DRIVER IMPROVEMENT CLINICS OF THE STATE OF NEW JERSEY

THIS STUDY INVESTIGATED THE EFFECTIVENESS OF THE NEW JERSEY DRIVER IMPROVEMENT CLINICS PROGRAM AS A MEANS OF REDUCING ACCIDENTS AND VIOLATIONS. THE STUDY'S IMPACT WAS DRAMATIZED BY THE FINDINGS THAT CONTROLS, WHO MADE UP 37.43 PERCENT OF THE STUDY POPULATION, WERE INVOLVED IN 37.99 PERCENT OF THE PRE-CLINIC ACCIDENTS. IN SOME OF THE ACCIDENT COMPARISONS, EXPERIMENTALS HAD STATISTICALLY SIGNIFICANT LOWER REOFFENSE RATES THAN DID CONTROLS. CONTROLS ACCOUNTED FOR 32.20 PERCENT OF THE PRE-CLINIC VIOLATIONS AND 49.21 PERCENT OF THE POST-CLINIC VIOLATIONS. THUS, ALTHOUGH DATA COLLECTION WAS BIASED AGAINST THE EXPERIMENTALS--FOLLOW-UP RECORDS WERE KEPT FOR A LONGER PERIOD OF TIME THAN WERE THOSE OF THE CONTROLS--THE EXPERIMENTALS WERE SUPERIOR IN POST-COUNTER-MEASURE DRIVING RECORDS. DIFFERENCES IN EXPOSURE FOR EXPERIMENTALS AND CONTROLS WERE COMPENSATED FOR BY THE CONSTRUCTION OF INDICES FOR ACCIDENT AND VIOLATION RATES. THESE INDICES SHOWED THAT EXPERIMENTALS HAD LOWER ACCIDENT AND VIOLATION RATES FOLLOWING THEIR CLINIC EXPERIENCE THAN DID THOSE IN THE CONTROL GROUP OVER A COMPARABLE PERIOD OF TIME. THIS INVESTIGATION VERIFIED THE VALUE OF DRIVER IMPROVEMENT CLINIC PROCESSING AS AN IMPORTANT PROCEDURE FOR ACCIDENT AND VIOLATION REDUCTION. /ARTICLE/
