An extension of the use of biodata for managerial selection
The aim of the research was to investigate whether a construct-oriented approach to biodata modelling provides incremental validity over and above other instruments currently employed in the selection of managers. This aim was explored through the development of construct oriented biodata analogues of the constructs of critical thinking ability, extroversion and neuroticism. These models were developed on a pilot sample of 'potential managerial candidates'. The pilot analogue models demonstrated impressive levels of construct validity and the biodata instrument was then validated in a concurrent study based upon managerial job incumbents. Supervisor ratings of performance and a career progress variable provided subjective and objective indicators of managerial performance. Although the psychological constructs of critical thinking ability, extroversion, and neuroticism did not significantly predict either outcome, further analysis of supervisor ratings revealed that perceived conscientiousness and energy contribute much of the variance associated with overall performance ratings, suggesting the likelihood of halo error in the ratings and offering grounds for a social psychological explanation of the results relating to this criterion. Regression analyses revealed that biodata analogue models of critical thinking ability, extroversion and neuroticism demonstrate incremental validity of construct-oriented biodata analogue models over traditional psychometric measures of these constructs. Construct- oriented biographical life history analogues may add considerable utility when used in the pre-selection stage of managerial recruitment and selection.
