Validation of the revised edition (1995) of the locus of control inventory

Abstract

The principal objective of the study was to determine the cognitive, educational and personality correlates of the revised edition (1995) of the Locus of Control Inventory (LCI). The three-factor-structure of the LCI was confirmed by Schepers (2004a, pp. 36-41). The obtained factors were interpreted as External Control, Internal Control and Autonomy. The resulting scales yielded reliabilities of 0,841, 0,832 and 0,866 respectively. As far as validity is concerned statistically significant relationships were found with the matric mark, and with several measures of the Sixteen Personality Factor Questionnaire, the Personal, Home, Social and Formal Relations Questionnaire, the Survey of Study Habits and Attitudes, and the Learning and Study Strategies Inventory. The implications of the findings are discussed.
