The Human Stress Response in a Simulated ED Setting

Description

Aim 1: Determine the feasibility and acceptability of an ED-relevant stressor task as compared to a standard social stressor task. The investigators hypothesize that an ED-relevant stressor task will be feasible, as measured by the ability to recruit/randomize/retain participants, and as acceptable to participants as a standard social stressor task.

Aim 2: Measure the stress response (alpha-amylase, cortisol, vital signs) in participants who undergo an ED-relevant stress task compared to a standard social stress task. The investigators hypothesize that norepinephrine release will be adequately assessed by salivary alpha-amylase and that an ED-relevant stressor task will elicit similar or greater physiological responses as a standard social stress task.

Aim 3: Evaluate the ED-representativeness of an ED-relevant stressor task compared to a standard social stressor task. Although both tasks will be performed in a simulated ED room in the UAMS Simulation Center, the investigators hypothesize that an ED-relevant task will be rated as more representative of an actual ED visit.

Aim 4: Evaluate ethological ratings of non-verbal behavior thought to indicate assertion and ratings of agitation using rating scales commonly employed in the clinical environment for this purpose. Participants undergoing stress sometimes display symptoms of assertion or agitation, but it is unknown when or how often this occurs. The investigators hypothesize that ethological ratings will be correlated with agitation scale scores and physiological changes.
