A review of validation research on structured employment interviews : exploring the threats to validity.
(2000) Garbharran, Ameetha.; Hill, Sonia.
The main purpose of this study was to explore the threats to internal and external validity that international research on structured employment interviews may have been prone to. On the basis of this exploration, suggestions were rendered on how the perceived threats to internal validity could have been managed. In addition, commentary was offered on whether or not the threats to external validity appear to have been actualised in the international studies that were compared. These constituted the secondary aims of the study. In order to accomplish the primary aim of the study a qualitative approach was employed. Using the literature on the threats to internal and external validity as a fundamental point of departure, studies on the two main variants of structured employment interviews (viz. behaviour description interviews and situational interviews) were analysed. This analysis yielded an insight into the potential threats that are likely to have impacted on the validity findings that were obtained in these studies. On the basis of these insights, suggestions, pertaining to how the threats to internal validity could have been managed, were proposed. In addition, a meta-analytic technique, for comparing the findings across multiple studies, was employed to comment on whether or not the threats to external validity appear to have manifested in the studies in question. These combined insights served as the foundation for offering a South African perspective on the threats to internal and external validity, which included recommendations on how they could be effectively managed in validation research in the South African context.
