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. / Thesis (M.A.)-University of Natal, Durban, 2000.
