This chapter presents a fresh look at burnout, based a reconceptualization as a work-related syndrome that consists of (1) exhaustion (i.e., a severe loss of energy that results in feelings of both physical and mental exhaustion); (2) mental distance (i.e., a strong reluctance or aversion to work, indifference, and cynicism); (3) cognitive impairment (i.e., memory problems, attention and concentration deficits, and poor cognitive performance); and (4) emotional impairment (i.e., intense emotional reactions such as anger or sadness, and feeling overwhelmed by one’s emotions). This reconceptualization was used to develop a novel questionnaire – the Burnout Assessment Tool (BAT). This chapter reviews recent research with the BAT specifically focusing on its reliability and validity, nomological network, prevalence of burnout, and longitudinal and intervention research. Also, its practical use is discussed. It is concluded that the BAT can be used as a viable, alternative measure that gauges the burnout syndrome (total score), as well as its four constituting components. (download full chapter).
