    Adapting the NEO-PI-3 for a South African context : a pilot study using a South African student population.
    (2011-05-13) Quy, G. S.
    The trait approach to personality is one of the most influential epistemological frameworks in personality psychology and underlies the development of most objective personality inventories. The Revised NEO Personality Inventory (NEO-PI-R) is amongst the most widely used operationalisations of the FFM within personality assessment (Costa and McCrae, 1992). However, recent research (Franklin, 2009; Laher, 2010) suggests that the NEO-PI-R is not wholly applicable within the South African context; as there may be inappropriate items contained within the inventory, both linguistically and culturally. Within the United States, McCrae, Costa and Martin (2004) identified the NEO-PI-R as having specific problematic items, and developed the NEO-PI-3 as a revised “more readable” version of the NEO-PI-R. Thirty-seven items were changed from the original 240 items in the NEO-PI-R to create the NEO-PI-3. However, the modifications made to the NEO-PI-3 did not address all the issues pertinent within the NEO-PI-R from a South African perspective as evidenced in Laher’s (2010) and Franklin’s (2009) studies. This study adapted the NEO-PI-3 by changing specific items informed through Franklin (2009) and Laher’s (2010) research, as well as research conducted within this study on two samples of university lectures at the University of the Witwatersrand. Forty-nine items were changed from the original 240 NEO-PI-R items, retaining 30 items changed from the NEO-PI-3, and preferring 3 of the original NEO-PI-R items to the NEO-PI-3 items. These changes were aimed at making the NEO-PI-3 a more appropriate and applicable instrument both culturally and linguistically within the South African context. This modified inventory was then administered to 175 students at the University of the Witwatersrand to test the inventory’s validity and reliability. The reliability of this modified inventory was assessed through conducting an internal consistency analysis generating alpha coefficients indicating that the inventory was indeed reliable. The construct validity of this modified inventory was assessed through an exploratory factor analysis where five factors did emerge from the analysis; concomitant with the theoretical basis of the FFM. Based on feedback from the participants, both quantitatively and qualitatively, recommendations for future research and further problematic items are identified and discussed. In terms of the reliability of the modified version of the NEO-PI-3, internal consistency coefficients produced within the study suggested that the instrument is reliable, producing moderate to good alpha values, as well as producing evidence of good construct validity. Only 17 items emerged as still being potentially problematic within the modified version of the NEO-PI-3.

    Exploring language bias in the NEO-PI-R
    (2010-03-08T06:49:14Z) Franklin, Dee Ross
    The study explores language bias in the NEO-PI-R both quantitatively and qualitatively. A sample of 28 postgraduate psychology student volunteers completed a questionnaire containing the NEO-PI-R and two open-ended questions about the instrument. These responses were then analysed across English first language and second language speakers to explore issues of bias. Reliability of the NEO-PI-R appeared to be robust at a domain level. The reliability of the facets, while appropriate for the most part, still yielded low alpha coefficients for the Excitement-seeking, Actions, Values and Straightforwardness facets. ANOVA’s at the domain and facet scale levels indicated no significant differences across home language. However ANOVA’s at the item level yielded 33 in total that were problematic, comprising of 12 items that were significant at the 5% level of significance and 21 items at the 10% level of significance. These items were primarily from the N and E domains. Thematic analysis of the open-ended questions of the questionnaire indicated 26 items were difficult to understand and/or inappropriate for the South African context. These items were primarily from the E and A domains. From the original sample of 28 volunteers, two focus groups were formed, comprising of volunteers from the initial sample. The focus groups explored several qualitative issues, including concepts of personality, language and culture and the applicability of the NEO-PI-R for South African user groups. It was perceived that there is a presence of American socio-cultural references within the use of language, grammar and socio-cultural context in the instrument. Thus the results show evidence of language bias in the NEO-PI-R, and subsequently identify particular aspects and items of the instrument that are especially problematic for a South African user group. The present study suggests that the NEO-PI-R would need to be revised to suit the South African context by changing the problematic items.
