Martinussen et al. (2007) compared “burnout” among a sample of Norwegian police officers to a comparison group of air traffic controllers, journalists, and building constructors. Burnout was measured on three scales: exhaustion, cynicism, and efficacy. The data are summarized in Table 5.24. The authors state,

The overall level of burnout was not high among police compared to other occupational groups sampled from Norway. In fact, police scored significantly lower on exhaustion and cynicism than the comparison group, and the difference between groups was largest for exhaustion.
