On the distinction between physical and psychological stressors

The distinction between physical and psychological stressors is reviewed, including some implications for anxiety research. The relationships among anxiety states, anxiety traits, and type of stressor are complex and can be influenced by such factors as the preciseness by which the stressor is identified, how it is measured, and the coping mechanisms available to deal with the stress. The choice of appropriate state and trait anxiety measures is crucial when assessing the differential impact of physical and psychological stressors.
