The effects of tenure on police officer personality functioning

The study compared pre-employment and current MMPI/MMPI-2 Basic Scale scores of small- and mid-size city Texas municipal police officers to assess longitudinal personality change. Participants had at least five years continuous, “street level” police experience. Twenty-three veteran police officers from a mid-size city and 19 small-city police officers volunteered to participate. Pre-employment MMPI/MMPI-2 information was obtained from police department records. Current MMPI-2 data was collected in small group or individual administrations. Significant increases in K-corrected T-Scores occurred on Scale F and eight of the Basic Scales; L and K decreased significantly. Mean scores remained within the normal range. Mid-size city officers produced higher K and 5 scores than small-city officers. Authors' Note: We gratefully acknowledge the assistance of Rick Bradstreet, Ph.D., and E. S. Collins, Chief of Police, in the data collection process. The results of this study were presented at the Annual Convention of the American Psychological Society in Denver, Colorado, in June 1999.

This paperaddresses this topic by presenting the results of an extensivesurvey comparison experiment conducted as part of the 2005 BritishElection Study. Analyses show statistically significant, butgenerally small, differences in distributions of key explanatoryvariables in models of turnout and party choice. Estimatingmodel parameters reveals that there are few statistically significantdifferences between coefficients generated using the in-personand Internet data, and the relative explanatory power of rivalmodels is virtually identical for the two types of data. Ingeneral, the in-person and Internet data tell very similar storiesabout what matters for turnout and party preference in Britain.Determining if similar findings obtain in other countries shouldhave high priority on the research agenda for national electionstudies.
