An investigation of biographical information as a predictor of employment termination among law enforcement officers

Among the most important services that psychology can offer law enforcement is assistance in the selection of future officers. The usual contribution made by police psychologists centers on the elimination of applicatns who are mentally ill. However, due to increased behavior-generated police liability, psychologists must focus on ruling out applicants whose future behavior may result in departmental compromise for any reason. One method for forecasting police officer performance is by examining critical information in biographical data. This paper examined the predictive validity of biographical information for a sample of 2,965 police officer candidates. Results indicated that several biographical variables were significantly correlated with later police officer termination. However, results of regression analyses indicated that biographical variables alone accounted for limited variance in the prediction of police officer termination. These findings suggested that the use of biographical information as a sole determinant of police candidates was not supported and the use of additional sources of data would likely be required for practical forecasting purposes.
