METHODOLOGY IN THE ASSESSMENT OF STRESS AMONG AIR TRAFFIC CONTROL SPECIALISTS (ATCS): NORMATIVE ADULT DATA FOR THE STATE-TRAIT ANXIETY INVENTORY FROM NON-ATCS POPULATIONS

Federal Aviation Administration (FAA) studies of psychological work stress among air traffic control specialists (ATCSs) have typically employed the Spielberger State-Trait Anxiety Inventory (STAI) to assess stress. Interpretation of the findings has been tempered by concern that use of the college student normative data available for this test might underestimate actual ATCS stress levels. Since ATCSs differ from college students in a number of respects, a study was undertaken to obtain baseline STAI data from a sample of adult, non-ATCS FAA personnel. Biographical and STAI data were collected from 1,972 men and women, ranging in age from the twenties into the sixties. Respondents were classified according to age, sex, education, occupational supervisory level, and degrees of present work-shift difficulty. STAI scores were compared according to each method of classification. Significant age differences were found for both State and Trait anxiety scores in comparisons involving the 25-29 and the 60-69 year age groups. However, there were no differences in State or Trait anxiety scores between age groups below 60. Comparisons of the scores of individuals within the 25-59 year age range with college undergraduate data revealed either no differences or significantly higher anxiety scores for the college undergraduate group. No significant differences in State or Trait anxiety scores were found between men and women, between different levels of occupational supervision, or between different educational levels. State anxiety scores were found to differ significantly in relation to work shift difficulty, with shifts rated as "very difficult" having higher state scores than shift ratings of lower difficulty; these changes, however, were not appreciably different from those previously obtained for ATCSs.
