The construct equivalence and item bias of the PIB/SpEEx conceptualisation-ability test for members of five language groups in South Africa



Pieter Schaap; Theresa Vermeulen

Department of Human Resource Management, University of Pretoria, South Africa





This study's objective was to determine whether the Potential Index Batteries/Situation Specific Evaluation Expert (PIB/SpEEx) conceptualisation (100) ability test displays construct equivalence and item bias for members of five selected language groups in South Africa. The sample consisted of a non-probability convenience sample (N = 6 261) of members of five language groups (speakers of Afrikaans, English, North Sotho, Setswana and isiZulu) working in the medical and beverage industries or studying at higher-educational institutions. Exploratory factor analysis with target rotations confirmed the PIB/SpEEx 100's construct equivalence for the respondents from these five language groups. No evidence of either uniform or non-uniform item bias of practical significance was found for the sample.

Keywords: Abstract reasoning, psychological instruments, cross-cultural fairness, item bias, test bias
