Associations of occupational stress, workplace violence, and organizational support on chronic fatigue syndrome among nurses.

Workplace violence, organizational support, and occupational stress were related to chronic fatigue syndrome, which helped to explain why Chinese nurses suffered higher prevalence of chronic fatigue syndrome. Overcommitment explained chronic fatigue syndrome better than Effort/Reward Ratio, so intrinsic stress played a more critical role than extrinsic stress in chronic fatigue syndrome. Chinese nurses suffered serious sleep disorders and impairment of concentration and memory. These symptoms might also attribute to serious occupational stress, unsafe and unsupportive working environment. Creating a safe and supportive working environment, relieving intrinsic occupational stress should be considered as an institutional strategy to early prevent chronic fatigue syndrome.
