An Investigation of Biographical Information as a Predictor of Employment Termination among Law Enforcement Officers

An important service that police psychology can offer law enforcement administrators is assistance in the selection of future officers. Police psychologists have traditionally focused on the identification of psychopathology and exclusion of applicants who were found to be mentally ill. The introduction of the Americans with Disabilities Act (1990) has changed what had been considered appropriate exclusion criteria because of the introduction of increased civil rights protections for persons with disabilities. At the same time, increasing civil liability for law enforcement departments in regard to officer misconduct has compelled police psychologist to evaluate potential for future misconduct by non-clinical means. The scientific examination of biographical data may be one method of establishing the relationship between officer candidate variables and future misconduct. This paper examined the predictive validity of biographical information for a sample of 2965 police officer candidates. Results indicated that several biographical variables were significantly correlated with later termination. However, results of regression analyses indicated that biographical variables alone accounted for limited variance in the prediction of police officer termination. The use of biographical information as a sole determinant of police candidate suitability was not supported and the use of additional sources of data would be required for effectual forecasting purposes.
