equity Act, 55 of 1998, Section 8 (Government Gazette, 1998) provides clear guidelines for psychometric testing in South Africa. Due to the cultural complexity of the South African population, personality tests in particular do not always comply with these specifications. Most personality tests used in South Africa have been developed in and imported from other countries, and are consequently not always appropriate for all cultural groups. Also, the majority of indigenous personality tests were developed and standardised specifically for the white population. Today a major challenge in personality assessment development is to develop and standardise inventories for the 11 official language groups in South Africa. The objectives of this study were to develop valid and reliable items for an Intellect–measuring instrument that will form part of a larger personality inventory, to investigate the factor solution of this Intellect cluster, and to compare the factor solutions of the white and African race groups respectively. An Intellect questionnaire consisting of 202 items was developed based on the qualitative phase of the South African Personality Inventory (SAPI). This research served as a pilot study. The sample consisted of (N=524) students from tertiary institutions in the Gauteng and the North West Provinces of South Africa. A quantitative design with an exploratory approach was used to collect data. Statistical analysis was used to analyse the data. The results indicated that only 18 of the original 202 items proved to be unreliable. Acceptable reliability levels for all facets were found. First–order factor analysis produced two sub–clusters: Aesthetics and Intellect. The Aesthetics sub–cluster consisted of the Artistic, Concrete work and Creative facets, and the Intellect sub–cluster consisted of the Intellect, Knowledgeable, Logical, Self–insight, Articulate, Competent, Enterprising, Perceptive, Social Intellect and Understanding facets. Second–order factor analysis indicated a single–order factor for the Intellect cluster with two second–order factors: Aesthetics and Intellect. Support was found to discard the Musical and Enterprising facets from the Intellect cluster. Similar factor solutions were found for the white and African groups - except for the Musical facet, which loaded on the Aesthetics sub–cluster for the white group and on the Intellect sub–cluster for the African group. Recommendations were made for future research. / Thesis (M.Com. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2011.

Developing and validating a measuring instrument for the Relationship Harmony personality cluster / Oosthuizen, T.H.

Oosthuizen, Talitha Helena January 2011 (has links)
The object of this study was to develop a valid and reliable measuring instrument for the Relationship Harmony personality cluster as part of the overall SAPI project, a project that aims to develop a valid, reliable, fair and unbiased personality measuring instrument that can be used within the South African context. Due to the large item pool (i.e. 400 items) two questionnaire versions were developed, namely RH–1 and RH–2. A pilot study was conducted with both versions on participating students from tertiary institutions within the North West and Gauteng Provinces (RH–1: n = 507; RH–2: N = 475). Items indicating unacceptable kurtosis were excluded from further analyses due to their unsuitability for factor analysis. Principal component analyses indicated that 31 items from RH–1 and 24 items from RH–2 shared less than 5% of their variance with the total score. These items were thus excluded from further analyses. Principal component analyses were also conducted to determine the correlations between the 23 facets and their relating items. This procedure resulted in another 3 items being removed due to loadings < 0.20. First–order unstructured factor analysis techniques (scree plot, eigenvalues and parallel analysis) indicated that three factors should be retained for RH–1 and two factors for RH–2. Oblique rotations produced factor correlation matrices for both sets of data. Maximum likelihood was used to analyse the factor structure of the Relationship Harmony cluster in both data sets. The data sets were then subjected to higher order factor analysis. A hierarchical Schmid–Leiman factor solution produced a three factor solution for RH–1 (Negative Relational Behaviour, Positive Relational Behaviour and Approachability) and a two factor solution for RH–2 (Positive Relational Behaviour and Negative Relational Behaviour). Construct equivalence across the White and African groups was evaluated by comparing the factor pattern matrices. For RH–1, all facets except for Tolerant loaded on the same factors for both race groups. RH–2’s factors were represented by the same facets irrespective of the race groups. Recommendations were made for future research. / Thesis (M.Com. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2012.

