The BOSS, which has been developed and tested on both a sleep clinic and general population sample of drivers, has significantly better positive predictive value for sleep-related traffic accidents than the ESS and SAW for the cohort of patients. This means that a driver is more likely to have an accident when the BOSS is positive compared to a positive ESS or SAW. It also has the best balance between sensitivity and specificity regarding the accident risk in both groups. By including sleep clinic patients and the general population interviewed via internet we were able to demonstrate its validity. Although the BOSS is intended to identify patients at risk in the clinic, the validation on the large internet cohort of the general population is interesting since the situational risk factor SAW is derived from the latter.
