| Description |
Intercorrelations between 121 predictors and 29 job related criteria obtained from 114 Salt Lake City policemen were analyzed in order to determine the extent to which the predictors could account for the policemen's job performance. Predictor data consisted of 108 biographical items and 13 scales provided by the MMPI. Partial correlations we re computed for selected predictor-criterion combinations when it became apparent that the length of tine each patrolman had been on the force was highly correlated with most of the remaining criteria. The results of the correlational analysis were : A total of 225 significant correlations were obtained bet-ween the predictors and criterion used in this study. One hundred and sixty-two of these were significant at the . C5 level and 63 were significant at the .01 level. In addition, 33 part i a l correlations were obtained which were significant at at least the. OS level. Approximately 175 significant correlations were expected to OCCU1' by chalice alone for the 3, 509) comparisons made, assuming all comparisons were made between .independent variables. MMPI: Seventeen significant correlations were obtrained between the MMPI scales and the criteria. Sixteen of these we re significant at the .05 level and one was significant at the .01 level. In addition, seven partiaI correlations were obtained which were significant at at least the .05 level. Approximately 19 significant correlations were expected to occur by chance alone for the 377 comparisons made. Biographical data: A total of 208 significant correlations were obtained between the biographical data and the criteria. One hundred and fIfty-one of these were significant at the as level and 57 were significant at the .01 level. In addition 26 significant partial correlations were obtained which were significant at at Least the .05 level. Approximately 157 significant correIations were expected to occur by chance alone for the 3,132 comparisons made. The obtained relationships were briefly discussed in light of their potential value as predictors of police performance. Definitive conclusions regarding the extent to which the predictors used in this study would , if further refined by statistical analyses, predict these criteria were withheld pending the completion of such analyses. |
