CONCEPTS AND PRINCIPLES OF MEASUREMENT WITH APPLICATIONS TO THE EVALUATION OF SAFETY PERFORMANCE

SAFETY PERFORMANCE EVALUATION ATTEMPTS TO USE THE SCIENTIFIC METHOD TO DETERMINE WHETHER A PROGRAM IS ACHIEVING DESIRED RESULTS BUT THE SUCCESS OF SUCH EVALUATIONS DEPENDS MORE UPON ITS ADMINISTRATIVE USEFULNESS THAN SCIENTIFIC CRITERIA OF ACCURACY. ESSENTIAL STEPS IN THE EVALUATION ARE: PROGRAM FORMULATION; ANALYSIS OF THE GOALS, SUBGOALS, AND EXPECTED PROBLEMS; DESCRIPTION AND STANDARDIZATION OF PROGRAM CONTENT; PROGRAM APPLICATION WITHIN A SPECIFIC PROBLEM AREA; MEASUREMENT OF CHANGE AND DETERMINATION OF WHETHER THIS IS DUE TO THE PROGRAM OR OTHER CAUSES; AND DETERMINATION OF THE DURABILITY OF EFFECTS. INSTRUMENTS SUCH AS CRITICAL INCIDENT TECHNIQUES, BEHAVIOR SAMPLING, AND SYSTEM SAFETY ANALYSIS HOLD PROMISE AS IMPROVED MEASURES OF EFFECTIVENESS OF PROGRAMS DESIGNED TO PREVENT ACCIDENTS. /HSL/
