Exploring the interrelation between OPQ, 15FQ+ and the SDS questionnaire

Abstract

Orientation In this study the interrelationship between specific personality and interests measures were explored to improve understanding of the respective constructs and their interrelations. A literature study and empirical research was conducted to serve the purpose of this study. Research purpose The purpose of this study was to explore the interrelationship between personality and interests using the measures of the OPQ, the 15FQ+, and the SDS. Motivation for study Much research has been done on the importance of the use of personality and interest questionnaires for career guidance and other purposes. However, a correlation between the SDS and OPQ and between the SDS and 15FQ+ has not been researched. As such, this study was intended to provide valuable insight into the interrelation between the personality and interests as measured by the OPQ, the SDS and the 15FQ+, which should enhance the interpretation of the respective constructs. Research Methodology An exploratory research method was used, as it was a systematic investigation of the relationship among two or more variables. A quantitative strategy of inquiry was used for this study. Main findings A canonical correlation analysis showed moderate to strong interrelationship between personality traits and vocational interest. The interrelation of the OPQ, the SDS and the 15FQ+ are significant. The findings indicated how personality and interests differ and converge for enhancing interpretation purposes. Practical/managerial implications Holland’s theory of vocational interests focuses on the application of the SDS for career purposes, as well as for measuring job fit and job satisfaction. A better understanding of the interrelationship between personality and interests help practitioners to optimize the use of the measures within various contexts. Contributions/value additions The study will enable practitioners to more effectively utilize the personality and interest measures, combined or separately, as the interrelationships are now better known and construct validity is enhanced. Conclusion The objective of this research was successfully achieved, as satisfactory evidence was provided to address the overarching research purpose.
