Reliability of the 16PF questionnaire for security guard applicants

The Sixteen Personality Factor Questionnaire (16PF) was administered to a group of security guard applicants to determine its retest reliability after a moderate (9-month) interval. All of the Pearson correlations for specific test scales were lower than the reliabilities reported by the test's authors. These data raise questions as to the usefulness of the 16PF for the prediction of security guard behavior.
