简要总结
The purpose of this study is to examine whether repeated exposure to an active shooter or target practice virtual reality (VR) scenario alters physiological and psychological stress responses over time. Specifically, this study will determine whether the pattern and magnitude of stress habituation differ between the two VR conditions.
详细描述
This study examines the effects of repeated virtual reality (VR) exposure on physiological and psychological stress responses by comparing an active shooter scenario with a target practice scenario. Repeated exposure to a stressor may result in changes in physiological and psychological responses over time, a process known as stress habituation. Therefore, the goal of this study is to determine whether repeated exposure to these two VR scenarios results in different patterns of stress habituation. Heart rate, salivary stress biomarkers, and self-reported anxiety will be assessed across repeated VR exposures to evaluate changes in stress responses over time. The findings from this research may provide insight into how stress responses change with repeated exposure to different types of VR scenarios and may inform the development of training approaches for individuals in high-stress occupations.

结局指标
主要结局
State Anxiety Inventory (SAI)
时间窗: Timepoint 1-4 were 20 minutes pre, immediately pre, immediately post, and 15 minutes post
The SAI is a 6 question survey on a 24 point scale, asking the subject to record how they feel. Questions asked were "I am calm," I am tense," "I am worried," "I am relaxed," etc. Subjects were asked to fill this out 4 times throughout the study, alongside HR and saliva samples.
Heart Rate
时间窗: HR was recorded 4 times, before each saliva sample period
Heart rate was recorded immediately prior to each saliva sample using a Polar Verity Sense heart rate wrist/arm strap.
Secretory Immunoglobulin-A
时间窗: Measured using the saliva samples taken at timepoints 1-4 (20 min pre, immediately pre, immediately post, 15 min post)
SIgA is a marker of immune function and salivary SIgA concentrations tend to increase when exposed to stress
Salivary Alpha Amylase
时间窗: Measured using the saliva samples taken at timepoints 1-4 (20 min pre, immediately pre, immediately post, 15 min post)
sAA is an enzyme involved in digestive processes. Amylase concentrations in saliva have been shown to reflect sympathetic stress. Thus, as sympathetic stress increases, salivary amylase concentrations tend to increase.
