AN ASSESSMENT OF THE EFFECTIVENESS OF THE MANN ATTITUDE INVENTORY AS A PREDICTOR OF FUTURE DRIVING BEHAVIOR

THE FIRST PURPOSE OF THE STUDY WAS TO DETERMINE WHETHER THE FINDINGS OF KENEL, REGARDING THE RELATIONSHIP BETWEEN OBSERVED RATING AND DRIVING BEHAVIOR, ENDURED OVER AN EXTENDED PERIOD OF TIME. THE SECOND PURPOSE WAS TO DETERMINE IF THE MANN INVENTORY RATING AND DRIVING RECORD CORRELATED SIGNIFICANTLY IN A 26-MONTH AND A 60-MONTH PERIOD OF TIME; AND THE THIRD PURPOSE WAS TO DETERMINE WHICH OF THE TWO RATINGS, TEACHER OBSERED OR MANN INVENTORY, HAD MORE PREDICTIVE VALIDITY. FOUR HUNDRED AND SIXTY-FOUR MALE STUDENTS WHO WERE PART OF KENEL'S STUDY WERE SELECTED FOR THIS STUDY. THE HYPOTHESES WERE TESTED USING A ONE-WAY ANALYSIS OF VARIANCE, AND STATISTICAL ANALYSIS REVEALED: (1) WHEN STUDENTS ARE GROUPED ON THE BASIS OF OBSERVED BEHAVIOR THE GROUPINGS ARE SIGNIFICANT AS THEY RELATE TO VIOLATIONS, SECRETARY OF STATE ACTION, AND COMPREHENSIVE RECORDS. THIS OCCURRED IN BOTH THE ORIGINAL AS WELL AS THE FOLLOW-UP PERIOD. ACCIDENT EXPERIENCE WAS SIGNIFICANT IN THE ORIGINAL PERIOD, BUT NOT IN THE FOLLOW-UP PERIOD. (2) WHEN STUDENTS WERE GROUPED ON THE BASIS OF THE MANN INVENTORY RATINGS, THE GROUPOINGSWERE SIGNIFICANT FOR VIOLATIONS, SECRETARY OF STATE ACTION, AND COMPREHENSIVE RECORDS IN THE ORIGINAL AS WELL AS THE FOLLOW-UP PERIOD. THE GROUPINGS WERE NOT SIGNIFICANT FOR EITHER TIME PERIOD FOR CHARGEABLE OR NON- CHARGEABLE ACCIDENTS. (3) BOTH THE MANN ATTITUDE INVENTORY RATINGS AND THE TEACHER OBSERVED RATINGS FOR VIOLATIONS, SECRETARY OF STATE ACTION, AND COMPREHENSIVE RECORDS WERE SIGNIFICANT AT THE .05 LEVEL OR BOTTER FOR BOTH TIME PERIODS. /AUTHOR/