Investigation of the optimal response scale for personality measurement : computer–based testing / Elizabeth Maria Classen

Classen, Elizabeth Maria January 2011 (has links)
return and payback period. All these above techniques will be analysed in three different scenarios, namely: 1. Mine X will stay with its current operations without any new projects. 2. The development project will begin immediately. 3. A six–month delay in development of the project. The study found that the net present value was positive, the internal rate of return was more than the discount rate and the payback period was shorter than the project’s life–time regarding to all three above–mentioned scenarios. The highest net present value is calculated in case the project starts immediately. Both the internal rate of return and the payback period indicated that a six month delay in the project is the most viable. After considering all the facts, the study concluded due to the highest net present value the best feasible recommendation would be to start the project immediately. The value of this study is that it is the first study to investigate the relationship between the viability to delay or to start the investment project immediately in the South African mining industry. This study is also unique, since it takes into account how mining industries world–wide can achieve long–term success through development projects without losing key players, due to impulsive short–term downsizing decisions. To be able to use personality tests in the most reliable and valid manner there are many considerations to be taken into account. Variables such as the population used, the culture of the test–takers, the mode of administration, whether pencil–and–paper or computer–based testing procedures, familiarity with computers when using computer–based tests and the response format to be used when administering the personality questionnaire are but some of the considerations. Within South Africa it is that much more important to consider the mode of administration, whether pencil–and–paper tests or computer–based tests, as there are many individual groups who have been historically disadvantaged when it comes to the use of computers as a testing method. It is just as important to consider the response scale to be utilised when administering personality testing as this may influence the results obtained and can influence the reliability and validity of these results. The objective of this study was to determine which response scale, dichotomous or polytomous, was the best to use when conducting computer–based personality testing. The questionnaire that was utilised was the South African Personality Inventory (SAPI) questionnaire; however, only items from the Soft–Heartedness cluster were employed as the objective was not to test the questionnaire but to test the most reliable and valid response scale to be used in conjunction with the questionnaire. A convenience sampling approach was utilised and the questionnaire was administered to students who were available and able to take the test (N = 724). Descriptive statistics, factor analysis and Cronbach Alpha coefficients were used to analyse the data obtained. / Thesis (M.Com.

An exploration of social desirability within the white Afrikaans-speaking group / Tarina Kemp

Kemp, Tarina January 2013 (has links)
South Africa has gone through immense changes in the past two decades. The period around 1994 has been characterised by a comprehensive set of political, social and economic changes, which greatly influenced not only the lives of individuals in this county but also many businesses, organisations and companies. Further to this, South Africa has become increasingly intercultural in orientation as companies persevered in establishing intricate networks with partners in a diverse set of cultures. This has put enormous strain on organisations to remain competitive in the market. It is critical that organisations develop a more resilient workforce with greater psychological capacities to succeed in the on-going war for talent. Attracting and retaining talented employees can give organisations a sustained competitive advantage. In view of the growing intricacies in the business world, ambiguity in markets, and employees’ attitudes, it is crucial that organisations invest in psychological assessments. However, investing in valid and reliable psychological assessments has become more difficult due to vast cultural diversity South Africa comprises off. The general objective of this study was to explore social desirability in the white Afrikaans group. A qualitative design was used and a quota non-probability sampling method was implemented among white Afrikaans-speaking people of South Africa (N=60), who differed from one another with regard to age, gender and socio-economic status. The measuring instrument was a semi-structured interview, which was based on the phenomenological approach. The results of the interviews were transcribed and captured in Excel. Content analysis was used to interpret the responses in socially desirable themes. Independent psychologists and language and cultural experts were employed in order to validate the initial interpretations. The descriptive terms were reduced through the use of cluster analysis. The analysis included the grouping of synonyms and antonyms, together with the use of dictionaries, literature and knowledge about content. In the representation of social desirability and impression management strategies within the white Afrikaner group, six main themes with sixty sub-themes in total were identified. The six themes are facilitating, gender-based, intellect-openness, interpersonal relatedness, intrapersonal relatedness and value-based. Firstly, to facilitate others by giving advice and guidance will be seen as desirable and make a favourable impression. Secondly, to display characteristics that are typically associated with males and females, such as masculinity and femininity, will be seen as desirable and can make a positive impression. Thirdly, having a unique natural ability or skill and being receptive to new and different ideas will be seen as desirable and make a good impression on others. Fourthly, remaining constructive in one’s relationships, and fifthly, remaining constructive in one’s inner thoughts and possessing inner confidence and having respect will make a favourable impression and can be seen as socially desirable. Lastly, exhibiting moral consciousness and being trustworthy, loyal and reliable will make a positive impression and will be perceived as desirable by the white Afrikaner group. Recommendations for future research and for practice were made. / MCom (Industrial Psychology), North-West University, Potchefstroom Campus, 2014
