Psychometric instruments are used internationally in organisations to assist companies when making recruitment or development decisions. But the differences that exist on similar psychometric instruments between international groups of people with similar qualifications necessitate the evaluation of the construct validity of these instruments. The objective of this study was to determine the construct validity of the locus of control inventory developed by Udai Pareek in 1998. The instrument consists of 30 items and it was completed by 155 pre-and postgraduate students at the University of Pretoria. Oblimin rotation was used to assist with the interpretation of the factors. In the pattern and structure matrix the highest loadings were highlighted which meant that these items measured the construct that they were supposed to measure. Items were deleted where there was no clear indication as to what the item was measuring. Item analysis was done on each of the constructs identified to further investigate the appropriateness of each item and even more items were deleted, which also had an impact on the Cronbach’s alpha value. The chi-square as well as other fit indices was used to determine the model fit. Confirmatory factor analysis was conducted to establish how well the model fitted the data. It was clear that the two-factor model fitted the data considerably better than the three-factor model because of a high correlation between two of the factors which indicated that they might be measuring the same construct. The results indicate that the locus of control instrument is not suitable for use in the South African context and should therefore be modified until a satisfactory model fit is found. AFRIKAANS: Psigometrise instrumente word wereldwyd benut om maatsappye te help met werwing en ontwikkelings besluite. Maar die verskille wat ontstaan wanneer internasionale groepe met soortgelyke kwalifikasies teen mekaar opgeweeg word vereis dat die konstruk geldigheid van die instrumente bepaal word. Die doel van die studie was om die konstruk geldigheid van die lokus van kontrole vraelys, wat deur Udai Pareek ontwikkel is, te ondersoek.Die instrument bestaan uit 30 items en dit was voltooi deur 155 voor-en nagraadse studente van die Universiteit van Pretoria. Oblimin rotasie was gebruik om die interpretasie van die faktore te vergemaklik. Die items wat werklik meet wat dit ontwikkel is om te meet is ingekleur sodat dit maklik geidentifiseer kan word.Items is slegs uit die vraelys gehaal waar daar geen duidelike indikasie was wat die item meet nie. Item analise was op elke konstruk toegepas, en die chi-square en ander passings indekse was gebruik om te bepaal hoe die model op die data pas. Dit was duidelik dat die twee-faktor model die data baie beter pas as die voorgestelde drie-faktor model. Volgens die drie faktor model is daar twee van die voorgestelde drie faktore wat moontlik die selfde konstruk kan meet. Die resultate dui aan dat die lokus van kontrole vraelys nie geskik is vir gebruik in Suid–Afrika nie, en sal daarom aangepas moet word totdat „n aanvaarbare model gevind is.
