Occupational stress often stems from unexpected responsibilities and pressures that do not align with a person's knowledge, skills, or expectations, inhibiting one's ability to cope. Occupational stress can increase when workers do not feel supported by supervisors or colleagues, or feel as if they have little control over work processes. Because stress results from the complex interactions between a large system of interrelated variables, there are several psychological theories and models that address occupational stress.

Epigenetics of anxiety and stress-related disorders triggered PTSD. "Nr3c1" is a gene that encodes a glucocorticoid receptor (GR) and contains many GR response elements. Early life stress increases methylation of the 1 promoter in this gene (or the 1 promoter analog in rodents). Because of its role in stress response and its link to early life stress, this gene has been of particular interest in the context of PTSD and has been studied in PTSD of both combat veterans and civilians. In studies involving combat veterans, those who developed PTSD had lowered methylation of the "Nr3c1" 1 promoter compared to those who did not develop PTSD.
