DROWSINESS AND DRIVING IN A MIDDLE AGED POPULATION

QUESTIONNAIRE RESULTS INDICATED THAT THE INCIDENCE OF DRIVERS AGED 45-70 ADMITTING DROWSINESS WHILE DRIVING IS HIGH. THIS APPEARS RELATED TO MALENESS, YEARLY MILEAGE LOGGED, AND LONG TRIP DRIVING. CATTELL PERSONALITY TESTING REVEALED NO CONSISTENT GROUP OF PERSONALITY TRAITS WHICH CORRELATES WITH GETTING DROWSY. SUBJECTS WHO HANDLED DROWSINESS ESPECIALLY POORLY (THAT IS, FALLING ASLEEP) WERE CHARACTERIZED BY EMOTIONALITY, A TENDENCY TO WORRY, GIVE UP, AND EVADE RESPONSIBILITIES. MANY PHYSICAL FACTORS WERE EXAMINED, BUT ALL FAILED TO REVEAL A CONSISTENT PATTERN OF PHYSICAL DEFECT IN THE DROWSINESS GROUP. /NHTSA/
