Study On Job Stress And Burnout Of Air Traffic Controller

Objectives To investigate the job stress and burnout status of air traffic controllers(ATCs) and analyze its influencing factors. Assess the relationship between job stress and burnout in air traffic controllers.Methods By cross-sectional studying, 746 air traffic controllers from the North China Air Traffic Management Bureau and the Southwest Air Traffic Management Bureau were enrolled as study participants. Job stress was measured by Job Content Questionnaire(JCQ)and Effort-Reward Imbalance Questionnaire(ERI). Job burnout was measured by Maslach Burnout Inventory-General Survey(MBI-GS). The influencig factors of job stress and burnout, and the relationship between job stress and burnout wre analyzed.Results Of the 658 ATCs, 77.4%(509/658) belonged to Job Demand-Control Model imbalance type of job stress and 34.5%(227/658) belonged ERI type job stress. 128(19.5%)controllers were high requirements/ low independent type of job stress and 211(32.1%)controllers were high effort/ low reward type of job stress, who had high degree of job stress. Of the 658 ATCs, 66.0%(434/658) controllers existed job burnout. Univariate analysis showed that the factors of age, marital status, life events, medical history, sleeping time, personal monthly income, workplace, length of service, position, workplace, views on regular training, emergency affair or unsafe events, shift work and weekly working time had various degrees of influence on the different factor scores of JCQ and ERI(P<0.05).Age, marital status, medical history, sleeping time, personal monthly income, length of service, positon, workplace, shift work, views on regular training, emergency affair or unsafe events and weekly working time had various degrees of influence on the different factor scores of MBI-GS(P < 0.05). Multiple logistic regression analysis showed that the job stress level of JDC imbalance type of ATCs with the older or considering regular training had more disadvantage than advantages were higher(P < 0.05). The ATCs who slept shorter, worked at north China area, had higher professional title, was tower post and approach ATCs, considered regular training had more disadvantage than advantages showed higher job stress level of ERI type(P<0.05). The ATCs who had medical history,slept shorter, handled the emergency, worked exceed 40 h of weekly working time, worked at tower post, considered regular training had more disadvantage than advantages and worked day and night shift had higher job burnout level(P < 0.05). Multiple logistic regression analysis showed that the scores of job burnout dimensions in the ATCs with higher job stress level of ERI type were higher than those with lower degree of job stress(P < 0.05). There were correlations between variables of JCQ, ERI and MBI-GS. Ordinal logistic regression analysis showed that the ATCs with high effort/ high reward and high effort/ low reward type of job stress had higher urnout(P< 0.05). The ATCs with higher overcommitted had stronger burnout(P<0.05). The ATCs with higher job stress level of ERI type had stronger burnout(P<0.05).Conclusions 1 ATCs have higher job stress level and burnout level. 2 Older, North China, higher position, tower and approach and more harm of view on regular training are the risk factors of job stress. Medical history, tower position, more harm of view on regular training, emergency affair, week working hours>40h, and shift work are the risk factors of burnout. The longer sleeping time is the protective factors for job stress and burnout of ATCs. 3 There is positively correlated between job stress and burnout in ATCs. The degree of burnout of ATCs can reflect the job stress level better.
